    摘要:

    二翅六道木在十堰勋西分布广泛,野生资源类型丰富,是具有地方传统的食材,在当地素有“ 神仙叶”之称,“ 勋西 神仙叶”也成为国家地理标志农产品 。本研究收集20种不同种质资源,建立资源圃,通过表型性状结合分子标记试验,开 展栽培利用价值的观测与研究,选出综合性状表现较好的5个种质材料,分别对这5份材料的新梢数量、新梢叶片数、新梢 成熟叶鲜重植物学特性进行测定,发现5号单株产叶量显著高于其他 。AFLP试验结果显示,5个样品材料相似系数介于 0. 7503~0. 8194,具有亲缘关系且有 一定遗传差异 。 以上研究结果为勋西神仙叶实现野转家规模化种植和相关科研提供 依据。

    Abstract:

    Abelia macrotera is a plant of caprifoliaceae family Abelia genus,It was widely distributed in local region,also a local traditional food materials,and it was rich in wild resource types .“yunxi Immortal Leaf”is a geographical indica- tion agricultural product validated and registered by the Ministry of Agriculture and Rural Development of the people,s Republic of china . In this study,we surveyed and collected20different germplasm resources to create a resource bed. ob- servations and research on cultivation utilization values through phenotypic traits combined with molecular marker tests . Five types were selected that had a good overall traits and their botanical characteristics of number of new shoots,number of new leaves,and fresh weight of new mature leaves were determined. Among them,It was found that plant No . 5had sig- nificantly higher leaf yield per plant than the other plants . The results of the AFLp test showed that the similarity coeffi- cients of the five sample materials ranged from0. 7503to0. 8194,The results of AFLp test showed that the similarity co- efficients of the five sample materials ranged from 0. 7503— 0. 8194,which were related and had some genetic differ- ences . The above research results provide a basis for the large-scale cultivation of yunxi shenxianye and related scientific research.
