Cytoplasmic male sterility of chilli cultivars was evaluated for their prospective genotypes. Fifteen pairs of F1 hybrids were evaluated for their male pollen viabilities in three natures. Hybrids which showed no pollen occurred in 9 varieties whose male parents should have the prospective genotypes of N rfrf or B line. Hybrids with fertile pollens in some plants and sterile ones on others appeared in 4 varieties whose male parents should have prospective genotypes of N/S Rfrf. Hybrids showing fertile pollens were found in 2 varieties whose male parents should have the male sterility controlling genes in the nucleus as N/S RfRf or C line. Horticultural characteristics of six accessions of chilies were recorded. Chilli fruits of the accessions were analyzed for the physico-chemical properties in terms of moisture content, total soluble solids, vitamin C, capsaicin content and skin color. Accessions CA1445, CA1449 and CA1450 were found to have suitable characteristics as maintainer lines.
