Abstract: | Summary The nature and mode of inheritance of resistance to Helminthosporium maydis blight was investigated in two maize varieties, RbU-W and DIC . The study of F1, F2, and reciprocal backcross populations of crosses between these two varieties on the one hand and two susceptible varieties, UVE and ZPSc-58c on the other, revealed that resistance in the two varieties is monogenic recessive. The genes for resistance in the two varieties are allelic. Resistance was shown to be a lesion-type and measurements revealed that it operated through reduced lesion size and lesion number. |
