Abstract

Inheritance of resistance to a Queensland isolate of ZYMV in Cucurbita ecuadorensis was investigated in a
glasshouse using C. maxima as susceptible parent (P1), C. ecuadorensis as resistant parent (P2), F1 , F2 ,
backcross and self-pollinated backcross populations. Major gene models did not fit all the data well but estimates of heritability were high (h2B = 97%; h2N = 90%), implying that selection of C. maxima genotypes with resistance to ZYMV should be efficient.
