F1 interspecific hybrids involving nine tetraploid Triticum species were studied. Some developed leaf tumours at the seedling stage. Tumorous hybrids were restricted to crosses involving either T. timopheevi or T. araraticum as one parent. The hybrids from the rest of the crosses, including those of T. timopheevi × T. araraticum, were non-tumorous. Genetically divergent and non-integrated parental species appeared to be inducing spontaneous tumour formation in their hybrids.
研究了涉及 9 个四倍体小麦物种的 F1 种间杂种。一些杂种在幼苗期出现叶片肿瘤。在涉及 T. timopheevi 或 T. araraticum 作为亲本之一的杂交中，出现了肿瘤杂种。其余杂交的杂种，包括 T. timopheevi × T. araraticum 的杂交，是非肿瘤的。遗传上分化的和非整合的亲本物种似乎在它们的杂种中诱导自发肿瘤形成。
