【摘要】 以国家种质库中保存的不同来源的大豆同名品种满仓金及与其有亲缘关系的种质共 2 8份为实验材料 ,对其SSR分子标记及农艺性状进行比较分析 ,目的是检测种质库中保存的同名品种之间的差异程度 ,为大豆种质资源的保存、研究与利用以及构建大豆核心种质提供理论依据。研究结果表明 ,在 2 8份种质 2 3个SSR位点共检测出 15 1个等位变异 ,利用其中的 5个位点可将 2 8份种质区分开。通过对SSR数据及农艺性状的分析比较 ,发现利用两种不同类型数据对材料进行分析 ,既有相同的趋势又存在差异 ,将不同类型数据结合起来使用能比较全面地阐明品种之间的遗传关系。根据结果推测 ,全国统一编号分别为ZDD0 0 0 78、ZDD0 0 92 4的满仓金与黄宝珠和金元有密切的血缘关系 ,其他不同来源的满仓金之间差异较大 ,无遗传一致性 ,也具有保存价值。更多还原

【Abstract】 Twenty-eight soybean accessions were selected from the National Genebank,including 19 Mancangjins from various regions,9 accessions having related pedigree.The relationships between all accessions were characterized by agronomic traits and SSR markers. Base on the data came from agronomic traits and SSR,there were obvious differences between all of 28 accessions.23 SSR primers were used and 151 alleles were detected with average 6.6 alleles per locus. Analyzing all Mancangjin’s genetic relationship with Jinyuan and Huangbaozhu which are authenticatedas as the parents of Mancagjin,it is speculated that ZDD00078 and ZDD00924 are more conceivably derived from the cross between Huangbaozhu and Jinyuan.更多还原
