Pedigree selection in one population of faba bean (Viciafaba L.) [electronic resource].

Includes references.

Two cycles of pedigree selection for one faba bean cross population i.e. Giza 429 x Giza 3 were done from F4 to F6 generations during three successive seasons, 2011/2012, 2012/2013 and 2013/2014. The obtained results showed significant differences among families at both cycles of selection. The overall families means exceeded significantly the best parent for seed yield/plant in the first cycle as well as, number of branches/plant, number of pods/plant and 100-seed yield/plant in the second cycle. The C1 families possessed considerable amount of genotypic and phenotypic variability for all studied traits. Consequently, high estimates of heritability were obtained. The variability between C2 families decreased rapidly for all studied traits. Positive significant genotypic and phenotypic correlations were detected between most pairs of traits at both cycles of selection. However, strong positive significant genotypic and phenotypic correlations were found between seed yield/plant and number of pods/plant at both cycles of selection, indicated number of pods/plant is a good selection criterion to improve seed yield/plant. The actual response to selection was higher than the expected response for all studied traits at the two cycles of selection .
