摘要
采用序列特异性PCR扩增技术,分析9个春化特性不同品种小麦春化基因VRN1在A、B和D基因组中等位基因的显隐性组成特性的结果表明:小麦品种‘辽春15’中春化基因VRN1的A、B和D等位基因均为显性;小麦品种‘新春2号’只在A基因组中为显性;小麦品种‘豫麦18’的D基因组中为显性;‘郑麦9023’和‘新冬18’两个品种的B基因组中为显性;‘周麦18’、‘豫麦49-198’、‘京841’和‘肥麦’4个品种的A、B和D等位基因均为隐性。
The allelic composition and characteristic of the vernalization gene VRN1 in A, B and D genomes of 9 Chinese wheat (Triticum aestivum) cultivars with different vernalization traits were analyzed using the sequence-specific PCR amplification. The results showed that the VRN1 alleles were all dominant in the A, B and D genomes of ‘Liaochun 15'; the VRN1 genes were dominant in A genome of ‘Xinchun 2', in B genome of ‘Zhengmai 9023'and ‘Xindong 18', and in D genome of ‘Yumai 18', respectively; the VRN1 alleles were all recessive in A, B and D genomes of ‘Zhoumai 18', ‘Yumai 49-198', ‘Jing 841' and ‘Feimai'.
