Selection of suitable variety for an agro-climatic zone is of prime concern for soybean growers. Moreover, identification of suitable plant traits showing maximum contribution to final seeds yield is important for plant architects. Experiment was laid out in randomized complete block design (RCBD). Soybean variety LV19 showed best performance as it gave significantly higher plant height (36.48 cm), leaflet and leaf area (15.66 and 46 cm2), No. of branches per plant (6.66), No. of pods plant-1(79.66), biomass (83.45 g), Pods weight per plant (34.15 g), 100-seeds weight (9.3 g) and seeds yield per plant (25.66 g). Contrastingly, soybean variety LV88 was found to be inferior as it gave lowest value for most parameters. Seeds yield showed a significant positive relationship with leaflet are (R2=0.89), leaf area (R2=0.909), No. of branches per plant (R2=0.64), and plant biomass (R2=0.63), No. of pod per plant (R2=0.73) and pods weight (R2=0.73) where as non-significant negative relationship with plant height (R2=0.21) and 100-seeds weight (R2=0.44) was observed. The strongest relationship of seeds yield was seen with number of branches per plant (b=1.65) followed and the weakest with plant biomass (b=0.02). Therefore this traitshould be considered to be most important while selecting improved soybean genotypes under semi-arid conditions.
