Abstract

A single faba bean (Vicia faba L.) population derived from the cross                Sakha 3 x Giza 2 was subjected to two cycles of pedigree line selection (PSM). Selection criteria included seed yield/ plant (SY/P), number of pods/ plant (NP/P), and seed index (SI). Analysis of variance revealed significant differences among families within the F3 and F4 generations for all studied traits, indicating successful selection progress. Notably, mean values for all traits, except days to flowering, increased from cycle 1 to cycle 2. Days to flowering exhibited the opposite trend, with a higher mean value observed in cycle 1. The expected gain from selection (EGS%) for SY/P in the F2 generation was 29.52 and increased in the F3 and F4 generations in values of 34.41 and 2.06, respectively. The realized gain from selection (RGS%) for SY/P in the F3 generation was 23.06, then decreased in successive generation which amounted to 9.56 in F4. Multiple promising faba bean genotypes were identified within Families 1, 2, 13, 56, and 60. These families exhibited superior performance in relative yield traits compared to the better parent, check variety, and bulk samples. Additionally, they displayed favorable values for most characters assessed. These findings suggest their significant potential for incorporation into breeding programs to enhance faba bean yield.
