Soybean is economically the most important bean in the world, providing vegetable protein for millions of the people and ingredients for hundreds of chemical products. 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 this cross 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, the highest proportion of transgressive segregants were recorded for grain yield per plant (24) followed by number of seeds per pod (26), 100-grain weight (25), plant height (23), number of primary branches per plant (9) and number of pods per plant (8).The most promising transgressive segregants observed in F2 generation were Plant No 64, which yielded 119.17% more grain yield than increasing parent. Phenotypic correlation of grain yield per plant with nine other characters studied in F2 generation of this cross indicated, significant and positive correlations with 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. These observations indicated that, the improvement in grain yield of soybean appears to be possible by making selection through these characters.
