Assessment of the Genetic Diversity of Pummelo Germplasms Using AFLP and SSR Markers
摘要
Abstract
The genetic diversities of 110 pummelo germplasms and 12 of their relatives were analyzed by SSR and AFLP methods. Approximately 99.1% of the 335 SSR loci were polymorphic, and 9.85 alleles per SSR locus were identified. The gene diversity values changed from 0.1939 to 0.9073, and 46 SSR polymorphic bands were scored. 72% of the 343 AFLP loci were polymorphic, and 82 polymorphic loci per AFLP were identified. Heterozygosity changed from 0.21863 to 0.28445,and 44 AFLP polymorphic bands were scored. The UPGMA result showed that 122 pummelo genotypes and their relatives could be divided into eight groups, and the pummelo genotypes composed mainly of Shatian pummelo varieties group,Wendan pummelo vareties group and a huge hybrid pummelo varieties group. The classification result was expected to widen the genetic background of pummelos using various target varieties.关键词
