Inheritance of seed yield and some yield components of faba bean using six populations

Abstract EN

Six populations P1, P2, F1, F2, BC1, and BC2 of two faba bean crosses were established during winter 2013/2014 to 2014/2015 seasons and evaluated in 2015/2016 winter season at Experimental Farm, Faculty of Agriculture, Al-Azhar University at Assiut Branch.

The mean values of F1 surpassed the high parent in each cross for all the studied traits, indicating over dominance.

Variance estimates of the segregating generations were greater than that of the F1 and their parents.

The magnitude of dominance was higher than additive effects for all studied traits in the two crosses, indicate the importance of dominance gene effects in the inheritance of all studied traits.

High genetic gain was found to be associated with rather high and moderate heritability estimate for most studied traits, therefore selection for these traits in the two crosses under investigation should be effective and satisfactory.
