摘要
三江并流区域是指怒江、金沙江和澜沧江在云南省境内并流而不交汇的横断山脉纵谷地带,拥有丰富的植物资源。为了摸清该区域荞麦种质资源的分布情况,中国农业科学院作物科学研究所野生荞麦考察队于2020-2022年对该地区进行了野生荞麦调查和收集工作,共收集了荞麦属下属的8个种60份材料。调查结果表明,金沙江流域是三江并流区域中野生荞麦种类最丰富的地区,金荞麦和细柄野荞麦是分布范围最广的野生荞麦,其他野生荞麦的分布具有明显的地域性,在调查中发现了再生能力强型、多花多分枝型细柄野荞麦、多花多分枝型心叶野荞麦和粉红花色型金荞麦4种特殊的野生荞麦资源。调查结果对该地区荞麦属种质资源的针对性保护和利用奠定了坚实基础,同时也为荞麦的起源驯化研究提供了一定的参考。
The Three Parallel Rivers of Yunnan Protected Areas refers to the longitudinal valley of the Hengduan Mountains where the Nu River,Jinsha River and Lancang River flow in parallel in Yunnan province,and has rich plant resources.In order to find out the distribution of buckwheat germplasm resources in this area,the wild buckwheat expedition team of the Institute of Crop Science of the Chinese Academy of Agricultural Sciences conducted a 15-day wild buckwheat survey in the area from 2020 to 2022,collected a total of 60 materials from 8 species of the genus Fagopyrum Miller.The survey results show that the Jinsha River basin has the most species of wild buckwheat in the Three Parallel Rivers of Yunnan Protected Areas.Fagopyrum cymosum and F.gracilipes have the widest distribution range,and the distribution of other wild buckwheat had obvious regional characteristics.Four kinds of special wild buckwheat resources were found,which were F.gracilipes with strong regenerative ability,F.gracilipes with multi-flowered and multi-branched characteristics,F.gilesii with multi-flowered and multi-branched phenotype,F.cymosum with pink flowers.The survey results laid a solid foundation for the targeted conservation and utilization of buckwheat germplasm resources in this region,and provided certain reference value for the study of the origin and domestication of buckwheat.
