| Abstract | ||||
| The objective of this study was to estimate the correlation coefficients (genotypic and phenotypic) and carry out path analysis between grain yield and its primary components. The experiments, in randomized complete blocks with three replicates, were carried out at El-Baramoon Horticulture Research Farm, Dakahlia Governorate Egypt in the 2009 and 2010 growing seasons. Twelve common bean genotypes were assessed including advanced lines and commercial varieties. The correlation studies revealed that in general, estimates of genotypic correlation coefficient were higher than corresponding phenotypic correlation coefficient. Seed yield per plant showed positive and significant correlation with number of pods per plant, number of branches per plant and biomass yield per plant at genotypic and phenotypic levels. Negative and significant association was observed between number of pods per plant, pod length and 100 seed weight. The results suggested that these traits could be considered as major grain yield contributing characters in common bean. Number of pods per plant, 100 seed weight and number of seeds per pod exhibited maximum positive direct effect on grain yield plant, respectively. It indicated that these are main contributors towards yield. Based on results expressing characters association and path coefficients for yield and its contributing characters, breeders should give attention to the characters like number of pods per plant, number of seeds per pod, 100 seed weight and days to 50 percent flowering and making selection of high yielding genotypes in common bean. | ||||
