| 摘 要： | 培育抗热性强的品种对应对气候变化,保障小麦稳产性具有重要意义。选用北方冬麦区53份主栽品种和苗头品系,于2008—2009年度分别种植在北京、石家庄、衡水、安阳和泰安5点,各点设正常温度和塑料棚热胁迫处理。结果表明,千粒重可作为抗热性筛选的简易指标。农大189、CA0518和京冬8号的产量和千粒重在正常和热处理环境中均较高,抗热性好;衡观33和CA0736的产量在正常和热处理环境中均较高,但千粒重均表现中等,抗热性较好;农大211、石麦15、济麦22、农大3432和山农2149在正常环境中的产量和千粒重均较高,但在热处理环境中产量和千粒重均较低,抗热性差。53份品种按和面时间和峰值曲线面积可分为强筋、中强筋、中筋、中弱筋和弱筋5大类。热处理使所有类型材料的蛋白质含量和籽粒硬度增加,峰值带高、8min带高和8min带宽降低,并降低强筋、中强筋和中筋类型材料的和面时间与峰值曲线面积,增加中弱筋和弱筋类型材料的和面时间与峰值曲线面积。

| Abstract: | Selection of heat-resistance cultivars is an important approach for coping climate changes as well as ensuring stable production. Fifty-three wheat (Triticum aestivum L.) cultivars and advanced lines from the North China Winter Wheat Region, planted in five locations including Beijing, Shijiazhuang, Hengshui, Anyang, and Tai’an in 2008-2009 wheat season, were used to analyze the effect of heat stress on yield nd quality traits. The result indicated that thousand-kernel weight (TKW) can be used as a simple criterion for heat-resistance selection; Nongda 189, CA0518, and Jingdong 8 performed high yield and high TKW under both normal and heat-stress treatments, and were characterized with high resistance to heat stress; Hengguan 33 and CA0736 performed high yield but medium TKW in all environments, and were characterized with good resistance to heat stress; Nongda 211, Shimai 15, Jimai 22, Nongda 3432, and Shannong 2149 performed high yield and high TKW in normal environments, but low yield and low TKW in heat stress environments, and were characterized with poor resistance to heat stress. The 53 cultivars and lines were classified into five groups including strong, medium strong, medium, medium weak, and weak gluten strength based on Mixograph Midline peak time and peak integral. Under heat stress environment, the grain protein content and hardness were increased while the Mixograph midline peak value, timex value, and timex width were decreased. The Mixograph peak time and midline peak integral for materials with medium weak and weak gluten strength were increased while they were decreased for materials with strong, medium strong, and medium gluten strength. |
