【摘要】 改良大豆子粒性状的内在和外观品质是解决我国大豆生产及出口问题的重要途径。大豆重要经济性状基因的遗传及分子水平的QTL分析是大豆基因组研究的重要内容,同时进行二者的研究利于经典遗传学和分子遗传学研究的统一,并能为分子标记辅助选择和品质育种提供理论依据。大豆 SSR标记对遗传图谱的构建和图谱的进一步密集优化起着关键作用。由于大豆的基因组含有广泛的复制区和丰富的重复序列,并且种内同源性程度非常高等原因,使得其高密度遗传图谱研究落后于其它作物,因此,相对于高附加值大豆产品的重要性而言,大豆是世界上最需要加大基础遗传研究的作物之一,同时构建并优化高密度大豆遗传图谱意义重大。对国内外尚未报道过的大豆粒形性状以及大豆异黄酮及其组分进行的遗传效应及分子定位研究是改良大豆品质的重要方法。本研究为了解决以上问题有针对性地开展工作,并取得了较好的结果。更多还原

【Abstract】 The soybean (Glycine max (L.) Merr.) is not only an important economic crop but also an important food crop. Therefore, improving the internal and the external quality of the soybean is one of the important paths to resolve the soybean production problem in China, especially it is more urgent to study the seed related traits and isoflavones and its components composition in domestic and international soybean. The integration of SSR marker derived genetic map, identification of genetics effect of economically important agronomic traits and QTL analysis of seed in soybean serve the plant geneticist in a number of ways, from marker assisted selection in plant improvement to map-based cloning in molecular genetic research. Soybean is derived from ancient tetraploid and strictly self-pollinated. Its genome contains a large amount of duplication areas and repetitive sequences. The homology within the species is very high. For these reasons the research of genetic mapping in soybean is dropped behind the other crops. SSR markers play a critical role in integrating maps from different populations. One of the most important attempts in soybean genome research is to construct populations with large contents and facilities to locate special important a-gronomic traits. The results were described as followed.更多还原
