| 摘 要： | 对6个杂交水稻组合及其亲本苗期14种酶的同工酶进行检测，并对其中较为清晰稳定的酶带进行了位点分析，以探讨杂种优势遗传基础。共获得了28个位点的相关资料，包括每个位点的性质、表型多态性和每个位点所编码的酶活性及酶带平均迁移率。所有供试材料在其中25个位点上均未表现出多态性，只有部分组合与其亲本在Est-4、Amy-1、Aat-2等3个位点上存在多态性，其中有81．8％的差异组合其酶带表现出共显性特征。对共显性与杂种优势的关系进行了探讨。

| Abstract: | In order to reveal genetic basis of heterosis in rice,studies were performed on isozymes of 14 kinds of enzymes in shoots for 6 hybrids and their parents;and isozyme loci were detected for isozyme bands which were clear and stable.Related data to 28 loci were acquired,which include character,phenotype polymorphism of each locus and enzyme activity,average relative mobility of enzyme bands encoded by each locus.No differences were shown among all of the experimental materials on 25 loci,and differences only appeared among 6 hybrids and their parents on 3 loci(i.e.Est 4,Amy 1,Aat 2),in which,isozyme bands of 81 8 percent combinations showed co dominance phenomena.In addition,the relationships between co dominance and heterosis were discussed. |
