A preliminary identification of Rf*-A619, a novel restorer gene for CMS-C in maize (Zea mays L.).

ABSTRACT: C-type cytoplasmic male sterility (CMS-C) is widely utilized for hybrid maize seed production. However, genetic mechanisms underlying the fertility restoration are very complicated. At present, there is a divergence on the number of fertility restorer genes in maize inbred line A619 for CMS-C. To further elucidate the restoring mechanism of A619, we used genetic analysis and molecular markers to confirm the restorer genes of maize inbred line A619 for C-type male sterile line C48-2 in this study. Firstly, the fertility segregations of (C48-2 × A619)F₂ populations were investigated under three environments during 2013-2015. The segregation ratio of fertile and sterile plants in the F₂ population fit to 15:1 via chi-square test and this result suggested that there are t
