[目的]利用已报道的抗穗发芽共显性STS标记Vp1B3,筛选适宜黄淮麦区和长江中下游麦区种植的抗穗发芽白粒小麦品种。[方法]对57份黄淮麦区和长江中下游麦区的主要品种(系)及地方品种于2007年测定种子萌发指数(GI),并用标记Vp1B3对选取的品种做PCR扩增。[结果]标记Vp1B3扩增出抗性条带845、569 bp和感穗发芽条带652 bp 3种类型的片段,其频率分别为7.0%、26.3%和66.7%,且3种基因型品种之间的GI值差异均达到极显著水平。[结论]验证了标记Vp1B3能对不同品种的穗发芽抗性进行有效筛选;筛选出2份GI值<20%的白粒抗穗发芽小麦品种,丰产3号和万县白麦子,可作为穗发芽抗性育种中的有用资源。
[Objective] The objective was to research the quality evaluation of Chinese wheat variety which analyzed in Europe laboratory, discuss the quality analysis standard of different countries. [Method] Two leading varieties （Yangnong19, Jimai22） of Huanghuai wheat area from China were analyzed in Cra-w （Walloon Agricultural Research Centre）. [Result] Yannong19 corresponds to amuchstronger flour with a far better gluten quality. It could be used for bread making. It could also be used to produce good quality gluten. Jimai22 is not suitable for bread making but would probably be better for noodles production. [Conclusion] Protein results which come from NIR instrument are over estimating the content. This is probably due to the fact that Europe instruments are calibrated with European wheat.
