摘要
选用有代表性的半冬性与弱春性小麦品种各3个,在河南省22个生态试验点（北纬32°~36°）种植,分析了2类小麦品种的不同发育特性及产量构成因素在不同生态环境条件下的变化。结果表明,基因型和环境对小麦产量及其构成因素均有极显著影响。6个供试品种中,郑麦004产量最高（7 522.49 kg/hm2）,豫麦50号产量最低（6 472.12 kg/hm2）。在河南省不同生态环境下,3个半冬性品种的平均产量极显著高于弱春性品种,千粒重极显著低于弱春性品种,而穗粒数极显著高于弱春性品种。据此,对河南省小麦优质高效栽培提出了一些建议。
Three semi-winterness and three weak springness wheat varieties were cultivated at twenty-two locations（from 32°N to 36°N） in Henan province to evaluate the variation of yield and its composition property of the two different wheat types under different environments.Results indicated that both the genotype and environment had significant effect on yield and its composition property,but the effect of genotype was more pronounced than others.Among the six cultivars,The yield of Zhengmai 004 was highest（7522.49kg/ha）and Yumai 50 was the lowest（6472.12kg/ha）.Yield and grains per ear of semi-winterness wheat varieties were significantly higher than those of weak springness varieties,although 1000-grain weight of them was lower than the latter under different environment in Henan province.Some suggestions were made to improve wheat planting for higher quality and yield in Henan province.
