Abstract

Nine diverse parents were crossed in a diallel fashion (excluding reciprocals) for generating the experimental material. All the nine parents and their 36 hybrids were grown in a randomized block design with three replications. In the present study, the significant and highest general combining ability effects were recorded in fruit yield JRG-2 (0.2), highest average fruit weight was recorded in JRG-2 (20.54), for total soluble solids Pusa Nasdar (0.31) and dry matter Satputia (0.38). The maximum and significant sca effects showed in the crosses for their respective characters includes Pusa Nutan × Satputia (0.38) for total yield, Pusa Nasdar × Satputia (25.06) for fruit weight, Pusa Nasdar × Satputia (0.95) for total soluble solids and dry matter Pusa Nutan × JRG-2 (1.48).The highest significant heterosis over mid and better parent for fruit yield was noticed in DRG-5 × Satputia (151.85% and 139.89%). For fruit weight the highest heterosis over mid, better and standard parent was recorded in the crosses Pusa Nutan × Satputia (76.79)%, Pusa Nasdar × JRG-3 (12.06%) and JRG-2 × Swarna Manjari (27.22%), for total soluble solids maximum significant heterosis over mid, better and standard was recorded in Pusa Nasdar × Satputia, and significant dry matter content was obtained in the crosses Pusa Nasdar ×JRG-2 (41.04%) over mid, JRG-3 × Swarna Uphar (33.45%) over better and Pusa Nasdar × JRG-2 (28.78%) over standard parent.
