The present study was conducted during 2011/12, 2012/13 and 2013/14 seasons at Sakha Agricultural Research Station, ARC, Kafr El-Sheikh Governorate, Egypt . Quantitative analyses were done by crossing between four faba bean (Vicia faba L.)  parental genotypes namely Giza 40, Giza 429, Sakha 1 and Triple white (TW) to produce three crosses namely; Giza 40 x Giza 429 (I), Sakha 1 x Giza 429 (II) and Giza 429 x TW (III). The parental genotypes could be arranged into two groups. The first group included Sakha 1 where it is considered as the most resistant group to foliage diseases i.e,chocolate spot Botrytis fabae (Sard) and rust (Uromyces viciae-fabae, Pers.) Schrot., and high yielding ability. The second group included Giza 40, Giza 429 and TW as susceptible genotypes with low yielding potentiality. Generation mean analysis was used to estimate genetic variance components in the crosses for nine traits. Heterosis over mid and better parent for all traits were highly significant except plant height in the first (Giza 40 x Giza 429) and second (Sakha 1 x Giza 429 crosses relative to mid parent, in the first cross (Giza 40 x Giza 429) relative to better parent, also the first cross had non-significant for no. of branches/plant and reaction to rust relative to mid parent and for no. of pods/plant relative to better parent. Also, the second (Sakha 1 x Giza 429) and third crosses (Giza 429 x TW) showed non-significance for chocolate spot relative to mid-parent and for 100 seed weight relative to better parent. The inbreeding depressing estimate was positive significant and/or highly significant for no. of branches/plant and no. of pods/plant, while it was negative significant for no. of seeds/pod in the three crosses. Heritability values in broad sense were generally higher than the corresponding values in narrow sense in all crosses for all traits. The additive genes seems to apply an improvement role of the inheritance of most of traits especially no. of pods/plant and no. of seeds/pod in the second cross; (Sakha 1 x Giza 429), where the differences between broad and narrow sense heritability were closes. The indirect selection in the progeny of this cross (Sakha 1 x Giza 429) and direct selection in the progeny of other crosses would be fruitful due to the high values of narrow sense heritability and the prediction genetic advance in these crosses. The additive type (a) was significant positive and negative in all of crosses for most traits except no. of branches/plant and no. of seeds/pod in the first (Giza 40 x Giza 429) and third (Giza 429 x TW) crosses. For dominance effect (d) it was higher in magnitude than that of additive type of gene effects. The additive x additive (aa) gene effect was highly significant in most crosses for all traits, except in a few cases. However, highly significant positive and negative epistatic gene action (ad) was observed in most crosses for most traits. The same trend was found with respect to dominance x dominance (dd) where positive and negative significant were observed for most crosses for most traits.
