摘  要：
为了摸清西藏自治区雀麦属种质资源,初步开展了西藏自治区中南部雀麦属种质资源的考察和收集工作。共收集到无芒雀麦、雀麦、旱雀麦、华雀麦、细雀麦、大序雀麦、篦齿雀麦、总状雀麦、大麦状雀麦等9种73份资源。其中,发现《西藏植物志》未记载的新记录种4个,分别是雀麦、篦齿雀麦、总状雀麦和大麦状雀麦,并发现了西藏特有种华雀麦。相较原有国家牧草种质资源库保存的西藏地区雀麦属1种1份,极大地丰富了国家牧草种质资源库,为深入研究西藏自治区野生牧草资源奠定了数据和物质基础,为下一步青藏高原野生牧草的驯化与育种提供了原始材料。

摘  要：
In order to understand the geo-distribution of germplasm resources in genus of Bromus L. in the Tibet autonomous region,we conducted an action of survey and collection in south-central part of this region. Nine species in Bromus L. were found that included Bromus inermis Leyss.,Bromus japonicus Houtt.,Bromus tectorum L.,Bromus sinensis Keng ex Keng f.,Bromus gracillimus Bunge,Bromus staintonii Melderis,Bromus pectinatus Thunb.,Bromus racemosus L. and Bromus hordeaceus L.,and 73 accessions were collected. Interestingly,four species,namely Bromus japonicas,Bromus pectinatus Thunb.,Bromus racemosus L. and Bromus hordeaceus L. were not recorded in the " Flora of Tibet". In contrast to only one accession that was preserved in the national Genebank,this study provided additional germplasm resources that would be valuable in breeding for Bromus L. pasture in future.
