Abstract

                                A study on the association of metric traits involving ten aggregatum onion lines (Allium cepa L. Var. aggregatum Don), with three testers and their 30 crosses revealed that the yield components like number of bulbs, weight of plants, T. S. S, shape index of bulb and bulb density exhibited significant positive association with yield. These components were also highly and positively inter-correlated among themselves. The path-coefficient analysis indicated that plant height, number of bulbs. weight of plant and days to maturity hed direct positive effects on yield; while number of leaves, T. S. S. shape Index and bulb density had negative direct effects. Weight of plant and number of bulbs are dependable indices of selection in identifying the yield potential of individual lines.
