Abstract
Heterosis is widely utilized for the selection of superior cross combinations. Since the heterosis has become commercially feasible in developing hybrid brinjal. In the present investigation, six parents were selected on the basis of divergence and crossed in diallele design. The manifestations of hybrid vigour in thirty hybrids were studied. Significant heterosis over better parents and standard check was observed for yield attributes and Fruit borer incidence. The hybrid KS-224 × Swarna Mani and SBRB-6/12 × SBRB-3/12 expressed significant and desirable heterobeltiosis and standard heterosis for yield and fruit borer incidence. Heterosis for fruit yield per plant ranged from -31.78% (SBRB-2/12 × KS224) to 60.40 percent (KS224 × Swarna Mani) over better parent and -5.01% (SBRB-2/12 × KS224) to 88.79% (SBRB-3/12 × SBRB-2/12) over standard parent.
