Online published on 2 January, 2017. Abstract The fungal pathogen Albugo candida is distributed worldwide and causes white rust disease of rapeseedmustard. The disease can be managed by the use of fungicides, resistant cultivars, agronomic practices and biotechnological methods. However, the use of resistant cultivars is the most economical and environment friendly method for the management of rapeseed-mustard. Therefore, in the present investigation 147 putative lines of Brassica spp. screened in infested field for Albugo candida. Out of 147 putative lines, twenty lines viz. M2P6, M2P-20 M2P-23, M2P-24, M2P-25, M2P-29, M2P-41, M2P-42, M2P-59, M2P-65, M2P-66, M2P-81, M2P-84, M2P-89, M2P-109, M2P-117, M2P-119, M2P-120, M2P128 and M2P-138 were found to be white rust disease resistant while one line M2P-30 was highly resistant. The results will be useful for selecting elite genotypes for disease resistance where white rust disease is prevalent. In addition, the resistant genotypes can serve as a gene pool used in breeding programme todevelop new resistant genotypes.
