Genetical analysis of gene effects connected to utilizing potential soil phosphorus of common wheat are carried out through pot screening method by using a set of Chinese Spring telodisomic lines in the experiment,the results show:(1) Genes carried on different chromosome arms of Chinese Spring have different effects on the characteristics of utilizing potential soil phosphorus.

以部分中国春双端体为材料用土培盆栽法对小麦各染色体组有效利用土壤潜在磷基因的遗传分析表明：小麦不同染色体臂上所携基因对小麦有效利用土壤潜在磷特性具不同效应，在供试材料中，Ｂ组染色体所缺失的臂在缺磷下对籽粒产量的贡献较大，其中以４ＢＳ、５ＢＳ效应最强；而Ｄ组所有缺失的染色体臂及大部分Ａ组所缺失的染色体臂（除３ＡＳ、６ＡＬ外）在缺磷下则对籽粒产量有较强的抑制效应，其中以５ＤＳ、３ＤＬ及２ＡＬ、１ＡＳ的效应最
