Performance of several newly bred faba bean lines [electronic resource].

Two field trials were conducted during 2001/2002 and 2002/2003 growing seasons at Deirab Agricultural and Experimental Research Station, College of Food and Agriculture Sciences, Riyadh, King Saud University, Saudi Arabia to evaluate eighteen promising breeding lines compared with Giza 3 cultivar. Data revealed highly significant differences among tested genotypes for all traits, which indicated wide genetic variability. Mean squares of genotypes x season interaction were significant for studied traits except 100-seed weight and seed yield (t/ha). Data revealed that line 1 followed by lines 4, 5 and 6 showed the highest mean values for seed yield and recorded 3. 7, 3.55. 3.46 and 3.29 (t/ha), in the same order. The phenotypic and genotypic variances and coefficients of variability and heritability and genetic advance from selection were estimated for yield and associated traits. Results indicated that seed yield (t/ha) was significantly positively correlated with each of plant height. 100-seed weight. seed weight/plant and biological yield (t/ha), but negatively correlated with maturity date. Moreover, the relationship between seed yield (t/ha) and its components would be considerable value to breeders for screening breeding materials and selecting donor parents for breeding programs.
