Abstract

The present investigation was carried out during the winter seasons of 2013-2014 and 2014-2015 under field conditions at Sabahya Horticultural Research Station, Alexandria Governorate, Egypt. Plant materials for this study were consisted of 4 parents and 5 second generations, produced from self pollination F2, from five crosses occurred among four cultivars of  broad bean (Vicia faba L).The obtained results reflected, generally, all genotypes were showed highly significant differences for all the studied characters. This concept indicated that the evaluated populations differed in their genetic potential with respect to these traits. The mean squares for the parents F2 and PvsF2were significant for most of the studied characters. The obtained data, showed that the parent p1; gave the highest mean values for the following traits: flowering date (day), plant height (cm), pod length (cm), pod weight (gm, number of seeds/pod and seeds weight per pod (g). Heritability estimates were high in flowering date (days), fruiting date (days), height of the first flowering nod (cm), number of branches / plant, pod weight (gm), number of seeds / pod, seeds weight / pod (gm), number of pods / plant and total seeds yield / plant. The relationships were significant and positive between flowering date and fruiting date (days), height of the first flowering nod (cm), height of the first flowering pod(cm), number of pods / plant, and total fresh  yield / plant which affect on  total yield of broad bean. Regarding path analysis the direct effect of Flowering date (days) date, height of the first flowering pod (cm), plant height (cm) and number of branches / plant seemed to be close to correlations between them and seed yield so, it may indicate a true relationship and direct selection through these traits may be effective for improving seed yield of faba bean.
