Hybrid technology in enhancing productivity of grainlegumes uri icon

abstract

  • Grain legumes are considered as the best option for diversification and intensification of agriculturebecause of their intrinsic values such as nitrogen fixing ability, higher protein content, and ability to thrivewell in poorly endowed environments. These are invariably grown under unfavorable marginal lands with lowaverage productivity over the last few decades. Among these grain legumes, pigeonpea (Cajanus cajan (L.)Millspaugh) offers an opportunity for breaking the yield barrier through hybrids. In the last few years fivedifferent CMS sources have been bred. Among these A2 (C. scarabaoides) and A4 (C. cajanifolius) are beingused in hybrid breeding programmes. Two commercial hybrids GTH 1 and ICPH 2671 have recorded 25 -40% yield advantage over standard varieties in farmers? fields
