The present investigation represents an attempts to study: 1) type and relative amount of genetic variance components and their interaction with the environment; and 2) heterosis in some quantitative characters in faba bean (Vicia faba L.). For this purpose, a half diallel crossing was performed, including seven varieties which were evaluated in a completely randomized block design with three replications over two years. Significant years means squares were detected for all traits except chocolate spot and number of seeds per pod. Mean squares for genotypes, parents and hybrids were highly significant for all traits. Significant parents vs. hybrids mean squares were shown for all traits except disease resistance.
