摘要
1985—1988年,在河南洛阳对216个小麦品种(系)进行了抗麦红吸浆虫特性的鉴定。结果表明,多年鉴定抗性表现较稳定的品种有洛阳851、徐州21号、旱7859等16个。多元回归分析表明,株高、芒长、小穗密度与每穗虫量关系不大,而小麦品种扬花时内外颖开张角度则与虫量呈极显著负相关。
In 1985—1988,216 varieties of wheat were tested for resistance tothe wheat blossom midge,Sitodiplosis mosellana(Gehin)in Luoyang City,Henan Province.Results showed that 16 varieties appeared resistant for manyyears,including Luoyang851,Xuzhou21,Hart7879,etc.Analysis of multipleregression indicated that plant height,awn length and small ear density werenot correlated much to the number of midge per ear,but the open angle ofinner and outer glume at flowering period was negatively correlated to thenumber of midge per ear at significant levels.
