中间偃麦草种质资源作为禾本科小麦族多年生麦草,是品质优良的小麦野生多年生亲缘物种。具有根系发达,生长势强,大穗多花且具有抗病、抗旱、抗寒、耐盐碱和高蛋白等优良性状。目前研究表明,改良中间偃麦草以选育粮饲兼用型多年生作物潜力巨大。本文综述了中间偃麦草种质资源在直接驯化改良、远缘杂交改良、基因组学育种研究等领域取得的进展,展望了今后的研究重点与选育策略,为中间偃麦草种质资源的改良和利用提供科学依据。
Thinopyrum intermedium, which is a perennial wheatgrass of Gramineae, is a wild relative species of common wheat. It generally develops stronger roots and shoots, larger spike and many flowers, and often represents good characters on biotic and abiotic stresses as well as higher protein content in the grains. Th. intermedium, as a target in breeding for perennial crops, has exhibited great potential in uses for grain and forage. In this paper, the achievements of direct domestication, distant hybridization with other crops, genomics-assisted breeding in Th. intermedium have been reviewed, and the future research focus and the breeding strategy have been prospected. This study can provide scientific basis for the improvement and utilization of Th. intermedium wild germplasm resources.
