The fertility of cytoplasmic male sterility(CMS) can be restored by nuclear-encoded fertility restorer genes. However, the number and modifications of these restorer nuclear genes remain poorly understood. In this study, using QTL Ici Mapping software an intraspecific genetic linkage map of Capsicum annuum was constructed, and 2 major and 7 minor quantitative trait loci(QTLs) were identified, which acting as restorer-of-fertility(Rf) genes counteracting CMS. The heritability of the 2 major loci reached 92.5...
Cytoplasmic male sterility(CMS),a trait charac-terized by the failure to produce functional pollen,has been frequently associated with chimeric openreading frames(ORFs)resulting from rearrange-ments in the mitochondrial genome.CMS is one ofthe most import
