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。 This experiment under the conditions of ordinary greenhouse, dwarf wheat × corn flowering encounter, the purpose is to carry out large-scale dwarfing wheat × maize haploid breeding work to lay the foundation. The results showed that sweet and waxy maize varieties sown in mid-January to early February in Huai’an were good in seedling emergence, light in frost damage, good in growth and development, met the normal flowering dwarf wheat flowering stage and the amount of pollen was sufficient, Which can meet the needs of larger-scale dwarf wheat × maize induced haploid breeding work.
