摘要
对30份产于四川的四倍体小麦地方品种(T.TurgidumL.)的酯酶同工酶分析表明,四倍体小麦的幼苗、剑叶和幼穗间酯酶同工酶存在较大差异。其中,幼苗有14条带,12种类型;剑叶15条带,13种类型;幼穗13条带,11种类型。3次测定合并分析,则产生21种类型。若仅以1次测定看,多样性指数以剑叶最高,为0 1119,说明剑叶酯酶同工酶能更好地反映其遗传多样性。同时酯酶同工酶的差异证明,来源相同又同名但原始编号不同的两份"棒棒南麦"和两份"早佐"具有不同的基因型,应视为不同的品种。
The esterase isozymes of 30 tetraploid wheat landraces (T.Turgidum L.) from Sichuan were studied. The results are as follows: Significant differences of esterase isozymes are detected in all of seedlings, flag leaves and young spikes. There are 12 zymogram types with 14 bands in seedlings, 13 types with 15 bands in flag leaves, and 11 types with 13 bands in young spikes. The three tests amount to 21 zymogram types altogether. However, polymorphic index (PI) of flag leaves is the highest in the three tests, namely 01119. The result indicates the esterase isozymes of flag leaves express various genotype genetic polymorphism much better than the others. In this study, two 'Bangbangnanmai' and two 'Zaozuo' from the same original places with different primitive numbers respectively, are regarded as different varieties, because of the different esterase isozymes.
