摘要
玉米大斑病是危害玉米叶部的主要病害之一,在世界玉米种植区域普遍发生。玉米对大斑病的抗性可分为质量性状和数量性状,前者包括9个显性基因(Ht1,Ht2,Ht3,Htm,HtP,HtNB,Htn1,NN^(c)和St)和2个隐性基因(ht4和rt),后者包括许多数量抗性基因,遍布10条染色体。本研究从病原菌特征及发病影响因素、抗病种质资源筛选、抗性机制、抗性遗传、抗性基因挖掘与定位的角度阐述玉米抗大斑病的研究进展,旨在为玉米大斑病的抗病分子机制及分子辅助育种提供借鉴。
Northern corn leaf blight(NCLB)is one of the main diseases endangering corn leaves and generally occurs in world maize-growing regions.The resistance of maize to NCLB can be divided into qualitative and quantitative resistance.The former includes 9 dominant genes(Ht1,Ht2,Ht3,Htm,HtP,HtNB,Htn1,NN^(c)and St)and 2recessive genes(ht4 and rt).The latter consists of numerous quantitative resistance genes spreading all over 10 chromosomes of maize.In this review,the recent advances on NCLB were summarized including the characteristics and influencing factors of pathogens,screening of resistant germplasm,resistance mechanism,resistance inheritance,exploitation and mapping of resistant genes,to provide reference for the molecular mechanism of resistance and molecular assisted breeding.
