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.
