Soybean mosaic virus （SMV） is a severe disease in worldwide soybean production. A cross was made between Kefeng No.1 with broad spectrum resistance to SMV and Nannong 1138-2, a susceptible cultivar. The inheritance of resistance to SMV strain Sa prevailing in southern China was analyzed. Results of x2 test from inoculation experiment on parents F1, F2 and F3 lines showed that the resistance to strain Sa was controlled by a single dominant gene Rsa. BSA method was adopted and 900 random 10-mer primers were used to amplify total DNA from resistant pool and susceptible pool in order to obtain polymorphic bands in two bulks.16 primers could generate polymorphic bands, of which OPW-05 and OPAS-06 could generate the most stable RAPD patterns. RAPD markers OPW-05660 and OPAS-061800 were found to be linked to *** order and genetic distance were OPAS-06（1800）22.2 cM Rsa 10.1 cM OPW-05660. Southern blotting showed that both OPAS-061800 and OPW-05660 were low copy DNA in genomic DNA. OPW-05(

1993～1996 年,在田间自然虫源条件下,鉴定了39 份材料对食叶性害虫的抗性表现。结果表明,品种之间、年份之间的抗虫性有着显著的差异;品种与年份之间互作显著。大豆对食叶性害虫的抗性机制以抗生性为主,抗虫品种表现为着卵量较少、幼虫取食量减少、体重变小、死亡率增加、历期延长和蛹重减少等。在网室人工接虫条件下,大豆对斜纹夜蛾抗性的遗传,表现出主基因+ 多基因控制的遗传模式,抗性表现为显性。在不同生长时期,抗性遗传表现有所差异,主基因方差和多基因方差、主基因遗传率和多基因遗传率不同,但都存在着一对主基因。主基因的遗传率较高,一般在50% ～70% 之间,多基因的遗传率相对较低,只有10% ～30% , 抗虫性的遗传变异以主基因变异为主,多基因变异为辅。

大豆(Glycine max)是光周期敏感的植物,该特性是决定其生育期及其生态适应区的关键因素。温带的大豆品种引种到热带地区(短日照)时,开花期和成熟期提前、产量降低,限制了大豆在热带地区的种植。长童期(LJ)大豆品种的发现是解决该问题的重要突破。在短日照条件下,LJ品种比温带品种开花晚、体量大、成熟晚且产量提高。前期研究发现,J位点是控制LJ性状的关键位点。近期,我国科学家通过精细定位克隆了J基因,发现其与拟南芥(Arabidopsis thaliana)早花基因(ELF3)同源。他们通过功能互补和近等基因系等方法验证了J基因的功能,在短日照条件下,等位基因j比J开花晚、成熟晚且产量提高。进一步研究发现,J蛋白与E1基因(豆科植物开花抑制因子)的启动子结合抑制E1基因的表达,从而解除E1对大豆开花基因(FT)的抑制,促进大豆在短日照下开花。研究还发现在大豆种质资源中存在多种j等位变异。该研究引领了大豆生育期遗传研究的新方向,揭示了大豆向热带地区发展的遗传基础。
