摘要: 2016-2017年中稻开花灌浆期,麻城市出现了较长时间的高温天气,水稻高温热害严重。利用仲衍种业中稻绿色通道试验品种区域试验及生产试验观测,将观测资料采取归一化处理,分析了杂交中籼稻不同品种在高温胁迫下的表现差异,对计算结果用图示法进行了分析,总结出了耐高温品种的生育特性。

关键词: 杂交中籼稻, 高温胁迫, 耐高温, 生育特性, 产量

Abstract: During the flowering and filling period of medium rice in 2016 and 2017,heat damage in rice was serious because of the long-term high temperature in Macheng. The main contents of this paper includes the observation of the regional variety test and production test in the middle-season rice green channel test by Zoeve seed;the normalization treatment of observational data;analysis of different performance of various medium hybrid rice under high temperature stress;further analysis of calculation results with graphic method;summary of characteristics of high temperature resistant varieties.

Key words: medium indica hybrid rice, high temperature stress, high temperature resistance, growth characteristic, yield
