%X 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.
