从青海省4个县收集的60份燕麦样本中鉴别可能的重复材料,为编目和入库保存提供依据。通过名称与来源分析、形态变异性与相似性评价以及分子标记遗传多样性与冗余性鉴定,初步认为这些材料的来源不同,特性明显,遗传多样性丰富,具有一定的保存和利用潜力。但从中也发现同名材料较多,个别材料间遗传相似性较高,存在一定遗传冗余性,并鉴别出可能的重复材料,如白燕麦(1083)与白燕麦(1093)、燕麦(1225)与大燕麦(1226)等。本研究为资源工作者有效鉴别种质收集品中的重复材料、提高保种效率提供参考依据。
Sixty samples of oats collected from four counties in Qinghai Province were used to identify possible duplicates and provide basis for cataloging and storage. Through the analysis of name and origin, morphological variability and similarity, as well as the genetic diversity and redundancy identification of molecular markers, it is preliminarily believed that these materials have different origins, distinct features, rich genetic diversity and some potential for conservation and utilization. However, it was also found that there were more materials of the same name, higher genetic similarity among individual materials, some genetic redundancy and identification of possible repetitive materials such as white oat (1083), white oat (1093), oat (1225) And big oats (1226) and so on. This study provides a reference for resource workers to effectively identify the duplicate materials in germplasm collection and improve the efficiency of seed conservation.
