Abstract:

In order to explore the molecular markers associated with significant phenotypic traits of radish, we identified 14 phenotypic data of 60 radish samples, and screened out 29 molecular markers with polymorphism (12 SNP markers and 17 InDel markers) for genetic diversity analysis. The general linear mode (GLM) of TASSEL5.0 software was used for correlation analysis of 14 phenotypic data of radish. The results showed that the number of alleles (Na) of 29 molecular markers ranged from 2 to 3, with an average of 2.14. The frequency of major alleles (MAF) ranged from 0.53 to 0.94, with an average of 0.68. The expected heterozygosity (He) for each marker ranged from 0.12 to 0.93, with an average of 0.63. The polymorphism information content (PIC) values of each locus ranged from 0.11 to 0.37, with an average value of 0.32. Among the 12 phenotypic traits, 17 significantly correlated molecular marker sites (7 SNP markers and 10 InDel markers) were associated (P≤0.01), and the contribution rate was 7.24%-23.25%.
