Inter characters relationship in Indian mustard (Brassica juncea L. czern and coss)

The present investigation consisting a set in a fashion of half diallel cross combinations were carried out to investigate the inter characters relationship for fifteen characters in Indian mustard (Brassica juncea L. Czern & Coss) at Oilseed Research Farm, Kalyanpur of Chandra Shekhar Azad University of Agriculture & Technology, Kanpur under during rabi, 2018-19. The observations were recorded for days to 50% flowering, days to maturity, plant height (cm), length of main raceme (cm), leaf area index, number of primary branches per plant, number of secondary branches per plant, number of siliquae per plant, number of seeds per siliqua, biological yield per plant (g), 1000-seeds weight (g), harvest index (%), oil content (%), protein content (%) and yield per plant (g). The analysis of variance revealed highly significant mean sum of square for almost all the characters and correlation coefficient analysis reflected positive and highly significant correlation of seed yield per plant (g) with all characters except protein content (non-significant and positive correlation). Resultant direct selection for these traits would be effective for further yield improvement in given genotype of Indian mustard.
