Nature of genetics of targeted and basic traits is very crucial for selection of appropriate parents and breeding strategies for BPH tolerance and yield enhancement in rice. In this study, six generations (P1, P2, F1, F2, B1 and B2) of CRMS32B/CR 2711-76 and IR42266-29-3R/CR 2711-76 analysed at ICAR-NRRI, Cuttack, Odisha. Gene actions analysis for yield and contributing traits along with BPH resistance was studied. Results revealed that panicle initiation, grain yield per plant, test weight, pollen load (IR42266-29-3R based generations) pest severity, ASV, AC and HRR exhibited duplicate epistasis gene action whereas other traits indicated complimentary gene actions.
