Genetic Diversity Analysis and Construction of DNA Fingerprint Profiles of White Radish Based on SNP Molecular Markers
摘要
Abstract
Taking 31 white radish samples as test materials,the core SNP markers were developed by using Hyper-sequencing method.The relationship between the core SNP markers and the genetic diversity of radish varieties as well as the DNA fingerprinting was studied,in order to provide references for the analysis of genetic diversity of radish,identification of germplasm resources and breeding of new varieties.The results showed that,378 core SNP markers capable of efficiently identifying white radish varieties were obtained.The average values of its polymorphic information content and heterozygality were 0.473 and 0.411 respectively.It indicated that 378 markers could represent the genetic variation information of the test materials and effectively distinguish all the test materials.A comprehensive analysis was conducted on multiple aspects such as principal components,genetic relationships,genotypes,and phylogenetic evolutionary trees,and 31 white radish materials were classified into 5 groups.DNA fingerprinting QR code was constructed for each serving of white radish material based on 378 core SNP markers.关键词
