吉林省野生牧草种质资源的考察与搜集

Investigation and collection of wild forage germplasm resource in Jilin Province

搜集吉林省境内有利用价值的野生牧草种质资源,为吉林省野生牧草种质资源保护、研究和开发利用提供基础材料。2008-2009年连续2年对吉林省内野生牧草种质资源进行考察与搜集,共采集野生牧草种质资源材料191份,涵盖18科59属89种,其中,豆科91份,禾本科64份,其他科36份。这些野生牧草种质材料中既有独特的地方野生种和一些适应性强、分布广的变异种,也有不同生境条件下优良栽培牧草的野生种和野生近缘种。并初步掌握了一些重点属、种的分布规律及其与生境条件的关系。为筛选和培育优良牧草新品种提供丰富的野生种质材料的同时,也为重点野生牧草种质资源的保护和开发利用提供了科学资料。

In order to provide information on the conservation,research and development of wild forage germplasm resources,a total of 191 germplasm resources of valuable wild forages were collected during 2008-2009 in Jilin Province.The results of this study showed that the 191 germplasm resources covered 18 families,59 genera,89 species,of which 91 were Leguminosae,64 were Gramineae and 36 were other sections.In these wild forage germplasm samples there were not only unique local wild species and a number of adaptable,widely distributed,variations in species,but also wild species and wild relative species of excellent cultivated grasses in different habitats.Distribution of some key genera and species,and their relationships with habitat condition were also summarized.This study provided abundant wild forage germplasm resources for screening and cultivation of new varieties of grasses,and important scientific information on wild grass germplasm resource conservation,development and utilization.
