Various Kharif onion genotypes including one check Agrifound Dark Red were evaluated to study the path coefficient analysis for twelve different characters. In the present investigation, average weight of marketable bulb/plant has been considered as dependable variable with the other traits. Here both genotypic path as well as phenotypic paths have been discussed. The analysis had revealed that fresh weight of bulb (0.756) is the most important contributing trait followed by polar diameter(0.156), marketable yield(0.084), plant height 120 DAT (0.0753) leaves per plant 90 DAT(0.070), TSS(0.038) and days to harvest(0.028). These all characters had highest positive direct effect on average weight of marketable bulb. Hence, more emphasis should be given to these traits while selecting the genotypes for increasing the average weight of marketable bulbs of these onion genotypes.
