Fertility restoration system in five CMS-based pigeonpea [(Cajanus cajan (L.) Millspaugh] hybrids was studied during kharif 2010 at International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Patancheru, Andhra Pradesh. Two hybrids ‘ICPH 2671’ and ‘ICPH 2740’ which had the same male parent but different females segregated in F2 in the ratio of 12 fertile (F) : 3 partial fertile (PF) :1 sterile (S), and in BC1F1 generation as 2 fertile : 1 partial fertile : 1 sterile, suggesting that fertility restoration in these hybrids was controlled by digenic dominant epistatic interaction. The progenies derived from hybrid ‘ICPH 3359’ fitted well to an F2 ratio of 9 F : 6 PF : 1 S, and 1 F : 2 PF : 1 S in BC1F1 generation, indicating the involvement of two major genes with incomplete dominant epistasis. Progenies of the other two hybrids ‘ICPH 4012’ and ‘ICPH 4344’ segregated in F2 in the ratio of 9 F : 3 PF : 4 S, and 1 F : 1 PF : 2 S in BC1F1 generations, suggesting that pollen fertility was controlled by digenic recessive epistatic gene action. Results of the present investigation revealed that fertility restoration of A4 CMS system in pigeonpea was governed by two major genes but with different types of epistatic interactions in different crosses.
