亚蔬中心绿豆品种(系)抗白粉病评价
Evaluation of resistance to powdery mildew in AVRDC mungbean varieties(lines)
【摘要】 采用苗期人工接种鉴定法,在大棚种植条件下对12个亚蔬中心(AVRDC)绿豆品种白粉病抗性进行了鉴定评价。结果显示,VC1560C、V4785和VC2768A三个品种高抗(HR)白粉病,VC6173-14、V1132为中抗(MR)白粉病品种。其它品种对白粉病表现高度感病。在田间种植条件下对亚蔬中心16个抗豆象回交9代品系(BC9)进行了成株期白粉病抗性鉴定。与对照感病品种 VC1973、VC1178A 相比,VC6459-3-6-37和 VC6458-6-3-16对白粉病具有一定抗性,但白粉病感染程度仍很严重,其它14个 BC9品系均对白粉病表现高度感病。
【Abstract】 Twelve AVRDC mungbean varieties were evaluated for powdery mildew (PM) resistance at seedling stage.Three varieties VC1560C,V4785 and VC2768A showed significantly higher resistance to PM.Two varieties,VC6713-13-14 and Vl132, were moderately resistant.Others were susceptible and highly susceptible to PM. Sixteen lines backcrossed for nine times at AVRDC (BCg),which were resistant to bruchid,were evaluated for powdery mildew resistance at adult stage.Two of them showed less susceptible than the check VC1973A and VCl178A.The others were highly susceptible to PM.
