Validation of molecular marker associated with powdery mildew resistance in mungbean

Published on

Powdery mildew caused by Erysiphe polygoni, is one of
the major diseases of mungbean (Vigna radiata L. Wilczek),
causes yield loss up to 20-40%. The present investigation
was undertaken to study the SSR markers associated with
powdery mildew resistance in mungbean. The resistant
line, TARM1 was crossed with highly susceptible, but
popular variety DGGV2 and the F1s were selfed to obtain
F2. F2 population was evaluated for response to powdery
mildew under field conditions. Of the 64 SSR markers
studied, only four were found polymorphic between two
parents (TARM1 and DGGV2). Single marker analysis
indicated that one SSR marker (MB-SSR238) showed
association with powdery mildew resistance in mungbean,
explaining the phenotypic variance of 11.64%.
