4个茶树品种自交后代群体遗传结构分析
Genetic Structure of Natural Hybrids of Four Tea Varieties
摘要
Abstract
EST-SSR was used to analyze the genetic polymorphism,relationship,and population structure of Zimeigui,Jinmudan,Mingke 1 (Jinguanyin),Yuemingxiang,and the natural hybrids of Zimeigui,Jinmudan, Jinguanyin,and Yuemingxiang. A total of 125 alleles were amplified using 16 pairs of EST-SSR primers. The average PIC was 0.617, varying from 0.159 to 0.840. The average observed heterozygosity, expected heterozygosity,Nei′s genetic diversity,Shannon information diversity index among them were 0.579,0.639, 0.632,and 1.281,respectively. A strong maternal parental effect seemed apparent as shown by the genetics of the natural hybrids. The population structures of the 4 groups had distinctive genetic characteristics. It was concluded that the software applied could be adequately used for analyzing the genetic structures of tea populations.关键词
