Abstract
Water deficit caused reduction productivity attributes for faba bean crop. So, seven faba bean genotypes were evaluated as parents with their F1 crosses under normal and water stress at the Experimental Farm, Faculty of Agriculture, Benha University, Egypt, during the 2021 /2022 and 2022/2023 winter growing seasons to study heterosis, combining ability and genotype behavior across irrigation treatments. Highly significant differences mean squares due to genotypes, parents, crosses, parent vs crosses, GCA and SCA were detected for all traits in both and across trials, except number of branches plant-1 . Water stress caused reductions in plant height, number of branches plant-1 , number of pods plant-1 , weight of pods plant-1 , number of seeds pod-1, 100-seed weight, and seed yield plant-1 by 6.05, 9.86, 15.24, 11.06, 1.03 and 4.77%, respectively. GCA/SCA ratio values exceeding largely the unity were detected for number of branches plant-1 , number of pod-1 and seed yield plant-1 , in both and across irrigation treatment, indicating that largest part of the total genetic variability was due to additive and additive x additive gene effects. The cross P1xP5 recorded the highest significant and positive heterosis relative to mid parent and better parent being 40.65% and 40.27%. P5 (Sakha 4) and P5 (Sakha 4)xP6 (Wadi 1) exhibited the best general combiner and best specific effects for seed yield per plant, respectively.
