Snap bean is becoming an important vegetable crop in Ethiopia primarily produced for export markets. Although several research results indicated strong association of green pod yield with yield contributing traits in snap bean, limited information is available under Ethiopian condition. Field experiment was conducted to study the nature and extent of association among 16 traits in snap bean genotypes. Positive and significant genotypic correlation was observed between green pod yield with number of pod per plant (rg=0.775), single green pod weight (rg = 0.664), pod dry weight (rg = 0.333), pod length (rg = 0.537) and leaf area per plant (rg = 0.665) while significant negative genotypic correlation was found between green pod yield and days to 50% flowering (rg = -0.437) and days to first picking (rg = -0.557). Genotypic path analysis showed that pod number per plant exerted the maximum positive direct effect (0.688) on green pod yield followed by single green pod weight (0.539) while plant height exhibited maximum negative direct effect (-0.458). Generally, traits having positive and significant correlation and high direct effect on green pod yield revealed direct selection of these traits could bring about green pod yield improvement in snap bean.
