| Abstract | Genetics of fertility restoration in four restorer lines viz., IR-69702-52-3-3R, IR-62161189-3-1-3-2R, KBNT-11 and IR-59669-93-1-3R was studied in “Wild Abortive” cytoplasmic male sterility system using cytoplasmic male sterile line, APMS6A. It was found that fertility restoration evaluation of the plants in F2 of all the four crosses viz., APMS 6A x IR-69702-52-33R, APMS 6A x IR-62161-189-3-1-3-2R, APMS 6A x KBNT-11 and APMS 6A x IR-59669-931-3R showed a segregating ratio of 15 fertile: 1 sterile indicated digenic inheritance with dominant duplicate gene action. It can be concluded that the presence of dominant duplicate genes in four restorer lines viz., IR-69702-52-3-3R, IR-62161-189-3-1-3-2R, KBNT-11 and IR59669-93-1-3R governing fertility restoration in the WA-CMS system. |
