Abstract :
To evaluate the morphological characteristics, yield and yield components of soybean genotypes, an experiment in randomized complete block design with 3 replications were conducted in Parsabade Moghan in 2011-12. Genotypes were evaluated in this experiment Apollo, Zane, L.17, Williams, INA, Hsus-H116, Spry, Ks4895, Stress land, Rend, L.77-2061, Omaha, L.75-6141, Darby, NE3399, L.93-3312 and L.83-570. Plant height, distance between the first split, number of branches, number of pods, pod weight, seed weight, number of seed, thousand seed weight, grain yield, protein content and yield were evaluated. The results showed had significant differences in plant height, number of branches, pods and seeds per plant, pod weight, 1000 seed weight, grain and protein yield. Among genotypes, Darby had the highest number of branches per plant 6.55, number of pods per plant 119.89, weight of pods per plant 17.19 g, 1000 seed weight 29.49 g, number of seeds per plant 246.06, grain yield 72.5 kg ha-1 and protein yield 3316 kg ha-1. The highest protein percentage (50.75) were observed at L.75-6141 and maximum distance from the first branching (15.70 cm) per Ks4895 genotype. The Williams and Zane 16 genotypes also were has highest average plant height (103.33 cm) and seed weight (166.57 g). Cluster analysis of soybean genotypes classified into three groups, Group I, II and III, were in their place, 8, 5 and 4 respectively genotypes, in this between, second group (including Darby, Williams, Hsus-H116, Apollo, L.93-3312 genotypes) had a mean yield and quality traits than the other two groups.
