摘　　要：用青海高原自然条件下种植的小麦不同种、杂种、幼胚培养后代，大麦、黑麦和小黑麦的种子作发芽试验，从普通小麦及其杂种、幼胚离体培养后代和大麦中，出现了多胚苗。５９个小麦品种中只有高原６０２及２９０个普通小麦品种间杂种中有８个、１８个幼胚培养后代中有２个出现了双胚苗，出现频率虽低，但能遗传。Germinating was conduced by seeds, from the unique ecological condition in Plateau Qinghai, of different species, progencies of young embryo culture, hybrids in Triticum,barley,secale and triticale. We found polyembryonic seedlings from varieties,hybrids and progencies of young embryo culture in Triticum aestivum and barley. Respectively, 1, 8,and 2 among 59 varieties,290 interspecific hybrids of T. aestivum and 18 young embryo culture appeared biembryonic seedlings. The character of biembryonic seedling was hereditable,though its frequency was lower.
