Abstract: The Oil Seed, Agriculture Research Centre, in Tando Jam, conducted the research experiment in March 2022.The RCBD research trials employed ten genotypes of soybean and included three replications.At the P<0.01 level of significance, the results showed that all genotypes' mean square analysis of variance was very strong for the following traits: germination percentage, days to 75% heading, days to 75% maturity, plant height cm, branches plant-1, pods plant-1, seed yield plant-1 (gm), and seed yield plot-1 (kg/ha).We found that BCI-4 and BCI-6 had taller plants, while BCI-5 had a shorter height.Falak Sher reached 75% maturity in 67.67 days, while ESB-390 and Falak Sher (415.67 and 414.67) demonstrated the highest seed yield in plot 1 and hectare 1. Plant 1 had more BCI-3, BC-5, and ESB-390 branches.However, the genotypes BC-2 and BC-3 showed greater pods in plant-1 (35.66 and 35.00, respectively).The character seed yield (Kg) observed a significant correlation with germination% and plant height (r = 0.339*) and (r = 0.359*).The character seed yield hectare-1 showed a significant correlation with the days to flowering and the number of branches per plant (r = 0.346*) and (r = 0.332*).The soybean genotypes displayed heritability estimates ranging from low to high for various characters.However, pod plant -1 displayed high heritability estimates of 95.48%, with a genetic advance of 44.39%.Seed yield per hectare wasalso found to have higher heritability estimates of 99.02%.Future breeding program can recommend ESP-390 and Falak Sher, the best genotypes that took fewer days to mature, for their higher seed yield per plot and per hectare.
