Development and Verification of SCAR Marker Linked to Maturity in Tetraploid Potato
摘要
Abstract
Maturity is one of the most important quantitative traits in potato. In this study, a maturity linked molecular marker SCAR5-8 was developed using Zhongshu 3, Zhongshu 19 and their F1 segregation population consisting of 221 individuals via reduced-representation sequencing and bulked segregant analysis. A further testing of marker SCAR5-8 was performed using 53 early maturity individuals, 63 late maturity individuals and 70 tetraploid varieties, showing the selection accuracy 87.1% and 81.4% between marker test and phenotyping in segregation population and tetraploid varieties, respectively. Moreover, Pearson's correlation analysis also showed that the marker SCAR5-8 was significantly correlated to maturity trait in potato. The developed SCAR5-8 marker could be used in marker-assisted selection.关键词
