Czern & Coss] is one among the foremost necessary oilseed crops of the country and it occupies significantly massive acerage among the Brassica group of oil seed crops. It is the second most important edible oilseed crop after soybean in the country. It contains adequate quantity of the 2 essential fatty acids, linoleic and linolenic which are not present in many of the other edible oils. At World level, rapeseed-mustard crops area unit full-grown in fifty three countries spreading over the six continents, covering a region of 22.33 million hectare with on average production of 33.17 million tonnes and an mean yield of 1468 kg/hectare ranging from 333 kg/hectare (Tazikistan) to 6667 kg/hectare (Algeria). India stands second in both acreage and Path coefficient analysis with correlation coefficient for yield and its element were conducted at analysis Farm Department of Genetics & Plant Breeding, Narendra Deva University of Agriculture and Technology, Faizabad (U.P.) throughout Rabi, 2011-12, on sixty four genotypes with four checks varieties (Vardan, Ashirwad, Kranti, and Maya) in Augmented Block Design. Information obtained by this method helps in direct and indirect selection for genetic improvement of yield. Results revealed that the seed yield plant -1 showed extremely vital and positive correlational statistics with length of main flower cluster, secondary branches plant -1 , primary branches plant -1 , plant height and siliquae on main flower cluster whereas non-significant positive correlation with remaining characters. Path analysis disclosed that characters viz., seed yield exhibited the highest positive direct impact on length of main flower cluster followed by primary branches plant -1 , secondary branches plant -1 and plant height. Considering each, the correlation co-efficients and path co-efficients along, length of main flower cluster, number of primary & secondary branches plant -1 and plant height emerged as vital elements of seed yield which should be given due importance during indirect selection criteria.
