A study conducted to estimate the magnitudes of heterosis for fruit yield and its components in brinjal. Thirty two F1 hybrids (generated by line x tester mating design using diverse eight lines and four testers) along with 12 parents and one check were evaluated in a randomized block design with three replications at Vegetable Research station, Junagadh Agricultural University, Junagadh, Gujarat (India). Appreciable heterosis was found over better and standard parents for all the traits studied in desirable direction. In order of merit, the highest heterobeltiosis was recorded by cross NSR 1 x Swarna Mani Black (46.00%) followed by NBR-14-01 x Swarna Mani Black (40.03% and NSR-1 x Pant Rituraj (39.35%), while cross NSR 1 x Swarna Mani Black ranked first by recording the highest standard heterosis (62..00%) for fruit yield per plant followed by NBR-14-01 x Swarna Mani Black (55.39%) and AB-15-07 x Swarna Mani Black (50.09%). The above crosses also exhibited desirable heterosis for important yield attributing characters like fruit length, fruit girth, fruit weight and number of fruits per plant. The present study revealed good scope for isolation of pure lines from the progenies of heterotic F1s as commercial exploitation of heterosis breeding in brinjal.
