Abstract

A total of 19 selections derived from 4 sources of peppers with resistance to gray leaf spot (KC43, KC47, KC220, and KC319) were tested for their nuclear genotype of the gene conferring the ability to restore the cytoplasmic male sterility. All the selections derived from KC220 and KC319 were maintainers with a genotype of Nrfrf, while all the selections from KC43 and KC47 were restorers with a genotype of N(S)RfRf.

Key Words: Capsicum annuum, cytoplasmic male sterility, Stemphylium Lycopersici, S. solani
