nuevos cultivares en la Empresa Azucarera “5 de septiembre”, el objetivo general consistió en realizar el estudio de B80250, C86-156 y C97-445, para mejorar la estructura de dichos cultivares. El experimento se estableció en marzo de 2021 en la localidad La Julia (N 22º 25' 2,2064” W -80º 30’ 1,152”), suelo Pardo con carbonatos y las evaluaciones correspondieron a la cosecha de planta con 12 meses, en las que se tuvo en cuenta el rendimiento agrícola, contenido azucarero y otros indicadores de la eficiencia industrial. Quedó corroborado que C97-445 y C86-156 por sus potenciales agroindustriales y seguridad fitosanitaria, pueden ser la solución de la riesgosa explotación actual de C86-12 y C90-469. Se recomienda dar continuidad al trabajo en otras cosechas y a partir de la experiencia implementar estudios similares con otros cultivares y ambientes. El enfoque teórico asumido es de carácter cuantitativo, con el empleo de una metodología experimental y se dan a conocer los resultados de la investigación.

El comportamiento del cultivar C86-12 se validó en la Unidad Básica de Producción Cooperativa “La Josefa”, de la provincia Cienfuegos. Se consideraron los resultados cinco cosechas, la dinámica de maduración desde noviembre hasta abril y el monitoreo fitosanitario de roya, carbón y el virus del amarillamiento foliar, respecto al control C1051-73; de dos experimentos de primavera de ciclo largo y frío, que se tuvieron en cuenta en la fase de discusión participativa de la propuesta del Servicio de Variedades y Semilla. Se emplearon técnicas estadísticas de análisis de varianza, comparación múltiple de medias y regresión polinómica de segundo orden, en el procesamiento de los datos. Se corroboró que C86-12 posee las cualidades en cuanto a rendimiento agrícola, azucarero, maduración temprana y seguridad fitosanitaria para contribuir a la preservación de C1051-73, mediante su reemplazo en los agroecosistemas de mayor vulnerabilidad y riesgo al virus del amarillamiento foliar, por lo que se proyectó un incremento de desarrollo hasta el año 2022, para ubicarse como la segunda variedad en importancia en dicha unidad.

The orange rust of the sugar cane [Puccinia kuehnii (W. Krüger) E. J. Butler], is a disease of potential danger for the sugar industry in Cuba. The objective of the research was to determine the spatial distribution of orange rust in leaves infected by P. kuehnii, type of distribution of the pustules and the possible use of a quantitative variable that allows estimating the affected leaf area with a superior precision to observation of the human eye. From the cultivar C01-227 (susceptible to the disease), 25 leaves were collected and the +5 leaf was selected. The type of spatial distribution of the pustules was determined by calculating the variance / mean ratio and the Morisita index. A maximum of 6.88 pustules per cm2 was determined in leaves with 25% of affected leaf area and an average of 2.26 in leaves with affectation from 5 to 25%. The pustules for square centimeters was significantly higher in the middle and apical thirds; but in the third of the leaf, their value average or their maximum is not related directly with area affected in the leaf.

In this paper the results of a study conducted over five years (2006-2010) with the objective of determining agroecological zones occur handle (Manguifera indica L.) in Unit Fruit of Cienfuegos, in order to optimize the production process culture and make more efficient use with the genotype-environment interaction. Three varieties (Chino, Haden and Super Haden), replicated in environments that formed the combination of three units with five years were used. The rains were more discriminating power of agroecological zones soil variables, mainly dry period, determining the existence of two areas; one consisting of the unit three lower yield potential and another for the remaining two units, which can contribute to the efficiency of production management if a pattern is followed by specific site. The investigation also found that there is significant interaction between cultivars and environments, suggesting that these results are used in the use of genotypes according to their stability and adaptability.

At present, it is necessary to obtain new sugarcane cultivars with high sugar potential and adapted to several harvest cycles, so the present work aimed to show the agro-sugar characterization of the new cultivar ‘C90-167’, obtained and recommended by Estación Territorial de Investigaciones de la Caña de Azúcar de Villa Clara, belonging to Instituto de Investigaciones de la Caña de Azúcar, for its commercial exploitation. This cultivar went through the selection scheme of the genetic improvement program of the breeding institution, from the initial stages of posture lots, clonal lots and replicated experiments. The cultivar ‘C90-167’ stands out for its high agricultural yield and satisfactory sugar content in relation to the control cultivars ‘C86-12’ and ‘C1051-73’. It is necessary to emphasize, as an important attribute, the resistance presented in artificial foci of infection to the main pests and diseases of economic importance of the crop. It is recommended for planting in both long spring and cold cycles in carbonate-padded brown soils. [ABSTRACT FROM AUTHOR]

The authors present case studies of patients with genital leakage that are linked to patent peritoneovaginal duct and polycysctic kidney diseases. They state that a 76-year-old man with stage 4 chronic kidney disease (CKD) has been inserted with a peritoneal catheter for open surgery. The authors note that a 45-year-old man with stage 5 CKD has underwent renal replacement therapy.

The aim of this work was to design and establish a model of macro data management to facilitate decision-making in the Sugarcane Breeding Program in Cuba and increase its efficiency. For this, available sources of information from the selection process from the period 2000 to 2017 and those coming from the agroproductive response of cultivars in production areas were used. A model was designed and applied that includes components such as: infrastructure, collection, validation, storage, processing, analysis and visualization. A case study of the C86-12 x CP70-1133 cross was conducted to characterize its selection background. As a result, the big data approach made it possible to obtain a compilation of primary data and selection results, estimate the genetic value of parents and crosses, classify the crosses and facilitate decision-making in the sugarcane breeding program in Cuba to obtain new commercial cultivars. Its application in the case study guaranteed access to all available information on the subject and recommending its best management. [ABSTRACT FROM AUTHOR]
