Abstract:

The present investigation was carried out in order to study the sterility maintenance and fertility restoration behavior of 47 new inbred lines on three CMS lines and also to estimate the combining ability and heterosis by crossing them in a L × T mating design. The resultant 141 hybrids along with their parents and two checks viz., KBSH-44 and KBSH-53 were evaluated in simple lattice design. Out of 47 inbred lines studied, 10 inbred lines viz., DOR-P-40 (oleic), GMU-456, GMU-716, GMU-746, GMU-759, GMU-773, GMU-785, GMU-1092, GP6-952 and GP6- 990 were identified as common fertility restorers for all the three CMS lines. Common fertility restorers for all the three CMS lines revealed that, even though the CMS lines differed in nuclear background, the fertility restoration genes could be same. It was evident from the present investigation that few inbred lines behaved differentially in the three CMS lines with respect to sterility maintenance and fertility restoration behavior, suggesting the presence of modifying genes, which could influence the fertility restoration thus, resulting in partial fertility. The identified 10 fertility restorer lines with high gca effect could be directly used as male parent in heterosis breeding programme for the development of superior hybrids.
