Reactions of mustard varieties / germplasms / advanced breeding lines against white rust in field under Konkan conditions

Abstract

In Konkan region of Maharashtra State, white rust disease has been emerging as a serious threat to mustard cultivation during winter season since, last few years. Considering economic importance of the disease, different mustard varieties / germplasms / advanced breeding lines were evaluated against white rust disease in field under Konkan conditions to find the resistant entries. All mustard varieties / germplasms / advanced breeding lines evaluated were found susceptible to white rust disease, under natural epiphytotics. Least disease severity was observed in Mutant variety with 26.66%, followed by JD-6 (27.40%), Geeta (27.41%), Urvashi (28.14%), ACN-9 (28.88%), GM- 2 (29.63%). The highest disease severity was observed in Pusa Bold with 41.48% disease severity.
