黑麦的RFLP为基础的遗传图谱提供了证据，黑麦基因组相对于六倍体小麦的多个进化易位。小麦染色体臂2RS、3RL、4RL、5RL、6RS、6RL、7RS和7RL均参与了至少一次易位。一个可能的进化途径，占今天的R基因组相对于A，B和D基因组的小麦，提出。这些结果的相关性，旨在转移有用的基因从黑麦，可能是其他相关物种，小麦的策略进行了讨论。
An RFLP-based genetic map of Secale cereale has provided evidence for multiple evolutionary translocations in the rye genome relative to that of hexaploid wheat. DNA clones which have previously been mapped in wheat indicated that chromosome arms 2RS, 3RL, 4RL, 5RL, 6RS, 6RL, 7RS and 7RL have all been involved in at least one translocation. A possible evolutionary pathway, which accounts for the present day R genome relative to the A, B and D genomes of wheat, is presented. The relevance of these results for strategies designed to transfer useful genes from rye, and probably other related species, to wheat is discussed.
