摘要:
为明确小麦春化基因Vrn1在黄淮南片麦区的分布情况及该基因对小麦幼苗习性、冬季抗寒性、生育期等性状的影响,利用STS分子标记对黄淮麦区136份小麦新品系的Vrn-A1、Vrn-B1、Vrn-D1这3个春化基因位点的等位变异进行了检测,比较了不同春化基因类型小麦品种在抗寒性、抽穗期以及成熟期的差异。结果表明,供试材料春化基因型主要分为2种:vrn-A1/vrn-B1/vrn-D1(占77.2%)和vrn-A1/vrn-B1/Vrn-D1b(占22.8%),在Vrn-A1Vrn-B1位点上未发现显性等位变异。不同春化基因型的品种抽穗期差异显著,携带Vrn-D1b基因的品种比春化基因全为隐性的品种平均早抽穗1.09 d;显性等位变异Vrn-D1b对小麦冬季抗寒性没有显著影响。抽穗期与成熟期呈极显著正相关,相关系数0.32;抽穗期与小麦冬季冻害显著负相关,抽穗期越早冻害越严重;显性春化基因Vrn-D1b的利用可以在不影响小麦越冬期抗寒性的同时缩短苗穗期。
