Abstract: In a study of inheritance of powdery mildew resistance, two parents, their reciprocal crosses, F₂, B₁ and B₂ of both crosses were screened against powdery mildew. There were no significant difference between the F₁ of Kopergaon x BPMR-145 and it’s reciprocal cross for powdery mildew susceptibility, indicating that the resistance is governed by recessive gene and also absence of maternal inheritance for powdery mildew resistance. The F₂ data of both crosses i.e. Kopergaon x BPMR-145 and BPMR-145 × Kopergaon was good fitted in 3:1 (susceptible: moderately resistant) ratio which indicated the involvement of single recessive gene which confirmed from backcrosses data. The moderately resistant plants identified for powdery mildew in F₂ should be utilized for development of powdery mildew resistant variety in mung bean. There is need to develop complete resistant donar to powdery mildew disease.
