| 摘 要： | 为了解小麦品种间耐迟播性的差异，以扬麦16、扬麦18、扬麦20、镇麦9号、宁麦14和镇麦168等6个淮南麦区主栽小麦品种为材料，研究了不同播期（11月8日、11月15日、11月22日和11月29日）下小麦品种的产量、生育特性及抗逆性特点。结果表明，随播期的推迟，6个小麦品种产量均呈下降趋势，其中扬麦18和镇麦9号四个播期的产量均在4 500 kg·hm-2以上，表现出较好的丰产性和耐迟播性；扬麦18对赤霉病的抗性最强，但生育期长（190~206 d），成熟期最晚推迟至6月6日，且田间出现倒伏现象。综合来看，本试验条件下，淮南麦区小麦适播期为11月8日至11月15日，11月22日是最晚临界期。镇麦9号综合农艺性状较好，适宜淮南麦区晚播种植。

| Abstract: | To know the difference of wheat cultivars to late planting, six major wheat varieties (Yangmai 16, Yangmai 18, Yangmai 20, Zhenmai 9, Ningmai 14, and Zhenmai 168) were planted at four sowing dates of Nov. 8, Nov. 15, Nov. 22 and Nov. 29, the characters of yield, growth and development, and resistances to stresses were studied in this study. The results showed that, with the delay of the sowing date, the yield of all wheat varieties decreased. The yield of both Yangmai 18 and Zhenmai 9 was over 4500 kg·hm-2 in the four sowing dates, which indicated that they had better yielding ability and resistance to late planting. Although Yangmai 18 had the strongest resistance to FHB, but it had the longest growth period with 190~260 d in the four sowing dates, the mature period was delayed to June 6 and it was the sole variety with certain lodging. In the condition of this study, it showed that Nov. 8 to 15 was the suitable sowing date in Huainan wheat area of Jiangsu province. November 22 was critical date for late planting in Huainan wheat area. Zhenmai 9 had better comprehensive agronomic traits and adaptability to date planting in Huainan. |
