Eighteen divergent lines of chilli and 45 F1 hybrids were studied to investigate the general and specific combining ability effects for LCI for thrips and mites. The degree of dominance indicated that the LCI for thrips was predominantly under the control of additive gene effect, whereas the LCI for  mites exhibited the non-additive gene effect Among the parents VN-2, PMR-5, CA-219, Phule-5, AKC-86-39, LCA-301, CO-2 for thrips and  for mites the genotypes Arka Lohit, LCA-312 are found to be the good general combiners Among the hybrids Six  crosses have exhibited significant negative sca effect for thrips are  VN-2 x Arka Abir ( H x L), VN-2 x LCA-312 ( H x H), B-Dabbi x CA-219 ( L x H), B-Dabbi x PMR-5 ( L x H), B-Dabbi x CO-2 (L x H)and for mites B-Kaddi x LCA-301, B-Kaddi x KDC-1, B-Dabbi x CO-2, B-Dabbi x PMR-5. Breeding methods for incorporation of resistance to thrips and mites are recurrent selection like diallel selective  mating or biparental  mating in early segregative generation by involving resistant and high gca parents are suggested.
