以小麦做母本与大麦杂交结实率仅0.77％。本试验通过幼胚培养获得了杂种植株,胚培出苗率37.14％。杂种植株在形态上与小麦相似,完全自交不育。F_1体细胞染色体数目为28,和预期结果一致。花粉母细胞减数分裂中期Ⅰ每个细胞平均二价体数为0.98,单价体数为26.04。用普通小麦做父本与杂种回交,回交结实率为0.26％。 The rate of seed-setting of hybrids between wheat and barley was only 0.77%. In this experiment, hybrid plants were obtained through immature embryo culture, embryo culture seedling rate was 37.14%. Hybrid plants are similar in morphology to wheat and completely self-fertile. F 1 somatic chromosome number 28, and the expected results. Pollen mother cell meiotic metaphase Ⅰ per cell average bivalent body was 0.98, the number of units was 26.04. Using common wheat as the male parent and hybrid backcross, backcrossing seed set rate was 0.26%.
