Abstract:

In order to assay genetic diversity and to detect the most important effective agronomic traits on yield improvement in 9 cultivars of been, an experiment based on RCBD with 3 replication under after poding moisture stress condition was done. The cultivars showed the significant (p<0.01) difference for the majority of the studied traits, indicating a high level of genetic diversity among the genotypes. Pak and Daneshkaded showed the maximum and Goli and Sayad had the minimum grain yield, respectively. Pak and Daneshkade, with the highest yield, showed a high level of pod number per plant, pod number containing grain, biomass per area, pod weight per plant and branch number containing pod. Grain yield showed a significant and positive correlation with branch number containing pod, pod number per plant, pod number containing grain, pod weight per plant and biomass per area. Step wise regression indicated that the traits of biomass per area, pod number per plant, grain length, pod weight per plant, grain diameter and 100-grain weight were the most important and effective traits on grain yield improvement. Path analysis showed, the trait of pod number per plant had the highest direct effect and the trait of biomass per area showed the maximum indirect effect by pod number per plant on grain yield increment.

Keywords:

Genetic diversity, Grain yield, Correlation analysis, Step wise regression, Path analysis.
