Abstract

Fifty-seven tuber-bearingSolanum progenies including species and interspecific hybrid derivatives were evaluated for resistance to green peach aphid (GPA),Myzus persicae (Sulzer), using an excised leaflet test. The progenies segregated for resistance and most contained some highly resistant clones. Resistance appeared to be partially dominant and genotype-environment interaction was low. Heritability estimates of 50–60 percent were obtained from both diploid and tetraploid populations.

Resumen

Se evaluaron cincuenta y siete progenies deSolanum tubeŕiferos incluyendo híbridos intra e interespecíficos, por resistencia al áfidoMyzus persicae (Sulzer), usando una prueba de foliolos amputados. Las progenies segregaron por resistencia y la mayoría de ellas conteńian algunos clones altamente resistentes. La resistencia pareció ser parcialmente dominante y la interacción genotipo por ambiente fue baja. Se obtuvieron estimados de heredabilidad de 50 – 60% en las poblaciones diploides y tetraploides.
