Inheritance of Resistance to Cercospora Leaf Spot in Mungbean

Abstract

Genetic studies on the resistance to cercospora leaf spot and some other quantitative traits in 45F1s deriving from diallel crosses of 10 mungbean varieties indicated that additive gene action was the mode of inheritance for cercospora leaf spot resistance, 100-seed weight, plant height and number of pods per plant. While the inheritance of days to frist flower, days to first ripe pod , days to maturity and yield per plant were governed by dominant gene action. Broad sense and narrow sense heritability of the resistance to cercospora leaf spot were about 99 and 75 percent , respectively
