Abstract
An experiment was conducted to study the variability, correlations and path coefficients for 9 metric traits in 100 faba bean (Vicia faba L. ) genotypes during winter (rabi) season of 1993 and 1994. Significant genotypic differences were observed for all the traits in bath the yea rs. The genetic variability as estimated by its component parameters l ike variances and coefficients of variation was high for plant height, pod-bearing length, harvest index, fruiting branches/plant, pods/plan t and seed yield/plant. High heritability was followed by high genetic advance for the latter 3 characters indicating the scope for their im provement through selection. Seed yield/plant was positively correlate d with plant height, pod bearing length, pods/plant and harvest index and negatively correlated with days to maturity both at genotypic and phenotypic levels, The harvest index had the highest direct effect on seed yield which was followed by pods/plant and 100 seed weight. Plant height and pod bearing length had the highest indirect effect. Plant height, pod bearing length, pods/plant and harvest index were the prin cipal yield attributes.
