Abstract:
White rust, caused by Albugo candida (Pers. ex Lev.) Kuntze, is the most prevalent and extremely destructive disease of B. juncea. The present study was carried out to evaluate Brassica juncea genotypes for resistance to white rust. Experimental material comprised of ninety genotypes of Indian and East European gene pool. White rust resistant genotypes viz. Heera and Donskaja and and susceptible genotypes RSPR 01 and Varuna were used as check genotypes. Out of ninety genotypes, three genotypes namely Donskaja IV, Domo and Cutlass showed no infection and they were considered as immune against white rust. Fifteen genotypes showed highly resistant response, twenty nine genotypes were found resistant, twenty four genotypes were observed as moderately resistant, nineteen genotypes were susceptible and none of the genotypes was found in highly susceptible category. Genotypes with immune and highly resistant genotypes can be further utilised for future breeding programmes for the improvement of this trait.
