摘　　要：本试验在普通温棚条件下,开展矮败小麦×玉米花期相遇研究,目的是为开展较大规模的矮败小麦×玉米诱导单倍体育种工作奠定基础。研究结果表明:淮安地区普通温棚条件下,1月中旬到2月初播种的甜、糯玉米品种出苗好、冻害轻、生长发育良好,与正常播种的矮败小麦花期相遇,且花粉量充足,可以满足较大规模矮败小麦×玉米诱导单倍体育种工作的需要。In order to lay the foundation for the development big scale dwarf-male-sterile wheat xcorn induction haploid breeding work, we study the florescence adjustment of dwarf-male-sterile wheatxcorn under ordinary plastic tunnel. The results indicated that, mid-January to the beginning of February sowing seeds sweet and the glutinous corn variety in huaian area under ordinary tunnel, the corn emerges, growth is good and the freeze injury to be light, which may meet the normal sowing seeds dwarf-male-sterile wheat florescence, and the corn pollen quantity is sufficient, may meet the need of large-scale dwarf-male-sterile wheatx corn induction haploid breeding work.
