摘　　要：为了进一步探究小麦-簇毛麦T4DL·4VS易位系的育种利用价值,选用以T4DL·4VS易位系为亲本组配的5个F2群体为试验材料,研究了T4DL·4VS易位染色体在不同遗传背景中对小麦农艺性状的影响。结果表明,在所有组合中,T4DL·4VS易位染色体对有效穗数、每穗小穗数和穗粒数无明显影响;在与郑麦9023、周9823和绵阳26配置的3个组合中,T4DL·4VS易位染色体对株高表现出一定的正向效应;在与周9823、石4185和扬麦15配置的3个组合中,T4DL·4VS易位染色体对千粒重表现出负向效应;在与郑麦9023、周9823和扬麦15配置的3个组合中,T4DL·4VS易位染色体对穗长表现出负向效应;在与扬麦15配置的组合中,T4DL·4VS易位染色体对叶面积表现出一定的负向效应。可见在不同背景中T4DL·4VS易位染色体对农艺性状的遗传效应有所不同。It has been found that the T4DL·4VS translocation can be used in wheat breeding programs as a donor of resistance to wheat yellow mosaic bymovirus and take-all disease and can be used in wheat breeding for disease resistance.In order to further elucidate the potential application of this translocation line,five F2 population derived from crosses of the T4DL·4VS with 5 wheat varieties from different ecological wheat grown areas were used to assess the effects of the T4DL·4VS translocation on agronomic characters in different genetic backgrounds.It was found for all the used cross combinations,there was no significant difference between T4DL·4VS lines and non-T4DL·4VS lines on the number of effective spikes,the total spikelets per spike and the number of grains per spike.Positive effect of the T4DL·4VS lines on plant height was found in the background of Zheng 9023,Zhou 9823 and Mianyang 26,while negative effects were found on thousand-kernel weight in the background of Zhou 9823,Shi 4185 and Yangmai 15,on spike length in the background of Zheng 9023,Zhou 9823,and Yangmai 15,on the flag leaf area in the background of Yangmai 15.These results showed that significant variation occurred for some traits among different crosses,indicating that parent selection could lead to further improvements.
