Pigeonpea is an important legume crop of rainfed agriculture system. Despite of concerted research efforts in pigeonpea improvement, stagnated productivity of pigeonpea during last several decades may be accounted to prevalence of various yield constraints and the situation is exacerbated by inadequate availability of genomic resources to undertake any molecular breeding programme. The yield levels remained unchanged despite of high yielding pure varieties released. In this scenario, like many cereal crops the use of hybrid technology in enhancing productivity has a potential. A stable...
