Abstract/Contents: | "The genetic diversity of 31 Poa L. accessions ( 6 species) was analyzed using ISSR markers, in order to understand genetic differences among Poa L. germplasm and provide reference for germplasm resource protection, breeding and molecular identification. Results indicated that there was abundant genetic diversity in Poa germplasm. Total 111 bands were detected by 6 primers, and the percentage of polymorphic bands (PPB) was 97. 79%. Nei's gene diversity index (H) was 0. 4239; the Shannon diversity index (I) was 0. 6137. The genetic similarity (GS) among 31 accessions was 0. 4146~ 0. 9512. The 31 accessions were classified into 6 major groups based on UPGM A cluster analysis. Poa alpigena L. had the highest genetic differentiation and clustered a unique group. Seven American accessions of Poa pratensis L. were classified into one group. The accessions from same origin were classified into the same group indicating the geographical distribution of genetic diversity. The genetic relationships and diversities among Poa germplasm were also discussed for future research and application of Poa germplasm at the molecular level." |
