Indian mustard (Brassica juncea) is the most important and major edible oil seed crop. White rust [Albugo candida (Pers. Ex.Lev.) Kuntze] is the important disease which can cause major yield losses in Indian Mustard. This study shows comparative assessment of white rust disease index (%), white rust disease severity and white rust disease incidence on leaves as well as on the inflorescence in the improved varieties of Indian Mustard. The experiment was conducted in RBD in split plot arrangement with three replications. Nine different improved varieties of Indian Mustard (Brassica juncea) were used as main plots, while protected and unprotected treatments were considered in sub-plots separately. Per cent disease index (PDI) of white rust on leaves of different genotypes of Brassica juncea was recorded at four stages of plant growth i.e. 80 DAS, 90 DAS, 100 DAS and 110 DAS while staghead severity and staghead incidence were recorded one week before maturity. Brassica juncea, varieties PR-2006-14 and NDRE-4 found susceptible to white rust which shows maximum PDI (74.97) and 56.31 respectively while varieties PRB-2008-5, PRE-2009-12, and PRB-2004-3-4 found slightly tolerant to White rust disease and shows minimum PDI (52.15), (49.98) and (49.98) respectively.
