摘　　要：大豆食心虫是危害大豆的世界性害虫,严重影响大豆的产量和品质。试验以69个品种(系)为材料,研究大豆食心虫侵食大豆不同高度豆荚和豆粒部位对产量的影响。结果表明,不同品种(系)的虫食相关性状差异极显著;最高与最低虫食荚位之差占株高的比例与单株粒重呈显著负相关;虫食荚位高度小于40cm与单株粒重呈极显著负相关;株高100～120cm的产量较株高小于100cm和大于120cm的产量高;食心虫侵食豆粒时较少侵食豆脐。Soybean pod borer is one of the main soybean pests in the world.It severely affected soybean yield and quality.In this paper,the influence of damaged pods at different height on the soybean yield was investigated with 69 cultivars.The results showed the significant difference in different traits of 69 cultivars.The proportion of the plant section bearing the damaged pods was demonstrated the significantly negative correlation with the product yield.The height of damaged pods at lower than 40cm was of significantly negative correlation with the yield.The yield of plants with height at 100-120cm was higher than those with the height shorter than 100cm or higher than 120cm.Hilums were rarely attacked by soybean pod borers.
