利用Hobbit代换系（Triticum spelta 5A）与Hobbit杂交获得的单染色体重组系定位了小麦5A染色体上的一个抗冻基因。在该重组系样品中，用于抗冻性的基因座（命名为Fr1）与控制春化要求的基因座Vrn1完全连锁。这一结果可以用Vrn1基因座的多效性或Vrn1和Fr1之间的紧密遗传连锁来解释。进一步的详细研究是必要的，以解决这些替代假设。
SummaryA gene for frost resistance on chromosome 5A of wheat was located using single chromosome recombinant lines from the cross between the substitution line Hobbit (Triticum spelta 5A) and Hobbit. In this sample of recombinant lines the locus for frost resistance, designated Fr1, is completely linked to the locus Vrn1 controlling vernalisation requirement. The results can be explained by a pleiotropic action of the Vrn1 locus or close genetic linkage between Vrn1 and Fr1. Further detailed study is necessary to resolve these alternative hypotheses.
