为了摸清西藏自治区雀麦属种质资源分布及丰富雀麦属种质,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。本次考察收集到无芒雀麦、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种雀麦属种质,共计731份。其中,有《西藏植物志》未记载的新纪录34种,分别是雀麦、篦齿雀麦、总状雀麦和大麦状雀麦,特有种华雀麦1种;相较原有国家牧草种质资源的三库收集西藏地区雀麦属1种1份,极大地丰富了国家牧草种质资源库;丰富了已有记录种分布区域;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。
Abstract
In order to find out the distribution of germplasm resources in the Tibet autonomous region and to enrich the germplasm,The investigation and collection of germplasm resources of Bromus in south-central Tibet Autonomous Region were initially carried out. The survey collected 9 species of Bromus including Bromus inermis, Bromus japonicus, Bromus tectorum, Bromus sinensis, Bromus gracillimus, Bromus staintonii, Bromus pectinatus, Bromus racemosus and Bromus hodeaceus a total of 71 73 copies. Among them, there are three four new records unrecorded in "Flora of Tibet", namely, Bromus japonicas, Bromus pectinatus, Bromus racemosus and Bromus hodeaceus. Compared with the original national germplasm resources at three libraries collected in Tibet, which is 1 species of 1 copies, which greatly enriched the national forage germplasm resource pool; enlarged the existing recorded species distribution area; It laid the data and material basis for further study of wild forage resources in Tibet autonomous region, and provided raw materials for further domestication and breeding of wild pasture in Qinghai Tibet Plateau.
