Abstract

In this study, powdery mildew susceptible parent TBU-43-1 and resistant parent PU-609-43 were crossed. Parents, F1, F2, B1 and B2 of cross TBU-43-1 × PU-609-43 were screened for powdery mildew disease incidence and PDI was worked out. On the basis of PDI, plants were classified into two classes i.e., susceptible and resistant. The F1 showed susceptible reaction to powdery mildew. The segregating F2 population displayed the segregation in 3:1 ratio for susceptible and resistant reaction to powdery mildew disease. The segregation of F2 generation for powdery mildew disease reaction was confirmed in backcross generation. Also the Chi-square test indicated that the 3:1 ratio was perfectly fit for the susceptible and resistant reaction for powdery mildew disease. Thus, the current investigation revealed that a monogenic recessive gene controls powdery mildew resistance.

Conclusion

To summerize, the current research conclude that the segregation of resistance to powdery mildew disease of a blackgram cross TBU-43-1 × PU-609-43 follows the monogenic ratio. These results may be helpful in the development of breeding techniques to increase disease resistance as well as to understand the resistant of blackgram to the powdery mildew disease. The result above suggests that expression of blackgram's resistance to powdery mildew disease is controlled by a single recessive gene. Recombination breeding or immediate selection would be preffered to increase resistance in blackgram for powdery mildew
