Abstract

                                The study of genotypic, phenotypic and environmental correlations between yield and yield and components of soybean (Glycine max (L) merr.) revealed that seed yield per plant possesses highly significant possitive associations with plant height, pods per plant, and days to flowering, seeds per plant, branches per plant, and days to maturity. The characters which showed significant positive correlation with yield were also positively associated among themselves, except days to maturity with seeds per plant. A weaker positive or negative associations among the characters at environmental level were observed.

Key words : Soybean, Phenotypic, genotypic and environmental correlation, plant breeding
