Field experiment were conducted during three successive winter seasons 2013/14, 2014/15 and 2015/16 at Merowe in the Northern state of Sudan, to study genetic variability, heritability, genetic advance, genetic advance as percent of mean and correlation coefficient for seven quantitative traits of faba bean. The field was laid down in a randomized complete block design with three replications. Analysis of variance revealed highly significant differences (P ≤ 0.001) among the genotypes for all the morphological traits measured. All the tested genotypes gave significantly heavier seed weight than the check. High phenotypic coefficient of variation (PCV) coupled with high genotypic coefficients of variation (GCV) were observed for 100 – seed weight, plant height, days to 50% flowering and number of pods per plant, which indicates the presence of high genetic variation. The broad sense heritability estimates were high for all the characters. High heritability coupled with high genetic advance as percent of mean was observed for 100 – seed weight and number of seeds per pod and days to 50% flowering, indicating operation of additive gene action and the ample scope for improvement in these traits through simple selection. Significant positive correlations were detected between seed yield and each of number of pods per plant and plant height. These findings indicated that selection for number of pods per plant and plant height would be accompanied by high yielding ability under such conditions.
