在吉林省湿润冷凉区桦甸市进行10个玉米品种比较试验,分析品种试验产量构成效果,结果表明:在种植密度6万株/hm2条件下,产量位于前5位的品种分别为美金浓205、翔玉T68、先玉335、龙育3、吉平8。它们具有最高或者接近最高的保株率、收穗率、粒数以及百粒重。明确选择高产优质品种,必须具备优化的产量构成因素,以及较强的抗逆性和丰产性。
The comparative experiment on 10 maize cultivars in Huadian City, a humid and cool area in Jilin Province, was conducted to analyze the effect of yield on test varieties. The results showed that under the planting density of 60 000 plants / hm2, the top five varieties were USD / 205, Xiang Yu T68, Xian Yu 335, Long Yu 3, Jiping 8. They have the highest or near the highest conservation rate, the rate of erupting, the number of grains, and the weight of 100 grains. Clear selection of high-yielding high-quality varieties, must have an optimized yield components, as well as strong resistance and high yield.
