Abstract

Effect of salinity on germination percentage, dry matter per plant, number of siliqua per plant, 1000-seed weight and seed yield per plant of Indian mustard [Brassica juncea (L.) Czern & Coss] was studied (2008-09 & 2009-10). Five genotypes (Urvashi, Basanti, Varuna, Rohini and Ashirwad) were evaluated at five levels of salinity viz. normal, 3, 6, 9 and 12 dSm-1. All the five mustard genotypes showed increasing trend with respect to all above mentioned crop parameters with 3 dSm-1 salinity over normal water, but further increase in irrigation water salinity above 3 dSm-1 reduced all parameters significantly with each increase in salinity upto 12 dSm-1. Among genotypes, Urvashi showed best performance with respect to above mentioned characters at higher levels of 6, 9 and 12 dSm-1 salinity, while Ashirwad performed poorest. Thus, Urvashi genotypes proved to be more tolerant to salinity than other genotypes.
