培育小麦谷蛋白亚基近等基因系的两种方法

为研究麦谷蛋白亚基对小麦加工品质的影响,进行高分子量麦谷蛋白亚基近等基因系的创制期间,结合常规育种实践总结了两种高效培育小麦谷蛋白亚基近等基因系的新方法,以期拓宽近等基因系的培育技术,推动小麦品质研究和育种的发展。（1）SDS辅助选择的分株回交技术。该方法利用小麦自花授粉和分蘖特性,借助SDS-PAGE室内辅助选择目标亚基植株,结合经典近等基因系培育方法,提高了非直观性状基因近等基因系的培育成功率。（2）借助SDS辅助选择,并结合大田系谱育种技术而形成的杂合系谱法。本方法结合大田常规系谱育种,借助SDS-PAGE辅助选择目标亚基株系,同一组合内大量培育双亲中间类型遗传背景的近等基因系,较大的提高了培育效率。

Two Ways of Developing Wheat HMW Glutenin Subunits Near-isogenic Lines

During developing high molecular weight glutenin near-isogenic lines to study the effect of HMW glutein subunits loci on proceeding quality in wheat, two new ways were sum up to develop HMW loci near-isogenic lines on the basis of conventional breeding method, in order to expand breed technique of wheat NIL and promote quality research of wheat. (1) Method of individual plant backcross assisted by SDS-PAGE. This method,utilizing self-pollination and tiller characteristic of wheat, choose the goal subunits w...
