以我国本土玉米品种利民33、农华101、鑫鑫1号、鑫鑫2号为试验材料,以先玉335为对照品种,比较研究了不同玉米品种间产量及农艺性状等方面的差异。结果表明:对照品种先玉335稳产性仍然较好,不足在于其抗倒性略差,易出现倒伏;利民33和鑫鑫1号与先玉335产量差异不显著,鑫鑫2号的产量显著低于先玉335,鑫鑫系列品种的株高、穗位高相对较低,但叶面积指数也较低,利民33的叶面积指数和收获指数较高,但干物质积累量无优势;农华101产量表现最好,达到了“吨粮”水平,且在叶面积指数、干物质积累及茎秆抗倒性能上均体现出明显优势,在吉林省东部湿润区种植具有高产潜力。
Taking Maize 33, Nonghua 101, Xinxin 1 and Xinxin 2 as domestic maize varieties as test materials and Xianxu 335 as control varieties, the differences of yield and agronomic traits among different maize cultivars were compared. The results showed that the stability of Xiangyu 335 was still good, but the disadvantage was that its lodging resistance was slightly worse and prone to lodging. The yield of Limin 33 and Xinxin 1 and Xianxu 335 was not significantly different. The yield of Xinxin 2 Significantly lower than the Xian Yu 335, Xin Xin series of plant height, ear height is relatively low, but the leaf area index is also low, Leemin 33 leaf area index and harvest index higher, but there is no advantage of dry matter accumulation ; Nonghua 101 showed the best yield and reached the level of “t he grain”, and showed obvious advantages in leaf area index, dry matter accumulation and stem lodging resistance. In the eastern humid zone of Jilin Province, potential.
