The RSAP Analysis on Processing Pepper Resources in Guizhou Province
Twenty varieties of processing pepper in Guizhou province were identified by RSAP markers, which provided evidence for breeding of processing pepper and increased stability of product quality in production enterprises. Three pairs of RSAP primers were screened and they produced 72 amplifed fragments,47 of which (65. 3%) were polymorphic,with an average of 24 polymorphic fragments for each primer-pair and size ranging from 100 bp to 2 000 bp. The value of genetic similarity among 20 pepper accessions based on UPGMA varied from 0. 625 to 0. 931. The characters with different fruit shapes randomly distributed in the dendrogram,indicating that the genetic diversity of processing pepper cultivars from Guizhou province were abundant.
