摘要
花生是世界上重要的油料作物之一。与栽培种相比,花生野生种具有较高的遗传多样性,能够适应一系列复杂环境,是抵抗生物胁迫和非生物胁迫的重要基因来源。多项研究表明,花生野生种对根结线虫病、晚斑病和锈病具有较高抗性。本文综述了野生花生的种类以及花生栽培种起源种相关研究进展,总结了野生花生对花生病害的抗性以及在育种中的应用。结合花生基因组学最新研究,展望了花生野生资源的利用前景。
Peanut is one of the most important oil crops in the world.Up to now,81 Arachis species are identified and arranged in 9 infrageneric taxonomic sections according to its morphological characteristics,geographical distribution and cross-compatibility.Cultivated peanut has a very narrow genetic base,which is a fundamental limitation to crop improvement using only cultivated germplasm.Compared with cultivars,wild peanut species have high genetic diversity,can adapt to a series of complex environments and are important sources for resistance to biotic and abiotic stress.An increasing number of studies showed that many wild species of peanut were highly resistant to root-knot nematode,late leaf spot and rust.In recent years,new tools for genetic and genomic analysis,provided better efficiency in using peanut resources in crop improvement.This paper reviewed the wild species of peanuts and introduced the wild peanut with disease resistance to assist the genetic improvement of peanut.
