摘　　要：以23个品种(系)为试验材料,在自然栽培管理条件下,对虫食数、虫食率与产量的关系以及同节同荚好豆百粒质量与其余好豆百粒质量的关系进行研究,探讨大豆食心虫与产量之间的关系。结果表明,不同品种(系)间的虫食相关性状差异极显著;虫食数与单株粒质量呈正相关但不显著,虫食率与单株粒质量呈显著负相关,虫食同节同荚好豆百粒质量与其他好豆百粒质量间差异不显著。In this paper, under natural cultivation management, the influence of number and percentage of damaged seeds on yield was investigated among 23 eultivars. And the influence between 100-grain mass with same position and pod and the rest intact seeds was investigated, too. The results showed that there were significant differences in different traits; the number of damaged seeds showed positive but not significant correlation with yield; the percentage of damaged seeds was of significant negative correlation with yield; there was no significant difference between 100-grain mass with same position and pod of the damaged seeds and the rest intact seeds.
