贵州省拥有较为丰富的作物遗传资源,有的传统种质属稀有、特有资源,是国家作物遗传多样性的重要组成部分。迄今整理、保存了以稻、油菜、玉米、小麦等为主的贵州作物种质资源2万余份。采用种质资源库(包括国家长期库、中期库和地方中短期库)与异生境繁种相结合、国家和地方两级联动、互为补充保存体系,实施种质更新和资源保护。概述了贵州省作物种质资源的保存现状和保护途径。并就加强贵州作物种质资源保护,促进交换与利用提出了建议。
Guizhou Province has abundant crop genetic resources. Some traditional germplasm resources are rare and endemic resources and are an important part of the national crop genetic diversity. So far, more than 20,000 copies of Guizhou crop germplasm resources, mainly rice, rape, corn and wheat, have been preserved. The combination of germplasm resources (including long-term national libraries, mid-term libraries and local medium-and-short-term libraries) and extra-terrestrial species is used. National and local levels are linked together to complement each other and carry out germplasm renewal and resource conservation. The conservation status and protection of crop germplasm resources in Guizhou Province are summarized. And put forward suggestions on how to strengthen the protection of crop germplasm resources in Guizhou and promote the exchange and utilization.
