Pigeonpea is an important food legume crop of semi-arid tropical regions. Plateauing of pigeonpea yield has been worrying breeders for the past 6–7 decades. Serious breeding efforts made during this period resulted in various high-yielding and disease resistant cultivars. However, the gains in pigeonpea productivity have been modest. The authors, while reviewing this situation, conclude that long generation turnover, complexity of biological traits, low selection response and overreliance upon pedigree breeding present the key bottlenecks for this situation. In this paper, some alternative breeding approaches and technologies are suggested for the genetic enhancement of yield stability and stress response of pigeonpea.

提高木豆（Cajanus cajan）产量增加​​和应激反应的替代育种方法

鸽豆是半干旱热带地区重要的食用豆科作物。在过去的 6-7 年里，木豆产量的稳定一直让育种者感到担忧。在此期间进行的认真育种努力导致了各种高产和抗病品种。然而，木豆生产力的提高是有限的。作者在回顾这种情况时得出结论，世代周转时间长、生物性状复杂、选择反应低和过度依赖谱系育种是这种情况的关键瓶颈。本文提出了一些替代育种方法和技术，用于提高木豆产量稳定性和逆境响应的遗传增强。
