The evaluation of garlic accessions is important in the search for superior, adapted and flowering cultivars for botanical seed production. The objective of this work was to assess the agronomic performance, flowering capacity and genetic divergence of 13 experimental garlic accessions bred in Brazil. The experiment was laid out as a completely randomized block design with four replications at Lavras, Minas Gerais, Brazil from May to October 2018. A total of 11 accessions were experimental and two were control varieties, Quitéria and Caçador. The control varieties are commercially produced in Brazil and the 11 experimental accessions are elite. The emergence, emergence speed index, plant height, percentage of overcrowding, average weight of commercial bulb, number of bulbs per bulb, total yield, commercial yield, flowering percentage, length and diameter, soluble solids, titratable acidity, pH and ratio soluble solids and titratable acidity of the exhaust floral were measured. The data obtained were submitted to analysis of variance (p≤0.05), and when significant the effects of genotypes, their means grouped by the Scott-Knott test. We also proceeded to study genetic divergence through multivariate analysis, adopting the canonical variables technique. Variance analysis indicated significant differences between genotypes for emergence speed index, flowering percentage, floral scape diameter, floral scape length and commercial yield. The highest commercial yield and flowering percentage were observed in RAL (8.82 t ha-1) and DDR 6024 (80.92%) access, respectively, which differed only from commercial cultivars (Quitéria and Caçador). The greatest genetic divergence was verified between experimental accessions and commercial cultivars. The experimental accessions presented flowering potential and botanical seed production in the studied region

It is necessary to use virus-free garlic seeds to reach high bulb yields; however, information is needed on the number of generations that these seeds can be grown in field conditions without decreasing bulb yield and quality due to degeneration. Degeneration is dependent on the production season and locality; thus, the objective of this work was to evaluate the degeneration of virus-free garlic cultivars grown in the Semiarid region of the Northeast of Brazil, through three experiments conducted in Portalegre, state of Rio Grande do Norte. Virus-free garlic cultivars were used in the first generation (G1) and second-generation (G2) and cultivars without clonal cleaning (infected) in the third experiment. The experiments were conducted in randomized blocks experimental design, with four replications. The treatments consisted of five cultivars: Amarante, Branco Mossoró, Cateto Roxo, Gravatá, and Hozan. The use of G2 garlic seeds in field conditions is viable, mainly for the cultivars Branco Mossoró and Hozan, which showed lower production losses. However, further evaluations, considering at least four generations, are necessary for these cultivars, since the degeneration level depends on the crop environment.

Studies on the interaction between garlic plant density and virus-free seed size are scarce in Brazil. Thus, this study was installed to evaluate the effect of plant spacing and seed size on garlic traits and yield for infected and virus-free bulbs. Treatments were arranged in a randomized block design and 2x5x3 factorial combination [infected and virus-free bulbs, five plant spacings (210, 260, 300, 360, and 390 cm2 per plant), and three bulbous seed sizes (sieve one, two, and three)]. The highest bulb yield was observed for virus-free seeds at a plant spacing of 390 cm2 plant-1, while the highest commercial yield was verified for 210 cm2 plant-1 spacing. The combination of virus-free seeds, larger bulbs, and 332 cm2 plant-1 spacing promoted the highest leaf area index. For virus-free garlic, lower plant densities resulted in higher yields and garlic bulb quality. The best option for higher yields and improved commercial quality bulbs was the use of medium-sized virus-free bulbils at a plant density of about 300 thousand plants ha-1.

BRS Paranoá? was obtained by the carrot breeding program of Embrapa Hortaliças, aiming to obtain a cultivar adapted to most carrot-producing regions in an organic system. It was developed through selection of half-sib progenies and validated in Brazil. ?BRS Paranoá? is indicated for sowing in the spring/summer seasons especially because it displays high resistance to leaf blight caused by the fungal and bacterial association (Alternaria dauci, Cercospora carotae, and Xanthomonas hortorum pv. carotae) with defoliation between 20 to 25% at 100 days after planting (DAP), eliminating the need to control this disease with chemical pesticides. In addition, it shows high production stability and an outstanding production exceeding 32 t ha-1. ?BRS Paranoá? is an early maturity cultivar, and the harvest can be carried out from 85 DAP when the commercial roots range from 16 to 22 cm, 3 cm diameter, intense orange color, cylindrical shape, and no external or internal physiological defects. The postharvest quality was evaluated and the titratable acidity found was 0.20%, 6.9oBrix soluble solids, 78.40 μg g-1 total carotenoids, and 22.69 μg g-1 ß-carotene (provitamin A). ?BRS Paranoá? was registered and protected by the Ministry of Agriculture, Livestock and Food Supply and its seeds have been marketed by the main vegetable seeds companies in Brazil.

The objective of this work was to evaluate the phenotypic correlations between agronomic characters of garlic (Allium sativum) and to carry out the path analysis, using commercial bulb yield as the main character. The experiment was conducted under field conditions in two harvests (2018 and 2019) in the municipality of Diamantina, in the state of Minas Gerais, Brazil. A total of 13 garlic genotypes were evaluated, of which 11 were experimental and 2 were commercial cultivars. The experimental design used was randomized complete blocks with four replicates. Characters related to plant biometry and bulb yield were evaluated. The phenotypic correlations and the path analysis of the studied characters were carried out. The Phenotypic correlations that showed significant positive effects occurred between commercial bulb yield and plant height, bulb diameter, number of commercial bulbs, mean total bulb mass, mean commercial bulb mass, total bulb yield, and number of bulbils per bulb. However, only number of commercial bulbs and bulb diameter had significant effects (direct and indirect) on commercial bulb yield. Therefore, in genotype genetic breeding programs in the studied region, selection should seek a larger diameter of bulbs and a higher number of commercial bulbs to increase commercial yield. RESUMO - O objetivo deste trabalho foi avaliar as correlações fenotípicas entre características agronômicas de alho (Allium sativum) e realizar análise de trilha, tendo-se utilizado a produtividade comercial de bulbos como característica principal. O experimento foi conduzido sob condições de campo em duas safras (2018 e 2019), no município de Diamantina, no estado de Minas Gerais, Brasil. Um total de 13 genótipos de alho foram avaliados, sendo 11 experimentais e 2 cultivares comerciais. Utilizou-se o delineamento experimental de blocos ao acaso, com quatro repetições. Foram avaliadas características relacionadas à biometria da planta e à produção de bulbos. Foram realizadas as correlações fenotípicas e a análise de trilha das características estudadas. As correlações fenotípicas que apresentaram efeito positivo significativo ocorreram entre produção comercial de bulbos e altura de planta, diâmetro do bulbo, número de bulbos comerciais, massa média de bulbo total, massa média de bulbo comercial, produtividade total de bulbos e número de bulbilhos por bulbo. No entanto, apenas o número de bulbos comerciais e o diâmetro do bulbo tiveram efeitos significativos (direto e indireto) sobre a produtividade comercial de bulbos. Portanto, em programas de melhoramento de genótipos na região estudada, a seleção deve buscar maior diâmetro de bulbos e maior número de bulbos comerciais para incrementar a produtividade comercial.

Garlic is a vegetable that has a high economic importance for Brazil. However, despite increases in garlic bulb production in the last years, Brazil is still dependent on imported garlic to meet the national demand. Thus, proper management practices and the use of virus-free clove-seeds are promising alternatives to ensure a high productivity and profitability. Thus, the objective of this work was to evaluate production characteristics and profitability of conventional and virus-free garlic crops as a function of different clove-seed sizes and plant spacings. Two experiments were conducted simultaneously, using virus-free and conventional garlic plants in Portalegre, state of Rio Grande do Norte, Brazil, in a randomized block experimental design, with four replications. The treatments were arranged in split-plot, with the clove-seed size (large and small) in the plots, and the spacing between plants (7.5, 10.0, 12.5, and 15.0 cm) in the subplots. The combination between the use of virus-free clove-seeds, large clove-seed size, and spacing of 12.5 cm between plants resulted in the highest commercial bulb yield and net income, R$ (BRL) 85,151.00 ha-1. The use of large clove-seeds and spacing of 7.5 cm between plants are recommended for conventional garlic crops. RESUMO O alho é uma hortaliça de grande importância econômica para o Brasil. No entanto, apesar da produtividade do alho brasileiro ter aumentado nos últimos anos, ainda há uma dependência do alho importado para atender a demanda interna. Dessa forma, práticas de manejo e o uso de alho-semente livre de vírus, tornam -se uma alternativa promissora para garantir maiores produtividades e rentabilidade. Assim, o objetivo deste trabalho foi avaliar características de produção e rentabilidade do cultivo de alho convencional e livre de vírus em função do tamanho de bulbilho-semente e espaçamento entre plantas. Dois experimentos foram conduzidos simultaneamente, utilizando alho livre de vírus e convencional, em Portalegre-RN. O delineamento experimental foi o de blocos casualizados, com quatro repetições. Os tratamentos foram dispostos em parcelas subdivididas, sendo as parcelas representadas pelo tamanho dos bulbilhos: grande e pequenos. As subparcelas foram compostas por quatro espaçamentos entre plantas: 7,5; 10,0; 12,5 e 15,0 cm. A combinação entre o alhosemente livre de vírus, bulbilho de tamanho grande e espaçamento de 12,5 cm entre plantas resultou em maior produtividade comercial e receita líquida (R$ 85.151,00 ha-1). Para o alho convencional, sugere-se a utilização de bulbilhos grandes com espaçamento de 7,5 cm entre plantas.

– The objective of this work was to carry out the morphological characterization of strawberry fruit of different genotypes, as well as to verify their postharvest conservation. Six commercial cultivars (Albion, Aromas, Dover, Festival, Pircinque, and San Andreas) and nine experimental clones (MDA01, MDA19, MDA22, MDA23, MCA89, MCA94, MFA443, MOGSC468, and MFA443PR) were evaluated. Fruit were produced on semihydroponic gutters in protected cultivation and classified according to size, shape, color, brightness, achene position, pulp color, ?heart? color, fruit cavity, and sepal position. For the postharvest analysis of fruit, the loss of mass and the appearance of fruit during ten days of storage were determined. The evaluated genotypes show a high similarity to each other regarding morphological characterization. MCA89 and 'Pircinque' are the most divergent genotypes in relation to the others. There is an association between the characteristics large cavity, reniform shape, and medium cavity, which contributes to the indirect selection of desirable characters. On the tenth day of storage, the MDA01, MDA19, MCA89, MFA443, and 'Dover' genotypes still show acceptable conditions for commercialization. Resumo – O objetivo deste trabalho foi realizar a caracterização morfológica de frutos de morango de diferentes genótipos, assim como verificar sua conservação pós-colheita. Seis cultivares comerciais (Albion, Aromas, Dover, Festival, Pircinque e San Andreas) e nove clones experimentais (MDA01, MDA19, MDA22, MDA23, MCA89, MCA94, MFA443, MOGSC468 e MFA443PR) foram avaliados. Os frutos foram produzidos em bancadas semi-hidropônicas, em cultivo protegido, e classificados quanto a tamanho, formato, coloração, brilho, posição do aquênio, coloração da polpa, coloração do “coração”, cavidade do fruto e posição das sépalas. Para a análise de póscolheita dos frutos, foram determinadas a perda de massa e a aparência dos frutos durante dez dias de armazenamento. Os genótipos avaliados apresentam alta similaridade entre si quanto à caracterização morfológica. MCA89 e 'Pircinque' são os genótipos mais divergentes em relação aos demais. Há uma associação entre as características cavidade grande, formato reniforme e cavidade média, o que contribui para a seleção indireta dos caracteres desejáveis. No décimo dia de armazenamento, os genótipos MDA01, MDA19, MCA89, MFA443 e 'Dover' ainda apresentam condições aceitáveis para comercialização. Made available in DSpace on 2022-01-14T15:00:41Z (GMT).

RESUMO O objetivo foi avaliar a adaptabilidade e estabilidade de genótipos de cenoura pelo método REML/BLUP. Os experimentos foram conduzidos em 20 ambientes nos anos de 2010, 2011, 2012 e 2014 em diferentes regiões produtoras de cenoura do Brasil. O delineamento experimental utilizado foi de blocos ao acaso com três repetições e parcelas de 1 m2. Foram avaliadas quatro populações de cenoura em fase de melhoramento: CNPH-14, CNPH-15, CNPH-16 e CNPH-17, as cultivares de polinização aberta BRS Planalto e Brasília e o hibrido Juliana. Aos 100 dias após a semeadura foi determinado em cada parcela o rendimento de raízes com padrão comercial. Foi utilizada a metodologia REML/BLUP para estimar a adaptabilidade e estabilidade dos genótipos. Pôde-se verificar que as populações com melhor desempenho e adaptabilidade e estabilidade nos ambientes estudados foram BRS Planalto, CNPH-14 e CNPH-17. A cultivar Juliana e a população CNPH-15 apresentaram os piores resultados frente à média dos ambientes, e Juliana apresentou adaptação específica a São Gotardo-MG e Canoinhas-SC. As populações CNPH-14 e CNPH-17 possuem adaptação ampla o que facilita a recomendação como futuras cultivares. ABSTRACT The aim was to evaluate the adaptability and stability of the genotypes by REML/BLUP method. The experiments were carried out in 20 environments in the years 2010, 2011, 2012 and 2014 in different carrot producing regions in Brazil. The experimental design was a randomized block design with three replications and plots of 1 m2. Four carrot populations in breeding phase were evaluated: CNPH-14, CNPH-15, CNPH-16 and CNPH-17, the open-pollinated cvs. BRS Planalto and Brasília and the hybrid Juliana. At 100 days after sowing we determined in each plot the root yield with commercial standard. We used the REML/BLUP methodology to estimate the adaptability and stability of genotypes. We observed that populations with better performance and adaptability and stability in the study sites were the populations CNPH-14 and CNPH-17. The cv. Juliana and the population CNPH-15 showed the worst results compared to the average of the environment, and Juliana had specific adaptation to São Gotardo, Minas Gerais State and Canoinhas, Santa Catarina State, Brazil. The populations CNPH-14 and CNPH-17 have broad adaptation which facilitates the recommendation as future cultivars.

Correlations and path analysis between characteristics can aid the selection of important attributes in breeding programs. Thus, the objective of this work was to perform genotypic, phenotypic correlations and path analysis under commercial yield of garlic bulbs, depending on morphological and agronomic variables. The experiment was carried out in 2017 at the Universidade Federal dos Vales do Jequitinhonha e Mucuri and Universidade Federal de Lavras, using ten garlic genotypes, eight trials and two commercial cultivars, Caçador and Jonas. We evaluated: plant height; number of leaves, total bulb number; total bulb mass, total bulb yield, marketable bulb yield and number of cloves per bulb. The genotypic and phenotypic correlations were positive and significant between marketable yield of bulbs with bulb mass, total yield and number of cloves per bulb, indicating that selection based on these characteristics will help increase the yield of garlic. However, only the number of cloves per bulb had a direct effect and a relevant indirect effect on the marketable yield of garlic. RESUMO Correlações e análise de trilha entre características podem auxiliar na seleção de importantes atributos em programas de melhoramento genético. Assim, o objetivo deste trabalho foi avaliar correlações genotípicas, fenotípicas e realizar análise de trilha sob a produtividade comercial de bulbos de alho em função de variáveis morfológicas e agronômicas. O experimento foi realizado em 2017 na Universidade Federal dos Vales do Jequitinhonha e Mucuri e Universidade Federal de Lavras utilizando dez genótipos de alho, sendo oito experimentais e duas cultivares comerciais, Caçador e Jonas. Foram avaliadas: altura de plantas; número de folhas, número de bulbo total; massa de bulbo total, produtividade total de bulbo, produtividade comercial de bulbo e número de bulbilhos por bulbo total. As correlações genotípicas e fenotípicas foram positivas e significativas entre a produtividade comercial de bulbos com massa de bulbo, produtividade total e número de bulbilhos por bulbo total, indicando que a seleção baseada nessas características ajudará a aumentar o rendimento do alho. Entretanto, apenas o número de bulbilhos por bulbo apresentou efeito direto e efeito indireto relevante sobre a produtividade comercial de alho.

Black garlic is produced from chemical and biochemical reactions when the fresh garlic bulb is submitted to specific temperature and moisture conditions. The aim of this study was to evaluate quality and nutritional changes on bulbs before and after the transformation in black garlic, presenting the new product for the consumer, evaluating the purchase intention. Commercial garlic bulbs cv. Amarante were obtained and transformed in black garlic. The color, proximate composition (moisture, crude lipid, crude protein, crude fiber, ash and nitrogen-free extract), total sugars, total phenolics content and antioxidant activity were evaluated on fresh and black garlic bulbs. The transformation of garlic in black garlic resulted in an increase on crude lipid, crude protein, total sugars, antioxidant activity and total phenolic content. A multivariate analysis was performed and the characteristics of nutritional interest were positively related to the black garlic samples and a completely separation of the products before and after processing can be observed, affirming the physical, chemical, nutritional and sensory attributes difference. Only 20% of the surveyed consumers affirmed that they already knew the product and 55% classified the product after visual evaluation between “liked slightly” and “liked very much”, with 62% of purchase intention by the interviewed consumers.

The quality of San Vito tomatoes grown in organic system of production, with 6, 12, 24 and 40 tonnes per hectare of organic compound, at Embrapa Vegetables were evaluated. After harvest, fruits were transported to the postharvest laboratory and submitted for analysis after 0, 5, 10, 15 and 20 days of storage at room temperature (24°C ± 2oC and 32%±2RH). The characteristics evaluated were weight loss, color, firmness, pH, acidity, total soluble solids, vitamin C, lycopene and β carotene. For all variables, there were statistically significant interaction between dose of compost and storage time. It was observed that the first day of storage, levels of organic fertilization did not produce fruit with different levels of acidity, (a*/b*)² relation, weight loss, β carotene, lycopene, pH and firmness, like in the 20 days for the first four variables cited and soluble solids. Doses of organic compost used in the production of “San Vito” tomatoes not consistently influenced the variables studied.

Com o objetivo de ajustar a densidade de plantio e o tamenho de alho semente para as cultivares livre de vírus foi realizado um trabalho na Embrapa Hortaliaças para avaliar características de produção do alho livre de vírus em relação ao infectado em função da densidade de plantio e tamanho de bulbilhos semente.

RESUMO Com o objetivo de avaliar a produção de alho nobre submetido a períodos de vernalização e épocas de plantio, realizou-se um experimento em Baraúna-RN, de maio a outubro de 2012. Os tratamentos foram dispostos no esquema de parcelas subdivididas, delineamento experimental de blocos casualizados completos, com três repetições. Nas parcelas foram alocadas as épocas de plantio (22 de maio, 5 de junho e 23 de junho), e nas subparcelas os períodos de vernalização pré-plantio do alho-semente (4±1°C durante 50, 55, 60, 65 e 70 dias). Foram avaliados comprimento de plantas, número de folhas, ciclo, estande final, massa média de bulbos, percentagem de plantas com bulbos, produtividade total de bulbos, classificação dos bulbos, número de bulbilhos por bulbo e classificação dos bulbilhos. O plantio em 22 de maio proporcionou maiores comprimento de plantas, número de folhas, estande final e massa média de bulbos; o ciclo decresceu com o tempo de vernalização; houve formação de bulbos com diferenciação de bulbilhos em todos os tratamentos sem, entretanto, haver ocorrência de plantas com superbrotamento; a produtividade total de bulbos aumentou com o tempo de vernalização de até 63 dias nos plantios em 22 de maio e 23 de junho, com médias de 5,20 e 3,85 t/ha; a combinação entre o plantio em 22 de maio e 65 dias de vernalização, foi a que proporcionou maior número de bulbilhos por bulbo e maior percentual de bulbos comerciais, distribuídos nas classes 3, 4 e 5. Esses resultados evidenciam ser possível o cultivo de alho nobre na região de Mossoró-RN utilizando o processo de frigorificação do alho-planta. ABSTRACT In order to evaluate the production of noble garlic under vernalization periods and planting times, an experiment was carried out in Baraúna, Rio Grande do Norte State, Brazil, between May and October 2012. Treatments were arranged in a split-plot in randomized complete block experimental design with three replications. The planting dates (May 22, June 5 and June 23) were allocated in the plots, and the periods of vernalization of the bulblets (4±1°C during 50, 55, 60, 65 and 70 days) in the subplot. Plant length, number of leaves, cycle, final stand, average bulb weight, percentage of plants with bulbs, total yield, classification of bulbs, number of bulblets per bulb and classification of bulblets were evaluated. Planting on May 22 provided higher plant length, number of leaves, final stand and bulbs mean mass; cycle decreased by vernalization time; there was formation of bulbs with bulblets differentiation in all treatments without occurring plant shoot proliferation; total yield of bulbs increased with vernalization time up to 63 days in plantations carried out on May 22 and June 23, with averages of 5.20 and 3.85 t/ha; the combination of planting on May 22 and 65 days of vernalization provided greater number of bulblets per bulb and higher percentage of marketable bulbs, distributed in classes 3, 4 and 5. These results show the possibility of noble garlic production in the Mossoró region, using the refrigeration process for bulblets.

Com o presente estudo, objetivou-se o desenvolvimento e a produção de cultivares de alho semi-noble, submetidas a diferentes períodos de vernalização pré-plantio dos bulbos-sementeem dois municípios da Mesorregião Oeste Potiguar.

RESUMOO objetivo desse trabalho foi verificar o efeito do solo pré-cultivado com plantas aromáticas na germinação e no desenvolvimento inicial de plântulas de alface cv. Simpson. A pesquisa foi realizada na Embrapa Hortaliças, Brasília, em bandejas mantidas em casa de vegetação. O experimento foi conduzido em delineamento experimental inteiramente casualizado, com três repetições e onze tratamentos: solo pré-cultivado com hortelã-comum (Mentha x villosa), hortelã-brava (Mentha arvensis), hortelã-pimenta (Mentha piperita), Mentha spp., capim-citronela (Cymbopogon winterianus), capim-limão (Cymbopogon citratus), manjericão de folha larga (Ocimum basilicum), manjericão de folha roxa (Ocimum gratissimun), tomilho (Thymus vulgaris), sálvia (Salvia officinalis) e solo da mesma área sem cultivo prévio de planta aromática (controle). Aos 30 dias após o semeio, foram avaliadas: índice de velocidade de emergência (IVE), taxa de sobrevivência (TS), número de folhas (NF), comprimento da raiz principal (CRP) e da parte aérea (CPA), massa fresca da raiz (MFR) e da parte aérea (MFPA) e massa seca da raiz (MSR) e da parte aérea (MSPA). Os dados foram submetidos à análise de variância e teste de Tukey a 5% de probabilidade. Houve diferença significativa em relação ao IVE, sendo que o tratamento com C. citratus afetou negativamente a emergência das plântulas. O tratamento com M. arvensis apresentou uma TS de apenas 16% das plantas aos 30 dias após a semeadura. O NF foi menor no tratamento com M. arvensis, diferentemente de todos os demais, exceto S. officinalis. A MRF e MFF foram estimuladas pelo tratamento com T. vulgaris sendo superior a todos os outros tratamentos. Os resultados obtidos permitem concluir que houve efeito negativo de M. arvensis e positivo de T. vulgaris no desenvolvimento inicial de plântulas de alface. ABSTRACTThis study aimed to verify the outcomesof the soil previously treated with aromatic plants in the germination and early seedling growth of lettuce var. Simpson under greenhouse conditions. The trial was developed at Embrapa Vegetables, in Brasília, Brazil in a completely randomized design with three replications and composed by eleven treatments as follow: soil cultivated with apple-mint (Mentha x villosa), wild mint (Mentha arvensis), peppermint (Mentha piperita), Mentha spp., citronella (Cymbopogon winterianus), lemon grass (Cymbopogoncitratus), basil (Ocimum basilicum), african basil (Ocimum gratissimun), thyme (Thymus vulgaris), sage (Salvia officinalis) and soil from the same area without prior cultivation of aromatic plant (control). The emergence velocity index (IVE), the survival rate (SR), the number of leaves (NL), the length of the main root (CRP) and the shoot (CPA), the fresh mass of the root (MFR) and the shoot (MFPA) and the dry mass of the root (MSR) and the shoot (MSPA), were evaluated 30 days after the sowing. The data were submitted to analysis of variance and Tukey's test at 5% probability. There was a significant difference regarding the IVE, in which the treatment with C.citratus negatively affected seedlingappearance. The treatment with M. arvensis showeda TS of only 16%at 30 days after the sowing. The NF was lower in the treatment with M. arvensis, differently from all the others, excepting the cultivation withS. officinalis. The MFR and the MFPA were stimulated by the treatment with T. vulgaris, which was higher than all the other cultivations. The obtained results showed that M. arvensis had a negative influence,while T.vulgaris presented a positive outcome in the early development of lettuce seedlings.

Outside its centers of origin, garlic propagates only asexually. Since asexual reproduction leads to the absence of meiotic recombination, the main garlic cultivars available for cultivation have arisen from the accumulation of somatic mutations in early cultivars. Thus, it is common for a single clone to have different names in different regions. This study aimed to evaluate the genetic diversity of 20 garlic cultivars by using morphological characters and amplified fragment length polymorphism (AFLP) markers to identify possible duplicate cultivars. We assessed 28 morphological characters related to the leaves, bulbs, and bulbils of the garlic plant and divided them into two categories: quantitative and qualitative (14 characters each). For molecular marker-based analysis, we used three AFLP primer combinations. Genetic divergence was calculated using the Jaccard coefficient; the cultivars were grouped using unweighted pair-group mean analysis. The average genetic divergence detected using the morphological characters was 2.30 (range, 0.45-4.70). Plant height and coat adhesion exhibited the highest divergence among the cultivars. The average genetic diversity based on AFLP data was 43% (range, 0-79%). Dendrograms derived from both techniques divided the cultivars into two groups: noble and semi-noble. Together with the divergence within groups, the correlation between morphological and molecular data suggested that the cultivars in the noble group had greater phenotypic stability than those in the semi-noble group. Analysis of Jonas and Quiteria cultivars using these two techniques revealed only slight differences, suggesting that these cultivars may be clones or have a high degree of kinship.
