| To evaluate the morpho-physiological characteristics and to investigate the effect of some growth indices as well as the light extinction coefficient on the grain yield and its components in common beans, a filed experiment was conducted with 46 promising lines of white bean and two improved check cultivars “Dehghan” and “Daneshkadeh” at the research field of Karaj, Seed and Plant Improvement Institute, Iran, in 2008 growing season. The experiment was performed as a randomized complete block design with three replications. Results showed significant differences among white bean genotypes for measured characteristics. Leaf area index and leaf area duration had positive and significant correlation with the grain yield, however, the correlation of light extinction coefficient with grain yield was not significant. There were positive and significant relationship between number of grain.plant-1, biological yield and number of pod.plant-1 with grain yield. Genotypes 4.1, 7.1 and 6.7 were identified as highly productive genotypes with grain yield of 1163.1, 1160.2 and 1154.4 (g.m-2), respectively. Genotype 4.1 had the highest leaf area index, leaf area duration and biological yield as compared with other genotypes. It is concluded that increasing grain yield in common bean can be achieved through improving the morpho-physiological characteristics. |
