- 摘要:
- 为充分开发和利用优异大豆种质资源,以前期试验筛选获得的50份适应黑龙江省第二积温带生态区的骨干亲本为试验材料,系统地进行农艺性状调查并对群体的遗传相似性进行分析。结果表明:参试材料农艺性状变幅较大,变异系数不大,说明资源群体有少数极端类型品种存在;遗传相似系数分析表明50份大豆种质资源遗传同源性较大;聚类结果显示材料间差异不大,分类不明显;最终筛选得出部分株高、百粒重等重要农艺性状具有优势的品种资源。
- Abstract:
- In order to fully develop and utilize the excellent soybean germplasm resources,50 backbone parents adapted to the second cumulative temperate zone of Heilongjiang province were selected from previous experiments as test materials,and the agronomic traits were systematically investigated and the genetic similarity of the population was analyzed.The results showed that the agronomic traits of the tested materials varied greatly and the coefficient of variation was small,which indicated that there were a few extreme types of varieties in the resource population.The genetic similarity coefficient analysis showed that 50 soybean germplasm had great genetic homology.The clustering results showed that there was no significant difference among the materials,and the classification was not obvious.Finally,some varieties with good agronomic traits such as plant height and 100-seed weight and so on were screened out.
