    摘要:

    青藏高原喜马拉雅地区是荞麦的起源中心,其独特的气候类型和地理位置孕育了丰富独特的野生荞麦资源。为探 明西藏地区荞麦属种质资源的群体数量以及分布情况,中国农业科学院野生荞麦资源调查队于 2020-2021 年间历时 40 d 在 西藏自治区进行了系统的资源调查与收集工作。以金沙江、澜沧江、雅鲁藏布江、尼洋河、帕隆藏布等河流为主线,在西藏的昌 都、林芝、山南、拉萨、日喀则 5 个地区采集到荞麦属野生植物种质资源 189 份(苦荞野生种 122 份、野生金荞麦 36 份、甜荞野 生种 10 份、细柄野荞麦 8 份、心叶野荞麦 5 份、金沙野荞麦资源 5 份、小野荞麦 2 份、四倍体齐蕊野荞麦 1 份),其种间性状变 异丰富且与其他地区的野生荞麦资源在性状上存在明显差异。野生荞麦有部分荞麦栽培种所不具备的优异性状,为荞麦属遗 传育种提供了宝贵的基因资源。

    Abstract:

    Himalayan region of Qinghai Tibet Plateau is the origin center of buckwheat. The specific climate and geographical location of this region enabled the appearance of abundant wild buckwheat resources. In order to uncover the populations of buckwheat and their distribution in Xizang Autonomous Region,the wild buckwheat resource investigation team of Chinese Academy of Agricultural Sciences conducted a survey and collection for 40 days from 2020 to 2021. Focusing on the important areas including Jinsha River,Lancang River,Brahmaputra River,Niyang River,Palong Zangbo and other rivers in Changdu,Nyingchi,Shannan,Lhasa and Shigatse,189 buckwheat wild plant germplasm accessions were collected in this five areas (122 Fagopyrum tataricum subsp. potanini,36 F. cymosum(Trevir.) Meisn.,10 F.esculentum subsp. ancestrale,8 F. gracilipes(Hemsl.) Dammer ex Diels,5 F. gilesii(Hemsl.) Hedberg,5 F. jinshaense Ohsako & Ohnishi,2 F. leptopodum Hedberg and 1 F.homotropicum). The abundant phenotypic variation among species collected from this region and significant difference in characteristics if compared to wild buckwheat accessions in other areas were observed. Since wild relatives of buckwheat has some elite characters,they might serve as a gene resources valuable for buckwheat breeding.
