摘要
以溧水中子黄豆和南农493-1杂交衍生的504个正反交F2:4家系为研究对象,于2008年在江苏南京和山东临沂两地种植,鉴定其株高表型。采用多QTL联合分析方法进行QTL分析,检测到株高存在环境效应和细胞质效应,定位了15个主效QTL、2个与环境互作的QTL和6个与细胞质互作的QTL。将Soybase数据库中信息完全的90个株高QTL和本研究检测的株高QTL映射到大豆公共图谱soymap 2上,利用BioMercator 2.1软件进行Meta分析。结果表明:分布于C2、F、L和M染色体上的18个较小置信区间存在一致性QTL,其中包括本研究发现的C2染色体上的qPH-6-2、qPH-6-3和M染色体上的qPH-7-1、qPH-7-2、qPH-7-3共5个QTL。
The plant height for 504 F2：4 families derived from direct and reciprocal crosses between Lishuizhongzihuangdou and Nannong 493-1 were measured at Jiangpu experimental station of Nanjing Agricultural University and Linyi experimental station in 2008,respectively.Multi-QTL joint analysis was adopted to detect QTL for the trait.The results showed that environmental and cytoplasmic effects were important for soybean plant height,and fifteen main-effect QTL,two environmental interactions and six cytoplasmic interactions were detected.The above QTL and ninety complete information QTL from Soybase data-base were collected to carry out Meta analysis using the software of BioMercator 2.1.Eighteen consensus QTL were identified,including qPH-6-2 and qPH-6-3 on chromosome C2,and qPH-7-1,qPH-7-2 and qPH-7-3 on chromosome M in this study.
