摘　　要：为筛选耐密植大豆种质,本研究选用160份大豆种质资源为研究对象,设置高密度45万株·hm^(-2)和低密度25万株·hm^(-2)两个处理,调查R6和R8期的倒伏级别等相关耐密植性状。经过2018—2020年鉴定,筛选出茎秆强度、株高、主茎节数、节间长度和底荚高度作为大豆倒伏性的鉴定指标,鉴定出14份耐密植的种质资源,分别是Fiskeby1040-4-2、N07、N32、黑河21、黑河41、坂本早生、合交N13-333、合交N13-498、金源71、合丰42、丰收24、克09-95(棕种皮)、克09-95(黄种皮)和克14-758。In order to screen soybean germplasm tolerant to dense planting,this study selected 160 soybean germplasm resources as research objects,and set two treatments of high-density 450 000 plants·ha^(-1) and low-density 250 000 plants·ha^(-1) to investigate the lodging level and other related traits of dense planting tolerance in R6 and R8 stages.After identification from 2018 to 2020,stem strength,plant height,number of main stem nodes,internode length,and bottom pod height were screened out as identification indicators for soybean lodging.Fourteen germplasm resources tolerant to dense planting were identified,including Fiskeby1040-4-2,N07,N32,Heihe 21,Heihe 41,Sakamoto Early Growth,Hejiao N13-333,Hejiao N13-498,Jinyuan 71,Hefeng 42,Fengshou 24,Ke09-95(brown seed coat),Ke09-95(yellow seed coat) and Ke14-758.
