通过利用4个普通优质大豆品种与3个抗除草剂转基因大豆品种进行组配,采用4×3 NC II遗传交配设计,对产量、品质等性状的遗传力和配合力进行分析。结果表明:抗除草剂Bar基因能在F1代得到显性遗传,抗除草剂转基因大豆各性状以加性遗传效应为主,农大35306单株荚数和单株粒数一般配合力效应值最高,农大15751×TSB2、农大35306×TSB4等组合可作为高产优质抗除草剂组合进一步对比选择。
By using 4 common high quality soybean varieties and 3 herbicide tolerant genetically modified soybean varieties, 4 × 3 NC II genetic mating design was used to analyze the heritability and combining ability of yield, quality and other traits. The results showed that the herbicide-resistant Bar gene could be dominantly inherited in F1 generation. The additive-genetic effect was the major trait of herbicide-tolerant transgenic soybean. The average combining ability effect value of Nongda 35306 single plant pod and grain per plant was the highest, Nongda 15751 × TSB2, Nongda 35306 × TSB4 and other combinations can be used as a high-yielding and high-quality herbicide combination for further comparison and selection.
