Abstract:
Forty eight genotypes were evaluated during kharif- 2021 using Pant U-30 and Kopergaon as resistant and susceptible checks respectively. Out of the 48 genotypes, 3 genotypes Pusa B-43, RVSTU 21-1 and Pant U-30 were found immune, two genotypes DKU 87 and PU 31 were resistant. Three varieties having different reactions against powdery mildew i.e., resistant, moderately resistant, and susceptible, were tested to see how recommended disease management practices (DMP) might affect the disease severity and yield. Our present investigation indicated that the powdery mildew disease can be effectively managed using resistant cultivar along with recommended management practices. The yield performance of the resistant/ moderately resistant cultivar will decide the cost benefit ratio.
