摘要
花生病害严重影响其产量和品质,抗病品种的应用是病害防治最有效的方法。为了准确有效地鉴定和利用花生抗性资源,需要运用基因技术手段来加快花生抗病品种的育成,本文介绍了花生叶斑病、黄曲霉病以及青枯病等主要病害的基因研究概况,其次归纳和总结了花生病害抗性相关分子标记的研究进展,并提出了今后基因技术和分子标记辅助育种的研究方向,最后对多种抗病基因聚合育种进行了展望。
Disease is a serious threat for the production and quality of peanut. Planting disease resistant cultivars is the most feasible method for preventing and controlling peanut diseases. In order to identify and utilize peanut germplasms with resistance efficiently and accurately, we need to use genetic technology to speed up the breeding process of peanut resistant varieties. First, we introduced the research status of disease resistance genes in peanut, including leaf spot, Aspergillus flavus, and bacterial wilt and so on. Secondly, we concluded and summarized the research status of molecular markers related with peanut disease resistance, and pointed out the research direction of gene technology and molecular marker-assisted breeding in the future. Finally, we discussed the multiple-genes pyramiding breeding for disease resistance.
