Abstract/Contents: | "Bermudagrass [cynodon dactylon (L.) Pers.] is widely distributed in China, but little information exists on genetic diversity within the germplasm pool. This study was conducted to assess variations in ploidy and amplified fragment length polymorphisms (AFLPs) among cynodon accessions collected from 11 Chinese provinces. Flow cyrometry and AFLP analyses were performed on 132 and 119 chinese accessions, respectively. Four ploidy cytotypes were found among the Chinese accessions. Tetraploid (2n=4x=36), accessions were most prevalent (88%), with nuclear genome sizes ranging from 1.96 to 2.30 pg/2C nucleus-1. the accession were grouped into five cluster based on 466 polymorphic AFLP bands. Genetic similarity coefficients (GSCs) of two clusters containing 'Tifway' and Tifgreen' ranged from 0.97 to 0.99, suggesting the triploid plants most probably were introduced cultivars from the USA. Within the Chinese indigenous accession, GSC ranged from 0.65 to 0.009. Tetraploid genotype had the greatest genetic variation with GSC ranging from 0.69 to 0.99, while pentaploids had the least with GSC ranging from 0.95 to 0.98. Genetic differentiation among the later three ploidy levels is evident. Fully sampling the genetic diversity of cynodon in china will require more comprehensive collection throughout its distribution." |
