The analysis of variance revealed significant differences among all the 51 genotypes for all the fourteen quantitative characters studied indicating a high degree of variability in the materials during both the respective years. The magnitude of heterosis varied from cross to cross for all the characters studied. For fruit yield per plant, among 36 cross combinations, maximum relative heterosis was observed in EC169506 × Arka Anamika (43.13% and 37.13%) followed by EC169400 × Arka Anamika (25.55% and 30.10%), IC117351 × Arka Anamika (25.00% and 30.20%) and EC169430 × Parbhani Kranti (244.39% and 29.48%) during both the respective years consistently. Whereas, only two cross combinations viz., EC169400 × Arka Anamika (23.70% and 24.27%) and IC117351 × Arka Anamika (23.36% and 29.25%) exhibited consistent significant positive heterosis over better parent in desirable direction during both the respective years for fruit yield per plant. The high heterotic response in these hybrids for fruit yield per plant resulted mainly due to substantial heterosis for number of fruits per plant, fruit length, plant height, and inter-nodal length.
