Abstract: The present investigation was carried out to character association and path coefficient analysis among thirty genotypes of onion for fourteen characters comprised of bulb yield and its contributing characters. These genotypes were planted in Randomized Block Design with three replications during Rabi-2016-17, SKN College of Agriculture, Jobner. The result from character association indicated that bulb yield showed significant and positive correlation with number of scales, equatorial diameter, bulb volume, polar diameter, plant height, neck thickness, days to harvest after transplanting, number of leaves, pungency, sulphur content in bulb, dry matter content and TSS. Path coefficient analysis revealed that characters viz. equatorial diameter, plant height at harvest, pungency, neck thickness, dry matter content had positive direct effect on bulb yield. Hence, these characters may be simultaneously selected for developing better quality high yielding varieties of onion.
