Abstract

To study seed yield and some associated characteristics in bean under DROUGHT STRESS condition an experiment was conducted in Mashhad Agricultural Reasech Station. Fifteen genotypes of beans were evaluated in two separate RCB design with 3 replications under stress and non-stress conditions. Analysis of variance showed that there were significant differences among varieties in terms of traits under study, indicating the existence of genetic variation among varieties. Heritability, genotypic and phenotypic coefficients of variation were determined. Most of the measured traits had significant phenotypic coefficient of variation. The results indicated that seed yield, number of seed per plant, biological yield and number of pod in Pinto been reduce under condition of stress whereas. In non-stress condition, yield was highly correlated with the number of pod. Where as in stress condition it was highly correlated with harvest index. FACTOR ANALYSIS were accomplished in non stress and water stress conditions. There were 4 factors that explained 76 percent in non stress condition and more than 69 percent of total variations in stress condition. Results of STEPWISE REGRESSION and PATH ANALYSIS showed that selection can be done based on number of pod per plant, harvest index, biological yield, 100 grain weight. Results of PATH ANALYSIS showed that the highest direct effect, being positive, was related to biological yield in non stress and related to harvest index in stress conditions. In classification of genotypes based on phenotypic characteristics climates, using CLUSTER ANALYSIS (UPGMA), all genotypes classified in 5 separate groups in non stress and stress conditions.
