Abstract

Fusarium wilt is one of the most destructive biotic stresses of pigeonpea [Cajanus cajan (L.) Millsp.] and the annual production losses approach over US $71 million. Availability of high yielding wilt resistant cultivars with wide adaptation is the ideal solution to overcome this production constraint on a sustainable basis. To achieve this, a clear understanding of the genetic control of disease resistance helps in formulating appropriate breeding strategies. Hence, the present study was undertaken to determine the mode of inheritance of FW using mapping populations, including two sets of Recombinant Inbred Lines (RILs). The phenol typing data revealed that the resistance to FW was controlled by mongenic dominant and recessive gene actions in the two RILs. Besides this, the breeding materials generated from this study can be used to derive high-yielding inbred cultivars and hybrid parents.
