Online resources: Summary: Se discuten los factores que influyen en la evaluacion de resistencia a Empoasca: el tamano de la parcela; la interaccion estacion-genotipo o el alto nivel de varianza genetica no aditiva; caracteres agronomicos como el calor de las flores y las semillas, el habito de crecimiento, el vigor o habilidad para producir nuevas hojas. Se indica que la seleccion recurrente con una evaluacion de progenie es una buena metodologia para utilizar, aunque no se ha analizado aun el experimento que mide el avance genetico producido por esta metodologia. (CIAT)Summary: Factors that influence the evaluation of resistance to Empoasca are discussed: plot size, genotype season interaction or the high level of nonadditive genetic variance, agronomic characters such as the color of the flowers and seeds, growth habit, and vigor or ability to produce new leaves. Recurrent selection with a progeny test is suggested as a good methodology to use, even though the expt that measures the genetic advance produced by it has not yet been analyzed. (CIAT)
