SRAP分子标记分析广西糯玉米地方品种的遗传多样性
Genetic diversity analysis of glutinous maize landraces by using SRAP molecular markers
摘要
Abstract
[Objective]In this research, the genetic diversity of Guangxi glutinous maize landraces was studied and the preliminary taxa classification was conducted in order to provide reference for the improvement and innovation of glutinous maize germplasm. [Method]Utilizing the SRAP molecular markers technology, the genetic diversity and heterosis group divisions of 49 glutinous maize landraces in Guangxi were analyzed. [ Result ]The 49 glutinous maize landraces were divided into 5 groups, in which Guangxi, Western and Northern Guangxi areas in particular, had an abundant genetic diversity of glutinous maize landraces. Varieties in most parts of Baise and Hechi region were divided into the same group since these glutinous maize landraces had strong regional characteristics, that is, these glutinous maize landraces from the same area were closely related genetically. Also, the glutinous maize landraces in the neighboring Baise and Hechi areas exhibited strong phylogenetic relationship. [Conclusion]The Guangxi glutinous maize landraces displayed rich genetic diversity, and the geographic origin and geographical environment had significant relationship on these genetically related landraces.关键词
