The study involved tfic evaluation of 45 hybrdis along with 18 parents to assess combining abilitv of parents, estimation of heterosis over better parent and to identify the potential hybrid combination for 17 growth, yield, quality and resistance traits. The combining ability studies indicated that the parents kaddi, VN- 2, Jwala, LCA-312, KDC-1 and Arkalohit could be utilised in breedmg programme since they expressed highly significant positive GCA effects for dry fruit yield per plant. The parents VN-2, LCA-301, PMR-5 and CA-219 for thrips and VN-2, Hissar shakthi and Arkalohit for mites were found good general combiner. Evaluation of Fis indicated that the crosses VN-2 X BC-24, Kaddi x KDC-1 and Kaddi x PMR-5, VN-2 x Arkalohit, VN-2 x Jwala and Kaddi x Arkalohit are found promising could be exploited. The hybrid combination Kaddi x Phule-5, Kaddi x Hissar Shakthi, VN-2 x LCA-312, Dabbi x LCA-312, Dabbi x Arkaabir and Kaddi x BC-14-2 were identified as potential material for further breeding programme, promising recombinants are derived from the cross Kaddi x LCA-312 and Dabbi x LCA-312 could be advanced to derive pure lines. To undcr-stand the nature and magnitude of gene effects nine crosses were analysed through generation mean analysis for 15 character. The study indicated that the growth related traits were found to be under the control dominance and additive x additive type of gene interaction. Fruit related traits were under the control of additive, additive x additive type of gene interaction. Resistance to thrips and mites was under the control of non-additive gene effects i.e. dominance, additive x additive and additive x dominance, it suggest that inclusion of parents having high level of resistance for the development of hybrids or to derive pure lines. Dry fruit yield was under the control of dominant and additive X additive type of gene interaction. In order to exploit non-additive gene action development of hybrid is suggested. For the development variety recurrent pedigree selection programme is suggested involving the parents having high level of resistance with high fruit quality traits."ennullThesis
