| 摘 要： | 在田间条件下,1998-2001年研究22个草地早熟禾品种褐斑病抗性的差异。结果表明,年度间病害发生程度差异显著,其中2001年发病较轻,1999年发病较重,1998和2000年发病程度相近。品种间抗病性存在一定差异,年度间表现不一致,但具有相对稳定性。相对抗病的品种有America、Baronie、Impact、Odyssey和 Midnight;相对不抗病的有VB56 49、Baron、Alene、Abbey、Nottingham和SR2100。

| Abstract: | The resistance capability of 22 cultivars of kentucky bluegrass(Poa pratensis L.)against brown patch(Rhizoctonia solani K3/4Uhn) was studied by field experiment during 1998-2001.The results indicate that:(a) Acuteness of the brown patch disease was different year from year,It was severe in 1999,less so in 1998 and 2000,and light in 2001.(b) The disease resistance capability of each cultivar against brown patch is different from that of the others and different itself each year.(c) The cultivars such as America,Baronie,Impact,Odyssey,and Midnight have stronger resistance capability against brown patch than the cultivars VB5649,Baron,Alene,Abbey,Nottingham and SR2100. |
