摘要: 为了探讨小麦-冰草新种质普冰3228籽粒主要矿质元素含量的遗传特点,对普冰3228、京4839 及其F2:3群体籽粒Ca、Mg、Zn含量进行测定,并对普冰3228籽粒Ca、Mg、Zn含量进行遗传分析。结果表明,普冰3228、京4839及其F2:3群体籽粒Ca、Mg、Zn含量均存在一定的差异,F2:3群体籽粒Ca、Mg、Zn含量分别为81.76~999.55、337.24~1 380.86、5.21~148.11 mg/kg,其中Zn含量变异最大。3种元素含量具有相似的遗传特点,其最适遗传模型均为2对主基因+多基因模型,且主基因均具有加性-显性-上位性效应。控制Ca含量主基因的加性、显性、加性×加性、加性×显性、显性×加性效应值均为正值,而其显性×显性效应值为负值;控制Mg含量主基因的加性、显性、加性×加性、显性×加性效应值均为正值,而其加性×显性、显性×显性效应值均为负值;对于Zn含量,其主基因的加性、显性、加性×加性、加性×显性效应值均为正值,而显性×加性、显性×显性效应值均为负值。3种元素含量的主基因遗传率表现差异较大,其中Zn含量的主基因遗传率最高,其次是Mg含量,Ca含量最低。

Abstract: In order to dissect the genetic characteristics of major mineral element content in the new germplasm of wheat‑Agropyron cristatum derivative Pubing 3228,the contents of Ca,Mg and Zn in grains of Pubing 3228,Jing 4839 and their F2:3 population were assessed,and the genetic characteristics of Ca,Mg and Zn contents of Pubing 3228 were analyzed.The results showed that the contents of Ca,Mg and Zn in grains of Pubing 3228,Jing 4839 and their F2:3 population were different;the contents of Ca,Mg and Zn in F2:3 population were 81.76—999.55 mg/kg,337.24—1 380.86 mg/kg and 5.21—148.11 mg/kg,respectively;the content of Zn had the largest variation.The Ca,Mg and Zn contents had similar genetic characteristics,the optimal genetic model was two major genes+polygene model,and the inheritance of the two major genes had the effect of additive‑dominant‑epistasis.The effects of additive,dominance,additive×additive,additive×dominance and dominance×additive of major genes of Ca content were positive,but the effect of dominance×dominance was negative.The effects of additive,dominance,additive×additive and dominance×additive of major genes of Mg content were positive,but the effects of additive×dominance and dominance×dominance were negative. For Zn content,the effects of additive,dominance,additive×additive and dominance×additive of its major genes were positive,but the effects of dominance×additive and dominance×dominance were negative. The main gene heritability of Ca,Mg and Zn contents was greatly different,the main gene heritability of Zn content was the highest,followed by Mg content,Ca content was the lowest.
