Background: Tomato is commonly treated as "Protective Food" as it contain high amounts of several nutritive compounds especially carotenoids such as lycopene and â carotene (Provitamin A), flavonoids, phenolic acids and ascorbic acid and minerals like calcium, iron and phosphorus. Development of high yielding varieties, genetic improvement and best selection are the basic outcome of a superior breeding programme. Therefore, a study was conducted out to analyze the combining ability for yield and yield contributing traits of tomato genotypes. Methods: This study analyzed the general combing ability (GCA) and specific combing ability (SCA) of tomato (Lycopersicon esculantum Mill.) including different breeding lines and landraces, which were grown during three seasons (March 2020, September 2020 and March 2021) with row to row and plant to plant spacing of 60 x 45 cm in randomized block designs (RBD) having three replications at the Agriculture research farm of Choudhary Chhotu Ram (PG) College, Muzaffarnagar U.P, India. Morpho-metric data were recorded on five competitive randomly selected plants in each line for sixteen traits. Result: Number of fruit per plant and fruits yield was governed by non-additive gene action suggesting the advancement of the generation for selection to improve these traits. The parents floradade, arka meghali and EC-164563 were estimated to be best combiners for the inclusion in further breeding programs. The cross EC-620406 x EC-528360, a product of good combiners was best performing and can be used to obtain superior recombinants. [ABSTRACT FROM AUTHOR]

Background: Brinjal is one of the most popular and important vegetable crops grown throughout the year in India and other parts of the world. Though a large number of brinjal genotypes are available in India, only a few have good quality and yield during kharif. Therefore, the current study was carried out to identify and/or superior varieties with high yield and better quality brinjal during kharif, 2017-2018 consisted of thirty brinjal genotypes obtained from different places of India. Methods: All the genotypes were evaluated for fifteen morphological and six biochemical characters viz., plant height (cm), plant spread (cm), number of primary branches per plant, leaf blade length (cm), leaf blade width (cm), number of leaf prickles, days to first flowering (days), days to 50% flowering (days), fruit pedicel length (cm), fruit length (cm), fruit circumference (cm), number of fruits per plant, fruit weight (g), fruit yield per plant (kg), fruit yield per hectare (t), moisture content (%, FW), crude fiber content (%, DW), crude protein content (%, DW), ascorbic acid (mg/100g FW), solasodine content (mg/100g DW) and total phenol content (mg GAE/g FW). Result: Mean performance of brinjal genotypes revealed significant variation for morpho-biochemical characters. This variation may be due to the effect of genotype, environment or their interaction. Morphological characters of brinjal genotypes revealed that among the thirty genotypes, eighteen genotypes viz., Kuchia, Brinjal-3, Khoruah-1, Brinjal-6, Brinjal-8, Brinjal-4, Seujia Bengena, Brinjal-1, Brinjal-9, Brinjal-2, Brinjal Long, Green Long, Boga Bengena, Kajala, Sagolishingia, Long Khoruah, Brinjal-7 and Koni Bengena were found to be the superior performers for fruits/plant, primary branches per plant, days to first flowering, days to 50% flowering and fruit yield during kharif. The mean performance for biochemical characters also revealed wide variability among the genotypes in respect to quality performance. [ABSTRACT FROM AUTHOR]

Background: The South Gujarat hilly part is considered to be a non-traditional area of strawberry cultivation in India. The poor farmers of this region are cultivating strawberries under open field condition. Both, the yield and quality of strawberry fruits of this region are not up-to-the-mark as there in other parts of the country. Hence, a low-cost improved production technology is required to maximize yield as well as improve the quality of strawberry fruits. Methods: Uniform runners of strawberry cv. Winter Dawn were grown in open field under paddy straw as bedding material. Foliar spraying of plant growth regulators viz. NAA (50, 75, 100 and 125 mg l -1) and GA3 (50, 75, 100 and 125 mg l -1) were done at 30 and 60 days after planting. The experiment was laid out in randomized block design with control plants receiving no spray treatments and replicated thrice. Result: The plant growth parameters like plant spread, number of leaves, number of crowns, leaf area, length of petiole, number of runners were recorded maximum with the application of 100 mg l -1 GA3. This treatment was also found to be the best in respect of number of flowers, number of fruits, fruit weight, marketable and total fruit yield of strawberry. Strawberry fruits with the highest total soluble solid, ascorbic acid, reducing sugar, non-reducing sugar and total sugar content were recorded in the plants which received 125 mg l-1 NAA. However, the plant growth regulator treatments failed to influence any significant effect on days taken to 50.0 % flowering, fruit firmness and acidity content of strawberry fruits.
