Evaluation of BC₁F₂ and F₃ Populations derived through wide hybridization for yield and component traits in pigeonpea

Introgression for yield and its component traits in pigeonpea was studied in the BC₁ F₂ and F₃ populations derived rom an interspecific cross between Cajanus scarabaeoides (ICP 15683) and C. cajan (ICPL 20329). In both the populations, a wide range of variation was observed for different traits, viz. fruiting branches per plant, pods per plant and yield per plant. The BC₁F₂ derivatives recorded mean superiority of 100%, 94% and 45.9%, while F₃ derivatives recorded superiority of 57%, 31% and 15% over the recurrent parent ICPL 20329 for fruiting branches per plant, pods per plant and seed yield per plant, respectively. Seed yield per plant had highly significant and positive association with pods per plant and fruiting branches per plant.
