我国辣椒属种质资源研究进展

综合相关文献资料,从辣椒属起源与分布和种质资源研究与应用剖析我国辣椒属种质研究现状。辣椒属起源与分布的认识是辣椒属种质资源研究的基础,目前多数学者都承认辣椒起源南美洲,全世界有25个种,其中5个栽培种,我国分布有1个野生种。对辣椒属种质资源遗传多样性研究,有利于辣椒属种质资源的收集、保存、鉴定、创新和合理利用。DNA分子标记技术是辣椒属遗传多样性研究的重要工具,可以对辣椒属的分类、亲缘关系、辅助育种作较为精确的研究。

Progress of Research of Capsicum Germplasm Resources in China

Capsicum is very important global vegetable.This paper reviewed the research of Capsicum germplasm resources in China.It was based that we knew the origin and distributing of Capsicum to study the germplasm resource.Most researchers considered Capsicum originated in South America.All over the world,there are about 25 species and 5 cultivated,and one species in China.The study on the genetic diversity of Capsicum can benefit the conservation,classification,identification,genetic enhancement and effective utilization of the germplasm resources.DNA marker systems have developed in Capsicum to classify,genetic relation,genetic diversity and assist breeding.
