Abstract: During present investigation 12 yield contributing characters of twelve species/ varieties of Indian mustard (Brassica juncea L. Czern & Coss) were studied. Twelve yielding contributing characters were days to 50% flowering, plant height (cm), primary branches/plant, secondary branches/plant, days to maturity, siliquae/plant, seeds/siliquae, biological yield (g)/plant, grain yield (g)/plant, harvest index (%), 1000 grain weight(g) and oil content (%). During rabi season 2013-14, set of parental lines were grown and made 66 crosses in 12 x 12 half diallel design with help of hand emasculation. The experiment was conducted at Crop Research Center (Chirodi Block) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) under timely sown conditions during rabi, 2014-15. The value of correlation coefficient at phenotypic level, grain yield per plant (g) was recorded with highly positive significant correlation with Biological yield and some other traits. Traits biological yield per plant was observed with highest direct effect on grain yield in followed by some other traits in both genotypic and phenotypic path analysis. Resultant direct selection for these traits would be effective for further yield improvement in given genotype of Indian mustard.
