| 摘 要： | 从5个普通大麦品种的幼胚培养中均得到体细胞再分化植株。对214棵再生植株进行了细胞学检查,发现四倍体5株,占总数的2.3%;相互易位杂合体1株,占总数的0.46%。四倍体植株虽然得到少数大而瘪的种子,但它们次年没有发芽;易位杂合体减数分裂时的染色体构型为5Ⅱ+1Ⅳ,属于两对非同源染色体间的简单易位。其余所有二倍体植株的细胞

| Abstract: | 214 plants regenerated from calli derived from immature embryos of 5 barleycultivars were studied for their cytogenetic behavior.It was found that 5 of them weretetraploid and one a zygote with reciprocal translocation,about 2.3% and 0.46%respectively of the total number of regenerated plants.The te |
