Abstract:

By using SLAF-seq technology, 17 main cultivated varieties and one wild variety of Trapa L. in Jiangsu and Zhejiang areas were high-throughput sequenced, 445 594 SLAF tags were obtained, and 95 931 polymorphic SLAF tags were identified. A total of 269 338 SNP markers obtained were used to construct the phylogenetic tree and analyze the population structure for the 18 samples of Trapa L. The results showed that SLAF-seq technology could efficiently develop a large number of SNP markers which could be used for population genetic analysis. Different types of Trapa L. were distinguished well by the SNP-based phylogenetic analysis. These results provided a reference for the further identification of germplasm resources and the research on the genetic evolution of Trapa L.
