Abstract

glycine-maxAn experiment was conducted to evaluate variability and correlation among yield and yield related attributes in Soybean (Glycine max L). Ten accessions of soybean including two checks were used in this experiment. RCB designe was used with three replications. Data was recorded on eight traits including days to 50% flowering days maturity, plant height, number of pods plant-1, pod length, 100 seed weigh, seed yield ha-1 and oil contents (OC%). The analysis of variance revealed highly significant variation among the accessions for all the studied traits. Correlation analysis exhibited positive and significant correlation between seed yield days to 50% flowering, days to maturity, pods plant-1, 100 seed weight. Positive correlation was observed for seed yield with pod length. It showed negative correlation with plant height. Among the tested genotypes Elgin was high yielding with 3 tons ha-1 and LD-3309 was low yielding with 2.4 tons ha-1 dry seed production. In terms of maturity LD- 3309 was early while Elgin was late maturing type. The present study suggests that these genotypes may be further studied and included in breeding programs.
