高低两种密度条件下耐密植优异大豆种质鉴定
- Title:
- Identification of Excellent Soybean Germplasm Tolerant to Dense Planting under High and Low Density Conditions
- 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Fiskeby104042、N07、N32、黑河21、黑河41、坂本早生、合交N13333、合交N13498、金源71、合丰42、丰收24、克0995（棕种皮）、克0995（黄种皮）和克14758。
