Sorghum is the third most important cereal crop in India and, over both the rainy (kharif) and the Post-rainy (rabi) seasons, totals a combined area of more than 11 million ha. Rabí sorghum is important for both food and fodder in the drought-prone areas of the states of Maharashtra (3.3 million ...
In recent years cassava has become an important raw material for various domestic needs (food, feed, alcohol and high fructose sugar). To cope with high demand for cassava roots the breeding and selection program has been intensified to identify varieties that are high yielding and having high st...

Recent progress in cassava varietal improvement in the Philippines
Since considerable progress has been made in the yielding ability and disease resistance through single-trait selection of cassava material for HI, branching type, or resistance to CBB (Xanthomonas campestris pv. manihotis) and superelongation [Sphaceloma (Elsinoe) manihoticola], emphasis in sele...
Debido a que se han obtenido considerales progresos en la capacidad de rendimiento y en la resistencia a enfermedades mediante la seleccion de materiales de yuca por sus caracteristicas individuales en relacion con IC, tipo de ramificacion o resistencia a CBB (Xanthomonas capestris pv. manihotis)...

International nurseries are a good source of genetic variability since they include collections of native, introduced, or improved materials. Observation and yield trials are performed to select materials; in the former, undesirable materials are discarded and the latter include an exptl. design ...
Los viveros internacionales representan una buena fuente de variabilidad genetica, ya que cuentan con colecciones de materiales nativos, introducidos o mejorados. Para seleccionar material se realizan ensayos de observacion en donde se descartan los materiales indeseables, ensayos de rendimiento,...
