REACCIÓN DE GERMOPLASMA DE SOYA A Phakopsora pachyrhizi EN CAMPO

Abstract

La roya asiática (Phakopsora pachyrhizi) de la soya (Glycine max (L.) Merr.), hizo su aparición en 2005 en México. Las variedades comerciales comúnmente sembradas han mostrado susceptibilidad al patógeno, por lo que el presente estudio tuvo el objetivo buscar fuentes de resistencia genética a la enfermedad, a través de la reacción de 197 genotipos de soya evaluados en campo. Se establecieron dos fechas de siembra (24 de febrero y 24 de abril, 2007) y las inoculaciones se hicieron a inicio de la floración. La severidad se evaluó en la etapa R6, mediante una escala de 1(0 %) a 3 (> 30 %). Se identificaron 23 genotipos de soya resistentes a P. pachyrhizi, en ambas fechas de siembra, los cuales no exhibieron lesiones foliares.
