1、农艺学现代农业科技2014年第11期山东省绿豆品种主要农艺性状调查分析及筛选研究巩法江李娜华贝贝毕海滨杨秀华(l上J东省淄博市农业科学研究院,山东淄博255000;临沂市农业高新技术产业示范区)摘要对山东省33个绿豆品种的8个农艺性状进行了调查及相关性分析。结果表明:分枝数、单位面积产量、单株荚数变异度较大,株高、荚长、主茎节数、百粒重变异度中等,单荚粒数变异度最小。籽粒大小以中粒型为主,占78.79%。单位面积产量与荚长呈极显著正相关性,与百粒重呈显著正相关性,与株高呈极显著负相关,与主茎节数呈显著负相关性。与其他性状
2、相关性不显著。株高与主茎节数、荚长与单荚粒数和百粒重、分枝数与单株荚数呈极显著正相关,株高与单荚粒数呈显著正相关,株高与单株荚数呈显著负相关。因此,在品种选育或品种改良过程中,可以根据不同绿豆品种特性和农艺性状之间的相关性,严格选择,获得高产、粒大、植株矮健的优良品种。综合33个绿豆品种各性状表现及相关性分析.获得综合性状优异、产量较高的绿豆材料3份关键词绿豆;农艺性状;相关性;筛选:山东省中图分类号$522文献标识码A文章编号1007—5739(2014)l1一oo54一O1ResearchofAnalyzingand
