Abstract

The knowledge of the genetic diversity among the accessions in germplasm banks it is important for the conservation of genetic resources and the use in breeding programs. This study aimed to evaluate the genetic divergence of 23 accessions of the genus Capsicum, and was based in seven quantitative and nineteen qualitative multicategorical descriptors and using multivariate techniques. The analyses of variance revealed significant difference (P<0.05) among the accessions of peppers for all quantitative descriptors. The coefficient variation ranged from 8,97% (LF) to 30,91% (NFA). The Tocher optimization method detected eight clusters for quantitative descriptors and also in as well as qualitative multicategoric descriptors. The UPGMA method detected three clusters for quantitative descriptors and four clusters within qualitative multicategoricdescriptors. There is genetic diversity inter and intraspecific in germplasm bank of Capsicum coming from The Federal University of Piauí, and these results indicate that there are not duplicated accessions.
