摘要
[目的]了解武运粳23号对水稻条纹叶枯病的抗性,为该品种的推广应用提供参考。[方法]通过从育秧到收割全程的综合性状评价研究了武运粳23号对水稻条纹叶枯病的抗性。[结果]武运粳23号虽然在秧田期承载的灰飞虱成虫量高,但对条纹叶枯病菌表现出较强抗性,整个生育期基本未见条纹叶枯病病株,也未发生黑条矮缩病,并且对后期褐飞虱具有一定的抗性。[结论]在水稻条纹叶枯病流行年份,武运粳23号具有广阔的推广应用前景。
[ Objective ] The aim was to understand the resistance of Wuyunjing 23 to rice stripe disease to provide reference for popularizationand application. [ Method] The resistance of Wuyunjing 23 to rice stripe disease was studied through comprehensive character evaluation fromseedling culture to harvest. [ Result] Wuyunjing 23 had high burden quantity of Laodelphax striatellus adults, but it had higher resistance torice stripe disease. There was little rice stripe disease and rice black-streaked dwarf disease strains, furthermore it had certain resistance forrice plant hoppers in later rice.
