Resumo: | This study aimed to determine the chromosome number and the karyotype of Capsicum annuum, Capsicum chinense, Capsicum frutencens and Capsicum baccatum accessions in the active Capsicum sp. genebank at the Federal University of Piauí (BGC-UFPI). These species have great economic importance throughout the world, and their cytogenetic characterization can inform taxonomy and lead to improvement in the genus. Karyotypes were obtained from the rootlet meristems of the studied accessions using the squash method and Giemsa staining. The chromosome number 2n=2x=24 was verified for each of the four species. Chromosomal polymorphisms were observed for the C. frutencens accession BGC 37, which presented 12 pairs of metacentric chromosomes instead of 11 pairs of metacentric chromosomes and 1 submetacentric chromosome pair present in other accessions. In the accessions BGC 01 and BGC 37, secondary constrictions were observed in the 1 and 12 as well as in the 6 and 11 homologs, respectively. The karyotypes of the studied species were asymmetrical among themselves. The results obtained in this study confirm the high genetic diversity previously described in the literature for this genus. |
