The present study was undertaken to identify potential parents and superior cross combinations for yield and yield attributes. Twenty two hybrids generated by crossing with single tester (Parbhani Kranti) and twenty three lines along with parents for studying of heterosis, plant height, number of primary branches/plant, fruit length, number of fruits per plant, fruits weight per plant, fruit yield (q/ha) during rainy season of 2008-09 and 2009-10 at Vegetable Research Centre, Govind Bhallabh Pant University of Agriculture and technology, Pantnagar, Uttrakhand, India. The magnitude of heterosis varied from cross to cross for all the characters. The highest plant height was found in parent (AC-177) and cross (KS-404XPK), number of primary branches in parent (Pant Sel-1) and cross (AC-176XPK), fruit length in parent (AC-123) and cross (AC-123XPK), number of pods per plant in parent (AC-123) and cross (AC-123XPK) and fruit weight per plant in parent (AC-45) and cross (AC-177XPK). Thirteen crosses showed significant heterosis for fruit yield (q/ha), in which maximum heterobeltiosis, relative heterosis and standard heterosis were found in AC174XPK (158.86), AC 177XPK (136.67) and KS 404XPK (165.03%). Ten crosses showed the highest significant heterosis, in which maximum heterobeltiosis, relative heterosis and standard heterosis were found in AC 123XPK (200.00%), (181.63%) and (200.26) followed by in AC 177XPK for number of fruits per plant.
