中国春 phlb 突变体、中国春与 Ae.ovata 杂种 F_1花粉母细胞减数分裂中期Ⅰ每个细胞染色体交叉数分别为12.882和0.983个。说明,phlb 基因在普通小麦与 Ae.ovata 杂种中具有强的诱导部分同源配对的作用。在中国春 phlb 突变体×Ae.ovata 中有四价体、五价体及单价体少于14的细胞出现,说明 phlb 基因可以诱导普通小麦与 Ae.ovata 部分同源染色体配对,交换。又由于中国春 phlb 突变体与 Ae.ovata 杂种 F1用中国春回交获得了成功。说明利用 phlb 基因可以通过诱导部分同源染色体配对、交换,以染色体易位的方式直接把 Ae.ovata 中的有益基因导入普通小麦中。在 Ae.ovata 中没有拟 Ph1基因存在。
The number of chromosome crossover in Chinese spring phlb mutant, Chinese spring and Ae.ovata hybrid F_1 pollen mother cell metaphase I was 12.882 and 0.983 per cell, respectively. This indicated that the phlb gene had a strong role of inducing homologous pairing in common wheat and Ae.ovata hybrids. In Chinese spring phlb mutant × Ae.ovata there are tetravalent, pentavalent and monovalent less than 14 cells appear, indicating that phlb gene can induce common wheat and Ae.ovata homologous chromosome pairing, exchange. The Chinese spring phlb mutant and the Ae.ovata hybrid F1 were succeeded by Chinese Spring backcross. It shows that the phlb gene can be used to direct the common gene of Ae.ovata into common wheat by inducing homologous chromosome pairing, exchange and chromosomal translocation. No Phi gene is present in Ae.ovata.
