新疆的小麦品种(系)麦谷蛋白优质亚基分布规律研究
麦谷蛋白亚基对小麦品质有重要影响,优质亚基的利用是小麦品质遗传改良的重要途径。为了探讨新疆小麦优质亚基的分布规律,利用已开发的优质亚基和1B/1R易位系的分子标记,对新疆1242份小麦品种资源进行检测,结果表明,在新疆小麦品种资源中,优质亚基2^*、7+8、5+10、glu A3d、glu B3b、glu B3d、glu B3g的分布频率依次为20.2%、22.0%、21.9%、16.9%、14.3%、11.9%、10.3%;1B/1R易位系的分布频率为12.6%。在冬小麦品种资源中,国外品种(系)5+10、1B/1R易位系的分布频率均最高,7+8、glu B3d、glu B3g的分布频率均最...

Summary: | 麦谷蛋白亚基对小麦品质有重要影响,优质亚基的利用是小麦品质遗传改良的重要途径。为了探讨新疆小麦优质亚基的分布规律,利用已开发的优质亚基和1B/1R易位系的分子标记,对新疆1242份小麦品种资源进行检测,结果表明,在新疆小麦品种资源中,优质亚基2^*、7+8、5+10、glu A3d、glu B3b、glu B3d、glu B3g的分布频率依次为20.2%、22.0%、21.9%、16.9%、14.3%、11.9%、10.3%;1B/1R易位系的分布频率为12.6%。在冬小麦品种资源中,国外品种(系)5+10、1B/1R易位系的分布频率均最高,7+8、glu B3d、glu B3g的分布频率均最低;审定品种2^*、glu B3d、glu B3g的分布频率均最高。在春小麦品种资源中,国外品种(系)glu B3d的分布频率最高;国内品种(系)5+10、glu A3d、1B/1R易位系的分布频率最高,2^*、glu B3d的最低;审定品种2^*的分布频率最高,glu B3b、glu B3g的最低。总体来看,新疆春小麦优质亚基的分布频率总体高于冬小麦;导入LMW-GS优质亚基是新疆小麦品质进一步改良的重要方向;地方品种是LMW-GS优质亚基的良好供体。从1242份新疆小麦品种(系)中挑选出兼含多个优质亚基的冬、春小麦品种(系)各21份、24份,可在小麦品质遗传改良中加强利用。 |
