Variability, Correlation and Path Coefficient Analysis of Yield and Some Yield Components in Faba Bean (Vicia faba L.) Populations


Abstract in English

In a study conducted at Research Center of Dara'a, General Commission for Scientific Agricultural Research during two growth seasons 2007/2008 and 2008/2009. 11 faba bean (Vicia faba L.) populations were planted in an experiment designed randomized complete blocks design with three replications. The objectives were investigation of phenotypic variance among populations studied, to determine the relationship among number of yielded branches plant -1, number of pods plant -1 , number of seeds pod -1, 10- green pod weight (g) and yield of green pods plant -1 (g) using correlation and path coefficient analysis. The combined analysis of variance showed highly significant differences among populations under study and for all characteristics studied, except number of yielded branches plant-1 where differences were only significant. The correlation and path analysis studies revealed that negative and highly significant relationship was found between number of yielded branches plant -1 and yield of green pods plant-1, while was positive and highly significant between yield of green pods plant-1 and 10-green pod weight. All direct effects of components studied were negative in both seasons, except 10-green pod weight, and these results suggested adopting the last component as a selection index during making selection of high yielding genotypes in faba bean populations. .
