and/or non-drought conditions.
Four methods (M1, was grown under drought in F3 and F4, M2, was grown under drought in F3 and non- drought in F4, M3, was grown under non-drought in F3 and drought in F4 and M4, was grown under non-drought in F3 and F4) were formed from each cross in F5and evaluated in two open field experiments (under drought and non-drought conditions).
The experiments were planted in split plot design with crosses in main plots and selection methods in sup plots.
Highly significant differences among crosses and methods and their interactions were reported by combined analysis of both environments.
Drought harmful faba bean traits and seed yield decreased from 53.5 to 74.4%.
Under drought stress, M1 selection method produced the highest seed yield and crosses of Hassawi2 by Luz and by TW had the highest seed yield/plant 15.4 and 13.3g, respectively.
On the other side M4 was the best selection method for non-stress conditions and TW x Hassawi2, TW x Hassawi3 and Luz x Hassawi3 recorded highest seed yield 41.7, 37.9 and 37.3g, respectively.
High values of PCV, GCV for M4 under non-drought suggested that bulk selection under favorite conditions increased the phenotypic and genotypic variance, particularly under same conditions.
heritability values were higher for each selection method under conditions that breed for it indicating that, selected high yields under specific condition may be combined with sensitive alleles to other condition.
Plants exposed to different conditions of drought and non-stress during the previous generations (M2 and M3) were had less response to environments changes with low seed yield.
