摘要: 为了解小麦春化基因Vrn-1的遗传效应,以15个不同类型的小麦品种为试材,研究了不同春化处理对小麦发育进程的影响,并采用分子标记鉴定了上述品种的Vrn-1等位基因组成。结果表明,不同Vrn-1等位基因组合的小麦品种抽穗期存在很大差异;3个显性Vrn-1等位基因的遗传效应表现为Vrn-A1>Vrn-D1>Vrn-B1;春化基因具有累加效应,显性Vrn-1基因的存在使基因型呈现春性特征,不携带任何显性Vrn-1基因的基因型则表现为冬性。因此,采用春化基因分子标记可以很好地预测品种的冬春性。

Abstract: In order to understand the genetic effect of vernalization gene Vrn-1, the effect of vernalization treatment on development of 15 wheat cultivars was studied,and the allelic composition of the Vrn-1gene in 5A,5B and 5D genomes in above cultivars were analyzed using the sequence-specific PCR. The results indicated that there is significantly difference in heading stages of genotype with different Vrn-1allele combinations. The genetic effect of three dominant Vrn-1alleles is follows: Vrn-A1>Vrn-D1>Vrn-B1: the vernalization genes have additive effects, the presence of a dominant Vrn-1allele in any genotype confers spring growth habit,whereas the presence of recessive alleles in the homozygous state confers winter growth habit. Therefore, the winter-spring character of cultivars can be confirmed according to the combination of vernalization genes.
