新疆糜子种质资源遗传多样性及亲缘关系分析
Analysis of Genetic Diversity and Relationship on Millet (Panicum miliaceum ) Germplasm in Xinjiang
摘要
Abstract
[Objective] The purpose of this program is to provide theoretical basis for the breeding of high quality by investigating the genetic diversity of Panicum miliaceum in Xinjiang and their relationship. [Method] The genetic diversity and relationship of 25 materials of Panicum miliaceum from three areas in Xinjiang and five from Shanxi were analyzed by using inter - simple sequence repeat (ISSR) markers. [Result] 147 bands were amplified by 13 informative and reliable primers,of which 134 were polymorphic loci. The percentage of polymorphic loci (PPL) was 91.6%, Nei's genetic diversity(h)was 0.195, Shannon's Information index(I)was 0.32 3. UPGMA method was used to analyze the Millet cluster from four different sources. And the finding is that they all belong to one group. [Conclusion] These results show that the main genetic variation existed within the groups and there is some genetic differentiation between the ones in Xinjiang and the one from Shanxi. They can be applied to strengthen the mining of millet germplasm at the molecular level, and provide some materials for their breeding and matching of hybrid parents in the future.关键词
