SUMMARY

The present investigation was conducted to evaluate the level of genetic variation in the faba bean population for yield and its component traits at Research Farm Area, MAP section,
Department of Genetics and Plant Breeding, CCSHAU, Hisar in the Rabi season of 2019-20. Sixty faba bean genotypes along with two checks i.e., HFB-1 and Vikrant were evaluated in augmented randomized block design. Analysis of variance showed highly significant differences among checks, between check & genotypes and among genotypes for all the studied traits. High genotypic and phenotypic coefficient of variation was observed for hundred seed weight (21.93%, 23.02%), seed yield per plant (47.53%, 48.25%), biological yield per plant (50.11%, 52.01%) and harvest index (31.92%, 32.25%) suggesting the presence of considerable variation in the faba bean genotypes. High or medium heritability coupled with high genetic advance as percent of mean was observed for the number of pods per plant (32.42%, 20.91%), hundred seed weight (79.93%, 28.46%), seed yield per plant (49.17%, 33.45%) and harvest index (38.51%, 22.45%), indicating these traits could be easily improved through direct selection. The genotypes like EC-10908, EC-361494, HB-89, NDFB-13 was found to performing better in this investigation.
