油茶炭疽病抗病机制及抗性育种研究进展

Progress in the resistance mechanism and breeding of Camellia oleifera with resistance to anthracnose

油茶(Camellia oleifera)是我国重要的木本油料作物,油茶籽油具有极高的经济价值。炭疽病是油茶最主要的病害之一,在油茶各产区广泛传播,使油茶植株的生长发育受到限制,油茶籽油的产量受到影响。近年来,随着油茶产业的快速发展,油茶炭疽病的相关研究也取得了很大进展。本文从油茶抗炭疽病机制、抗病关键基因挖掘及种质资源评价等方面进行了综述,为油茶炭疽病防治和油茶抗炭疽病种质创新提供了理论依据和参考。

Camellia oleifera is an important woody oil crop in China,and its seed oil has a high economic value.Anthracnose,one of the main diseases in C.oleifera,occurs in a wide range in the production areas,limiting the growth and development of plants and causing serious losses of oil production.With the rapid development of the C.oleifera industry in recent years,great progress has been achieved in the research on anthracnose in C.oleifera.This paper summarized the resistance mechanisms,the mining of resistance genes,and the evaluation of resistant germplasm resources,aiming to provide a theoretical basis for the prevention and control of anthracnose and the breeding of C.oleifera germplasm with resistance to anthracnose.
