Two field experiments were carried out in the Research and experimental Center of the Faculty of Agriculture at Moshtohor during 1995/96 and 1996/97 seasons. The aim of this study was to determine the effect of irrigation treatments ( one , two and three irrigations ) on four new pure lines of faba bean i.e ( Moshtohor 6,10,43and Shebeen El-Kom 5 as well as the commercial variety (Giza 461). The characters studied were plant height (cm), number of branches/ plant, number of pods/ plant , number of seeds / pod and plant, weight of pods/ plant (g) , weight of 100 seed (g), seed yield /plant(g) and seed yield / fed (kg).
All traits under study in both seasons as well as the combined analysis were significantly increased by the increase in number of irrigations except number of seeds/pod and number of branches/plant in the first and second seasons, respectively.
The differences between faba bean genotypes were significant for all the studied traits in the separate seasons as well as the combined analysis , except weight of pods/ plant in the first season , number of branches/ plant , number of seeds/pod and plant and drought susceptibility index (DSI) in the second season, number of branches/plant, number of seeds / pod and weight of pods/ plant in the combined analysis . Moshtohor 43 had the highest seed yield /fed over the two seasons and out-yielded Moshtohor 6,10,Shebeen 5 and Giza 461 by 10.05.8.99,3.74 and 5.44%, respectively .
Significant positive phenotypic correlation values were detected between seed yield /fed or plant and each of other traits .Seed yield /plant followed number of pods/ plant had a high and positive direct effect on seed yield /fed.
The direct effect of seed yield /plant followed by indirect effect of number of pod/plant through seed yield/plant at the combined analysis, these effects account for approximately 72.72 % of seed yield/fed variation.
