摘　　要：采用种间杂交 (硬粒小麦×普通小麦 )创造了具有高分子量谷蛋白 5 +12亚基的稀有小麦新品系 ,SDS PAGE分析表明 ,该品系的Glu D1位点编码 5 +12亚基。其沉降值、湿面筋含量、粉质仪图形成时间、稳定时间等品质指标显著优于具有优质亚基 5 +10的姊妹系 ,该小麦品系遗传上纯合 ,具有多花多粒的优良农艺性状。 5 +12亚基稀有小麦新品系的创造 ,将为小麦品质育种提供新的优质遗传资源。A new bread wheat line possessing high molecular weight glutenin subunits(HMW GS) 5+12 was developed by interspecific cross ( T. durum Desf.× T.aestivum L.). The SDS PAGE analysis demonstrated that this new germplasm possessing HMW GS 5+12 at Glu D1 locus. Lines possessing HMW GS 5+12 subunits were superior in many quality parameters, sedimentation value, wet gluten content, development time and stability time of farinograph as compared to their siblines containing HMW GS 5+10. This novel line had high yielding characters with multi florets, and would be a potential genetic resource for bread wheat quality breeding.
