Abstract

Drought is a threaded factor in world produce and application of breeding method is proposal for selection of tolerant and adapted cultivators under DROUGHT STRESS. In order to calculated of correlation coefficient and PATH ANALYSIS some traits that relationship with grain yield in 15 genotypes of CHITI BEANs under non-stress and DROUGHT STRESS conditions were studied using randomized complete block design with three replications in experimental field, Faculty of Karaj Agricultural in 2004 crossing season. Irrigation was each seven days and each ten days on non-stress and DROUGHT STRESS conditions respectively. In this experiment were measured some of traits such as physiological characteristics (date to flowering, filling duration and seed maturity), morphological seed traits (length, weight and seed diameter) and quantitative traits (No. seed/pod per plant, 100 seed weight and pod weight ). By stepwise regression introduced best model for two conditions. In regression model pod weight was the first trait that had highest R2 coefficient (R2=0.919) but second trait had lowest share under non-stress and DROUGHT STRESS conditions. Results of simple PHENOTYPICAL CORRELATION showed pod weight had highest correlation with seed yield on non-stress and DROUGHT STRESS conditions in 1% probability (r=0.95) and this result confirmed regression model. PATH ANALYSIS In non-stress condition showed greatest direct effect by weight pod (r=1.035) and days to 50% flowering (r= -0.201) respectively. PATH ANALYSIS In stress condition showed greatest direct effect by weight pod (r= 0.902) and number of seed per pod (r= 0.159). Total results showed for breeding programs, it is better that weight pod selected in CHITI BEAN. Also protein percentage not alternative trait under DROUGHT STRESS in CHITI BEANs.
