Abstract

Inheritance of resistance to powdery mildew (Erysiphe polygoni D.C.) was investigated using TARM 18 as moderatly resistant and JLM 5, KDM 21 and WGG 37 as susceptible parents of mungbean (Vigna radiata L. Wilczek). The F1s of the three crosses viz., JLM 5 x TARM 18, KDM 1xTARM 18 and TARM 18 x WGG 37 were observed to be susceptible to powdery mildew indicating that the susceptibility to this disease is dominant and resistance is recessive. The F2 generation of these three crosses were segregated into 63 susceptible:1 moderately resistance indicating involvement of three duplicate recessive genes for resistance. This ratio was confirmed through F3 segregation.
