Abstract
The present study was carried out during the five seasons 2008/09, 2009/10, 2010/11, 2011/12 and 2012/13 at Sakha Agricultural Research Station, Kafr El-Sheikh governorate, Egypt. The study aimed at evaluating the effectiveness of pedigree, bulk (natural selection), single pod descent (SPD) and mass selection breeding methods on improving faba bean seed yield and resistance to foliar diseases i.e,chocolate spot Botrytis fabae and rust Uromyces fabae .
Three F2 populations derived from three crosses were used. Ten pure lines derived from each of the four breeding methods in each cross were tested for days to maturity, seed yield (ardab/fed.), reaction to chocolate spot and rust disases in a randomized complete block design with three replications. Significant seed yield differences existed within F6 pure lines of each cross by applying each of the four methods.
Both cross-progenies and breeding methods squares were highly significant for all studied traits. The interaction of cross-progenies by breeding methods mean squares was highly significant for all studied traits and also the interaction of cross progenies by pure lines, breeding methods by pure lines and the second order interaction of cross-progenies by breeding method by pure lines were highly significant for seed yield (ardab/fed.) while the same interactions was not significant for the other traits i.e., days to maturity and reactions to chocolate spot and rust. The cross-progeny; Sakha 2 x TW was the earliest in maturity when bulk method was applied, while the cross-progeny; Sakha 1 x RM had the highest seed yield with the pedigree method and the cross-progeny; R.M. x Giza 3 was more resistant to both chocolate spot and rust under the breeding method of single pod descent.
Pedigree method recorded its superiority than the other breeding methods with respect to broad sense heritability and subsequently expected and predicted genetic advance in the cross-progenies; Sakha 1 x Rina Mora and Rina Mora x Giza 3 for seed yield/fed. While in the cross progeny; Sakha 2 x TW, the breeding method of single pod descent had the highest broad sense heritability, expected and predicted genetic gain upon selection of the highest 20% plants in the population for the same trait.
It could be concluded that the pedigree and SPD methods were more efficient and could be less expensive in breeding for improving seed yield and foliardiseases (chocolate spot and rust) resistance of faba bean.
