摘要
文章概述了核心种质的提出背景、主要特征和最新研究进展,介绍了基于表型性状数据和分子标记数据的构建广西甘薯核心种质的方法,认为在利用表型性状数据进行核心种质构建时,适当地结合ISSR标记等数据进行分析,才能更好地揭示甘薯种质之间的遗传关系,从多个角度对整个甘薯资源进行评价。此外,核心种质的构建是一个动态变化的过程,应及时更新核心种质。
The present paper summarizes the concept,characteristics and latest research developments in core germplasm collection.Two methods for constructing a core collection of sweet potato germplasm in Guangxi were outlined.One method is based on phenotypic characters,while the other one is based on molecular markers.In order to reveal the genetic relationship amongst sweet potato germplasm and assess the whole sweet potato germplasm from several aspects,the method for constructing a core germplasm collection which is based on phenotypic characters should be combined with the one that is based on ISSR molecular markers.Furthermore,the core germplasm collection should be updated timely be-cause it is in constant change.
