Genetics of powdery mildew disease resistance in blackgram [Vigna mungo (L.) Hepper]
Powdery mildew susceptible (VBN 11) and resistant (LBG 17) blackgram genotypes were crossed. Parents, F1, F2, F3, F4 and BC1F2 of cross VBN 11 X LBG 17 were screened against powdery mildew disease. Based on the per cent disease index (PDI), two phenotypic classes were formed as resistant and suscep...

description | Powdery mildew susceptible (VBN 11) and resistant (LBG 17) blackgram genotypes were crossed. Parents, F1, F2, F3, F4 and BC1F2 of cross VBN 11 X LBG 17 were screened against powdery mildew disease. Based on the per cent disease index (PDI), two phenotypic classes were formed as resistant and susceptible. The F1 showed susceptible reaction to powdery mildew disease. The segregating population in F2, F3, F4 and BC1F2 segregated in 3:1 ratio for susceptible and resistant reaction to powdery mildew disease. The Chi-square test indicated that the 3:1 ratio was perfectly fit for the susceptible and resistant reaction for powdery mildew disease in all segregating populations. Hence, the present study confirmed that the resistance of powdery mildew resistance is governed by a monogenic recessive gene.
