The soybean or soya bean (glycine max L.) is a species of legume native to East Asia widely grown for its edible bean, which was numerous uses. The aim of this study was to identify the superior transgressive segregants and estimate the correlation coefficient between seed yield, and yield components. Six generation of three crosses were evaluated at Botany Section Farm, College of Agriculture, Dhule during Kharif, 2019. The field experiment was arranged in a randomized block design (RBD) with non-replicated fashion. In most of the transgressive segregants, the better parent yield was transgressed with transgression of one or several other characters. In general highest proportion of transgressive segregants were recorded for grain yield per plant (29), followed by plant height (26), 100-grain weight (24), number of pods per plant (14), number of seeds per pod (12) and number of primary branches (2). The most promising transgressive segregants observed in F2 generation of this cross was plant no. 475, which yielded 151.22% more than its increasing parents. Phenotypic correlation of grain yield per plant with nine other characters studied in F2 generation of this cross indicated, significant and positive correlations with three characters, viz., number of primary branches per plant, number of pods per plant, and number of seeds per pod. These characters also showed significant and positive correlation among themselves uniformly. From the above observations the improvement in grain yield of soybean appears to be possible by making selection through aforesaid characters.
