以山羊草属节节麦作母本,普通小麦、二粒系小麦、黑麦及小黑麦分别作父本杂交,将授粉后不同天数的幼胚取下,在无菌条件下接种于试管内培养。共接种101个杂交组合的1090个幼胚,分化成全苗的31个(2.84％),无根小苗20个(1.83％),类苗24个(2.2％)、愈伤组织66块(6.05％)未分化的950个(87.16％)。在31个全苗中包括普通小麦的21株、二粒系小麦的5株、黑麦的2株、小黑麦的3株。试验说明,用二倍体节节麦作母本,借助于幼胚培养,也可以获得远缘杂种。 The male parent of Aegilops schizophyllum was used as the male parent, the common wheat, the second wheat, the rye and the triticale were crossed respectively, and the young embryos of different days after pollination were removed and inoculated into the test tube under aseptic conditions to cultivate. A total of 1090 immature embryos of 101 hybrids were inoculated into 31 (2.84%) full seedlings, 20 (1.83%) rootless seedlings, 24 (2.2%) seedlings and 66 callus (6.05% ) Undifferentiated 950 (87.16%). Among the 31 whole seedlings, 21 were common wheat, 5 were double grain wheat, 2 were rye and 3 were triticale. Test shows that the diploid section of wheat as the mother, with the help of immature embryo culture, but also can obtain distant hybrids.
