1982-1983年室内测定63个水稻品种的抗稻瘟性,其中抗性一号、Tetep、赤块矮选、红脚占、砦糖、宁晚一号、IR64、Milyang53、城堡一号等九个品种抗谱较广、抗性较稳定。除城堡一号外,其它的八个品种在田间叶瘟和穗颈瘟的鉴定中抗性表现均为0-3级。文中讨论了稻瘟病生理小种的致病性问题并推荐赤块矮选、城堡一号以及福建省当前大面积推广的品种77-175为福建省辅助鉴别品种。 The resistance to rice blast in 63 rice varieties was determined indoors in 1982-1983, among which resistance to Testicularity, Tetep, short dwarfism, red leg, Zhai Tang, Ning Late, IR64, Milyang53, A wide variety of anti-spectrum resistance is more stable. In addition to Castle One, the other eight varieties in the field of leaf blast and panicle blast in the identification of resistance performance are 0-3 level. This paper discussed the pathogenicity of rice blast physiological races and recommended the short-runition of red blocks, Castle No.1 and the large-scale popularized varieties 77-175 in Fujian Province as auxiliary identification varieties in Fujian Province.
