Abstract
The research was aimed to select the best genotypes according to their production performance and the characteristics associated with yield under the conditions of the eastern region of Aleppo. The plant material was planted with 74 Inbred lines and 4 local cultivars (Improved Municipal, Hama 2, Hama 3) and the Cypriot cultivar according to Randomized complete block design with three replications and studied the most important productive attributes and their correlation with yield and calculated the broad sense Heritability (h2B.s) and estimated the coefficients of phenotypic and genotypic correlation between the studied traits and yield, and the GGE Biplot was used to study the relationship between studied traits. The results showed significant differences between the genotypes for all the studied traits. The G24 genotype distinguished the highest value of the number of pods per plant (41) and the number of seeds per plant (259). G69 showed the highest value for the number of seed per pod (6) The genotype G37 recorded the highest value of seed weight per plant (94.3) and the genotype G9 was produced the highest yield (3777.8) compared with all studied genotypes Genetic variation was the highest for yield trait, and broad sense heritability was the highest value for both biological yield and seed weight per plant (99%). The genetic correlation was significant between most of the traits. The GGE Biplot analysis showed that the best genotype combines these traits was G24 .
