Ex. Lev.) Kuntze. (A. Cruciferarum S.F. Gray) is one of the major diseases, responsible in reducing the yield of Rapeseed-Mustard (Brassica sp.). The main objective of this study was planned to develop photographic disease assessment keys for White rust of Rapeseed-Mustard. However, till now only diagrammatic or numerical assessment keys have been reported for screening of Rapeseed-Mustard germplasm against White rust disease but none is available on the basis of their actual photographs. Materials and Methods: Disease severity was taken on transparent graph paper. Pictures of disease free cotyledons and leaf, less than 5, 5-10, 11-25, 26-50% and more than 50% area covered by white rust pustules were observed for assessment key. Results: Rapeseed-Mustard plants were screened from seedling to maturity stage against White rust disease. The rating scale was developed from original field photographs with all above ground parts of infected plant viz. cotyledons, pods and leaves. Conclusion: In present study, the key was prepared for assessment of disease severity at cotyledonary leaf stage, pod stage and true leaf stage of plant. This would be helpful for consistent assessment of white rust disease as well as other leaf spot disease of Brassica sp.]]>Berkenkamp, B. and K. Degenhardt,1972526263Petrie, G.A. and T.C.
