【摘要】 对C IMM YT的99份硬粒小麦—节节麦人工合成种(简称合成种)的HMW-G S组成分析发现,G lu-B 1和G lu-D 1位点的变异类型比普通小麦丰富,分别有9种和12种亚基类型;筛选出含有比5+10亚基更优质的1.5+10和5+12亚基的合成种分别有8份和1份;含有优质亚基1.5+10的合成种与普通小麦杂交结实正常;对2个合成种与2个普通小麦品种的8个正反交组合F1种子电泳发现,优质亚基1.5+10在F1代能正常表达,双亲所有亚基在F1代都得到表达,表现共显性遗传.本研究为优质亚基1.5+10和5+12转育到普通小麦中奠定了基础.更多还原

【Abstract】 The HMW-GS compositions of 99 materials of the syndeme developed by CIMMYT with durum wheat and Aegilops tauschii（Syndeme in short） were explored and then Glu-B1 and Glu-D1 were found to vary in their types more rechly than those in common wheat,and contained 9 and 12 subunit types,respectively.There are 8 materials and 1 material of the syndeme screened to contain subunit 1.5+10 and subunit 5+12,which were better in quality than subunit 5+10,respectively.The syndeme materials containing the quality subunits were used to cross common wheat and their seed formation took place normally.The electrophoresis of the F₁ seeds of the reciprocal and direct crosses of two syndeme materials and 8 common wheat varieties indicated that subunit 1.5+10,a quality subunit,could normally express in F₁ and all the subunits of the male and female parents could express in F₁,and thus subunit 1.5+10 presented a co-dominant inheritance.This study laid a foundation for transforming quality subunit 1.5+10 and 5+12 into common wheat.更多还原
