黑麦草属（Lolium）包括许多种，其中L.多年生植物亚种multiflorum，L.多年生植物亚种perenne和L.硬草作为牧草作物和杂草在世界范围内具有农业重要性。这三个物种是互育的，具有自交不亲和生殖系统的专性异交体。这种组合有助于提高遗传多样性，在向新的自然区域和农业环境扩张的过程中提供新的变异。黑麦草属物种之间的人类传播、去驯化和作物杂草杂交事件，或与其它如羊茅属（Festuca spp.），可能与它们独特的除草能力有关。此外，新的引进后的渗入可能会加速适应新的环境。大多数与黑麦草相关的杂草科学研究都集中在导致除草剂抗性的适应上，但也可能发生其他形式的适应。在这篇综述中，我们探讨了广泛的遗传变异之间的黑麦草物种和杂交与其他物种可能有助于范围的扩大，适应新的农业实践和未来预测的气候变化情景。版权所有2020作者。有害生物管理科学由John Wiley & Sons Ltd代表化学工业协会出版。黑麦草属植物种类繁多，其中L.多年生植物multiflorum，L.多年生植物perenne和L.硬果类植物在世界农业中具有重要意义。在这里，我们探讨的问题有关的含义的交配系统的黑麦草属。以及它是如何促成种群间广泛的遗传变异的。我们还讨论了与黑麦草属种内和种间杂交有关的问题，和混合的影响，在黑麦草种群和其贡献的复杂性状的快速演变，适应新的农业实践和预测的气候变化情景。
The genus Lolium comprises many species, of which L. perenne ssp. multiflorum, L. perenne ssp. perenne, and L. rigidum are of worldwide agricultural importance as both pasture crops and as weeds. These three species are inter‐fertile, obligate out‐crossers with a self‐incompatible reproduction system. This combination contributes to high genetic diversity that supplies new variants during expansion to new natural areas and agricultural environments. Human dispersal, de‐domestication and crop‐weed hybridization events between Lolium spp., or with others such as Festuca spp., are likely associated with their distinct weediness abilities. Furthermore, new introductions followed by introgression may hasten adaptation to new environments. Most Lolium‐related weed science studies have focused on adaptation leading to herbicide resistance, but other forms of adaptation may also occur. In this review, we explore how the wide genetic variation among Lolium species and hybridization with other species may contribute to range expansion, and adaptation to both new agricultural practices and future predicted climate change scenarios. © 2020 The Authors.

The Lolium genus comprises of many species, of which L. perenne spp. multiflorum, L. perenne spp. perenne, and L. rigidum are of worldwide agricultural importance. Here, we explore questions related to the implication of the mating system of Lolium spp. and how it contributed to the wide genetic variation among populations. We also discuss questions related to intra‐specific and inter‐specific hybridization of Lolium spp., and the effect of admixture among Lolium populations and its contribution to rapid evolution of complex traits, adaptation to both new agricultural practices and predicted climate change scenarios.
