摘要:

为探究北方冬麦区小麦品种春化基因组成与冬春性的关系,以北方冬麦区271份小麦主栽品种为试验材料,通过分子标记对4个主效春化基因Vrn-A1Vrn-B1Vrn-D1Vrn-B3的组成和分布进行检测,并在海南省三亚市观察田间抽穗情况,同时结合资料记载调查其冬春性特性。分子标记检测结果显示,4个显性等位基因中Vrn-D1(占27.7%)在供试品种中分布频率最高,且呈现由南向北逐渐降低趋势;显性等位基因Vrn-B1在该麦区小麦材料中分布频率较低(占3.0%);所检测材料中均不含显性等位基因Vrn-A1Vrn-B3;该麦区小麦春化基因组合主要为vrn-A1/vrn-B1/vrn-D1/vrn-B3。通过对供试小麦材料进行冬春性分析,发现部分含有显性等位基因Vrn-D1的材料需要春化才能开花结实,而包含显性等位基因Vrn-B1的小麦材料对春化的需求明显较弱。4个显性春化基因中,只有显性等位基因Vrn-D1Vrn-B1在所检测的北方冬麦区小麦品种中有分布,且显性等位基因Vrn-B1对小麦春化发育特性的作用强于Vrn-D1

Abstract:

In order to explore the relationship between the vernalization genes and winter-spring characteristics of wheat varieties in the Northern China Winter Wheat Region,271 wheat cultivars from the Northern China Winter Wheat Region were used as materials to detect the composition and distribution of four vernalization genes Vrn-A1,Vrn-B1,Vrn-D1 and Vrn-B3 by molecular markers.The heading date of these cultivars in the field was observed in Sanya,Hainan Province,and their winter-spring characteristics were investigated with the data recorded.The results showed that in this wheat region:among the four dominant alleles,Vrn-D1 (27.7%)had the highest distribution frequency in the tested cultivars and the distribution frequency decreased gradually from the South to the North;the distribution frequency of dominant Vrn-B1 alleles (3.0%)was very low in wheat materials in this wheat region;none of the test materials contained the dominant alleles Vrn-A1 and Vrn-B3;the most common vernalization gene allele combination was vrn-A1/vrn-B1/vrn-D1/vrn-B3.Further analysis of winterness-springness type of the test cultivars showed that some cultivars containing the dominant allele Vrn-D1 must be vernalized to blossom,while the wheat cultivars containing the dominant allele Vrn-B1 had a weak demand for vernalization.Among the four dominant vernalization genes,only the dominant alleles Vrn-D1 and Vrn-B1 were distributed in the tested cultivars in the Northern China Winter Wheat Region.The effect of Vrn-B1 on the vernalization development characteristics was stronger than that of Vrn-D1.

Key words: Common wheat, Vernalization gene, Winterness-springness type
