Abstract : The photoperiodic response of soybean [Glycine max (L) Merr.] is a major factor determining the latitude and the sowing date at which soybean cultivars are grewn. In order to elucidate the effect of sowing date on phenotypic performance and stability of soybean, 16 genotypes of diverse origin were grown in three different seasons: summer, fall and winter in a randomized complete block design experiment with three replications. Data recorded on days to 50% flowering, plant height, seed size, harvest index (HI) and seed yield in each season as well as over the three seasons were analyzed and the different variance components were obtained, Stability parameters were also estimated for seed yield and HI. Sowing date effects and sowing date-genotype interactions were found to be highly significant for all traits mean while genotype effects were found to be significant for plant height and 100 seed weight. Seed yield showed to be more stable than HI and this could be due to the dependence of seed yield on diverse source of assimilates. November sown cultivars had moderate HI but they were significantly shorter, and had significantly larger seed size and higher seed yield than May and September sown cultivars. Cultivars Jupiter, ICAL 124 and Alamo proved to be stable and are considered to be best suited for the region.
