Abstract

Cytogenetic analysis of three backcross generations of the hybrid Triticum turgidum × T. timopheevi (2n = 28) showed segregation of meiotic behaviour in each successive generation. The segregation was continuous and was possibly under control of polygenes. These results indicate that the meiotic irregularities commonly found in F₁ hybrids between T. turgidum and T. timopheevi are primarly genetically induced.
