Ensuring the Success of Pigeonpea Hybrids by Focusing on Purity of Parental Lines and Appropriate Management Practices uri icon


  • Pigeonpea (Cajanus cajan (L.) Millsp.) is an important legume crop, grownmainly in the semi-arid tropics of Asia, Africa, Latin America, and the Caribbean.The total world area planted with pigeonpea is 4.6 million ha. India is thenumber one producer (3.5 million ha) of pigeonpea; despite this, there is notsufficient amount available to meet the nutritional needs of the large andmainly vegetarian resource-poor population and importation of pigeonpeafrom other countries like Myanmar and parts of Africa is needed to fulfill thecountry needs. Although dozens of pigeonpea varieties have been released,the productivity of pigeonpea has remained stagnant at around 700 kg ha-1. This is mainly due to various genetic, management, abiotic, and abioticconstraints. Since the area of pigeonpea cultivation is not likely to be increased,the emphasis moves to break the yield gap and to increase productivity bygenetic enhancement of germplasm by incorporating tolerance to bioticand abiotic stresses, and by replacing the traditional varieties with the newlydeveloped options
