In the present investigation, twenty two elite breeding lines of black seeded soybean [Glycine max (L.) Merrill] were evaluated for 14 agro morphological traits during Kharif 2012 season. Among qualitative traits, presence of multifoliate leaf type was observed only in lines having moderate to high hundred seed weight and presence of anthocyanin pigment on hypocotyl was found related to violet flower colour in black seeded soybean lines. Among quantitative traits, grain yield per plant showed highly significant positive phenotypic and genotypic correlation with traits viz., dry matter weight per plant (0.95& 1.0) followed by 100 seed weight (0.75 & 0.87) and number of pods per plant (0.52 & 0.50). Path coefficient analysis also confirmed that traits viz., dry matter weight per plant and 100 seeds weight along with days to maturity can be considered as the key traits that can play a crucial role in the genetic improvement of black seeded soybean (bhat) genotypes for Uttarakhand hills.
