中文摘要：

为了提高小麦在江汉平原的产量,研究了39个小麦（Triticum aestivum L.）品种不同生育时期（拔节期、孕穗期、开花期、灌浆中期）渍水后对小麦子粒产量的影响,并以每盆子粒产量、渍水后产量降低比例作聚类分析,以筛选出耐渍高产的小麦品种。结果表明,在拔节期小麦产量受渍害的影响较小,渍水后单株产量为7.11～17.17 g;其余3个时期渍水对产量均有较大影响,其中孕穗期渍水后单株产量为5.54～13.30 g,开花期渍水后单株产量为3.61～14.76 g,灌浆中期渍水后单株产量为4.21～16.59 g。对4个生育时期小麦受渍后子粒产量及其产量降低比例的聚类分析结果进行综合分析,筛选出3个耐渍性较高的品种,分别为扬麦11、扬麦16、郑麦9023,这3个品种在拔节期至成熟期均有较高耐渍性,可在江汉平原推广。

英文摘要：

To increase the yield of wheat（Triticum aestivum L.） in the Jianghan Plain, the yield of 39 wheat varieties tested in different periods（the jointing stage, booting stage, filling stage, blossom stage） were studied. Cluster analysis of yield reduction percentage per pot after waterlogging was carried out to screen wheat varieties with the waterlogging-tolerant and high-yield. The results showed that wheat yield at jointing stage affected by waterlogging waterlogging with yield per plant of 7.11～17.17 g, yield per plant of 5.54～13.30 g at booting stage after waterlogging, yield per plant of 8.08～14.76 g at blossom period after waterlogging, yield per plant of 4.21～16.59 g at filling stage waterlogging. According to the cluster analysis of the 4 stages of wheat waterlogging, Yangmai 11, Yangmai 16, Xiangmai 20, Xiangmai 55, Zhenmai 9, Zhengmai 9023 were selected. The 6 varieties above have high yield with waterlogging tolerance and could be popularized in the Jianghan Plain.
