Abstract:
Half dialed analysis was carried out during kharif- 2017 at Instructional-Cum-Research Farm, Department of Horticulture, College of Agriculture, Latur, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani to study the heterosis per cent for yield and yield contributed characters. The 21 F₁ hybrids along with their seven parent ware evaluated. Observation were recorded on five randomly selected yield attributing character viz., plant height, plant spread, number of primary branches, number of days required for first flowering, number of days required to 50% flowering, number of fruits per cluster, fruit diameter, fruit length, number of fruits per plant, fruit weight, yield per plant, yield per plot and yield per hectare tagged plant from each treatment for yield. The values of F₁ averaged over replications were used for estimating heterosis. Manifestation of heterosis of higher order for number of fruit plant^-1, length of fruit, weight of fruit, weight of fruit plant^-1 and fruit yield ha^-1. The maximum heterosis over better parent for fruit yield ha^-1 was observed to be 172.72%. Three potential heterosis cross combinations viz., Kateri Vange x Brinjal CVK, Malapur Local x Manjari Gota, Brinjal CVK x Manjari Gota and Brinjal -64 x Brinjal CVK were identified as for promising for fruit yield per hectare.
