通过花粉母细胞减数分裂分析,鉴定了{[(T.turgidum c.v.r-80-1×H.villosa)F_1×T.aestivum c.v.宁麦7317~2)F_1×T.aestivum c.v.扬麦3号}自交和部分自由授粉后代中抗白粉病株系的染色体构型。初步探明这些材料对白粉病免疫或高抗的特性可能是通过易位或代换(单体或二体代换)导入的。这种易位与代换显然涉及载有抗白粉病基因的簇毛麦染色体。在这些材料的株系间和株系内,观察到了上述易位或代换交错存在的现象。
Through the meiosis analysis of pollen mother cells, {[(T. turgidum cvr-80-1 × H. villosa) F_1 × T. aestivum cv Ningmai7317 ~ 2) F_1 × T.aestivum cv Yangmai3} Chromosome Configuration of Powdery Mildew Resistance Lines in Selfing and Partial Free Pollination Progenies. Preliminary evidence of these materials immune to powdery mildew or high resistance may be characterized by the introduction of translocation or substitution (monomer or substitution). This translocation and substitution apparently involves the cluster of wheat chromosomes bearing the powdery mildew resistance gene. Within the strains and strains of these materials, the above phenomenon of translocation or substitution was observed.
