In the present investigation, the parents (P1 and P2), F1,’s, F2’s and BC1F1’s progenies of four selected hybrids involving four cytoplasmic genetic male sterile lines based on Cajanus scarabaeoides (A2) cytoplasm and four restorers from diverse source were evaluated to determine the inheritance of fertility restoration in pigeonpea [Cajanus cajan (L.) Millsp)] hybrids. Among these restorers, three restorers viz. BDNHR 1, BDNHR 21-2 and BDNHR 22-1-2 were identified and developed from segregating materials of interspecific cross involving C. scarabaeoides, however one restorer viz. BDNHR 60-2 from interspecific cross involving C. albicans wild species. The results revealed that the hybrids viz. BDN 2004-1A x BDNHR 1, BDN 2004-4Ax BDNHR22-1-2 and BSMR 736A x BDNHR 21-2 showed the monogenic dominant gene action (3:1) with single fertility restoring gene. However, only one hybrid viz. BDN 2004-2A x BDNHR 60-2 showed digenic duplicate gene action with complete dominance for fertility restoration in Pigeonpea hybrids. The information generated on genetics of fertility restoration will help in knowing the selection of breeding methods and further transfer of fertility restorer genes in to elite backgrounds.
