摘 要 ：本试验用50个日本普通小麦品种与兰州黑麦杂交，通过对杂种F1花粉母细胞减数分裂染色体行为进行观察，对36个组合F1的PMC染色体配对频率进行统计分析，发现农林20,沙丘小麦和农林9三个品种与黑麦杂种F1PMC染色体配对频率明显高于其它组合，分别为2.84、3.59、3.06。近似于对照组合“中国春×兰州黑麦”F1(为1.37)的两倍。认为

Abstract:50 common wheat (Triticum aestivum L.)from Japan were crossed with rye(Secale cereale L. cv Lanzhou). The meiotic observation of FI hybrids showed that Norin20, Sakyukomogi and Norin 9 had high chromosome pairing level in wheat-rye F1 hybrids. Their chromosome pairing levels as expressed by chiasmat
