Genetic Diversity Analysis of Foxtail Millet
摘要
Abstract
In this study, 205 SSR primer pairs were designed from the genome sequence of foxtail millet. In which, 171 pairs could successfully amplify aimed fragment, and 149 pairs showed polymorphism. 41 foxtail millet germplasms were selected for genetic diversity analysis using 30 SSR markers. A total of 291 al-leles were detected out with an average of 9.7 per locus. The average genetic diversity index was 0.7907 for landraces and 0.7571 for improved varieties. Cluster analysis showed that the 41 foxtail millet varieties were divided into six groups at the similarity coefficient of 0.164, which were consistent with the ecotypes of these varieties.关键词
