Abstract

The productivity potential of cowpea in Tamil Nadu is low 265 kg/ha as compared to the national productivity. This clearly indicates the necessity to identify the reason for such a low productivity in India and particularly in Tamil Nadu. The limited number of cowpea breeding programs in Tamil Nadu has contributed to the ineffective production. To overcome this issue, the main focus of the present investigation is to identify the promising segregants for further use in future breeding programmes. An investigation was carried out in F2 and F3 generations of four inter subspecies crosses of cowpea. The F2 and F3 progenies were evaluated along with their parents. The breeding nature of the segregants were investigated by parent progeny regression for the traits viz., days to first flowering, plant height, number of clusters per plant, number of pods per plant, pod length, number of seeds per pod, hundred seed weight and single plant yield. Selected single plants based on days to first fl

Conclusion

It may be concluded that, number of clusters per plant, number of pods per plant, number of seeds per pod and hundred seed weight were the yield contributing traits and by performance, the crosses RC101 × Vyjayanthi and ACM 05 07 × Vyjayanthi were superior and desirable characters like dwarf, early duration and long purple pod inherited to their progenies in later generation.
