| Abstract | ||
| A Study was conducted to establishing selection indexes for genotypes of soybean . The seeds of these genotypes were planted in two dates , first was at 20/5/2014 and the second was at 11/5/2015 using RCBD design with three replicates . to study ; plant height , number of the branchs , number of the leaves , number of the pods, number of the seeds in the pod, weight of the seed, plant yidd rate , total yield , oil and protein contenttraits . The results showed that the genotypes were different from all studied traits , the genotype (Eman) was surpassed in seed yield (3050 kg/h), number of pods (166.6 pod/plant) plant yield rate (51.5 gm.)and Protein content (35.4%) traits, for the first time , the genotype (Eman) was surpassed in seed yield (3540 kg/h),seed weight(182.6 mgm), plant yield rate (70 gm.) and oil content (23.9%) traits. Significant values have appeared for the genetic variance of the genotypes for all studied traits and for the two dates. Heritability values with broad sense were high in all the traits and for the two date, als the value of expected genetic advance were high as apercetage in the traits : seed yield for the two dates (691.6 and 827.85) res pectively , and the number of the pods (42.68) for the two date . Highly relative efficiency has appeared for selection index which included the traits the seed yield, number of the pods ,trait seed weight , (144.22) , and the selection index which included the traits the yield, trait seed weight , number of the branchs (114.49) and the selection which included the traits the seed yield, number of the pods, seed weight and number of the branchs (341.38) for the date .1 | ||
