Crop wild relatives (CWR, plural CWRs) are those wild species that are regarded as the ancestors of our cultivated crops. It was only at the end of the last century that they were accorded a high priority for their conservation and, thus, for many genebanks, they are a new and somewhat unknown set of plant genetic resources for food and agriculture. After defining and characterizing CWR and their general threat status, providing an assessment of biological peculiarities of CWR with respect to conservation management, illustrating the need for prioritization and addressing the importance of data and information, we made a detailed assessment of specific aspects of CWRs of direct relevance for their conservation and use. This assessment was complemented by an overview of the current status of CWRs conservation and use, including facts and figures on the in situ conservation, on the ex situ conservation in genebanks and botanic gardens, as well as of the advantages of a combination of in situ and ex situ conservation, the so-called complementary conservation approach. In addition, a brief assessment of the situation with respect to the use of CWRs was made. From these assessments we derived the needs for action in order to achieve a more effective and efficient conservation and use, specifically with respect to the documentation of CWRs, their in situ and ex situ, as well as their complementarity conservation, and how synergies between these components can be obtained. The review was concluded with suggestions on how use can be strengthened, as well as the conservation system at large at the local, national, and regional/international level. Finally, based on the foregoing assessments, a number of recommendations were elaborated on how CWRs can be better conserved and used in order to exploit their potential benefits more effectively.

改善作物野生亲缘植物的保护和可持续利用所需的主要挑战和行动。

作物野生近缘种（CWR，复数CWR）是那些被视为我们栽培作物祖先的野生物种。直到上个世纪末，它们才被列为保护工作的重中之重，因此，对于许多种质库来说，它们是用于粮食和农业的一种新的且鲜为人知的植物遗传资源。在定义并表征了CWR及其一般威胁状况之后，提供了CWR在保护管理方面的生物学特性评估，说明了优先次序的需要并解决了数据和信息的重要性之后，我们对CWR的特定方面进行了详细评估。与它们的保存和使​​用直接相关。这项评估辅以对水冷堆保护和使用现状的概述，包括有关就地保护，种质库和植物园中的非原生境保护的事实和数据，以及原生境和非原生境保护相结合的优势（所谓的补充保护方法）的事实和数据。此外，对使用CWR的情况进行了简要评估。从这些评估中，我们得出了采取行动的需求，以实现更有效，更有效的保护和利用，特别是在CWR的文档记录，原位和非原位以及互补性保护以及它们之间如何协同作用方面。可以获得组件。审查结束时就如何加强使用以及在地方，国家和地区/国际层面上的整个保护体系提出了建议。最后，
