Abstract:
Reproductive isolation, including hybrid weakness, plays an important role in the formation of species. Hybrid weakness in Capsicum , the cessation of plant growth, is caused by two complementary dominant genes, A from C . chinense or C . frutescens and B from C . annuum . In the present study, we surveyed whether 94 C . annuum accessions had B or b alleles by crossing with C . chinense having the A allele. Of the 94 C . annuum accessions, five had the B allele, three of which were native to Latin America and two were native to Asia. When combined with previous studies, the percentage of B carriers was 41% in Japan, 13% in Asia excluding Japan, 6% in Latin America, and 0% in Europe and Africa. In addition, 48 accessions of C . annuum from various countries were subjected to SSR analysis. Clades with high percentages of B -carriers were formed in the phylogenetic trees. In the principal coordinate analysis, most B -carriers were localized in a single group, although the group also included b -carriers. Based on these results, we presumed that the B allele was acquired in some C . annuum lines in Latin America, and B -carriers were introduced to the world during the Age of Discovery, as along with the b -carriers.
