Developing a new wheat germplasm possessing High-Molecular-Weight glutenin subunits, 5+12.

摘要

A new wheat line possessing high-molecular-weight glutenin subunits(HMW-GS) 5+12 was developed by using interspecific cross (T.durum Desf. x T.aestivum L). The SDS-PAGE analyses demonstrated that this new germplasm possessing HMW-GS 5+12 at Glu-Dl loci. Lines possessing HMW-GS 5+12 subunits were superior in many quality parameters, sedimentation value, wet gluten, developing time and stability time of farinograph as compared to their siblings containing HMW-GS 5+10. This novel line has high yieldingcharacters in multi-florets, and can be a very useful genetic resources for wheat quality breeding.
