The manifestation of heterosis for bulb yield and its component traits were studied in onion at ICAR-Indian Agricultural Research Institute, New Delhi. The main characters studied includes bulb yield, average bulb weight, bulb equatorial and polar diameter, neck thickness of plant and bulb, plant height, number of leaves and moisture content. It was studied in twelve CMS based short day onion hybrids and compared with commercial hybrid ‘Flare’. All the hybrids were differed significantly for all the traits studied. The most promising hybrid PR-121×EG exhibited 81.60% heterobeltiosis and 79.70% standard heterosis. The other promising hybrids for yield were PR-121×I-33, and PR-121× Sel.131. PR-121×EG, PR-121×Sel.397 and PR-121×PRO-6 were superior for polar and equatorial diameter of bulb, weight of ten bulbs, neck thickness of bulb and plant. Hybrids PR-121×Sel.102-1, PR-121×I 33, PR-121×Sel.383 were found best for moisture content.

Keywords: Short day CMS onion hybrids, heterosis, yield, bulb dimension and moisture content
