摘要: 根据2008～2009 年山西省春播特早熟玉米区域试验汇总资料, 采用主效应值、高稳系数、变异系数、标准差比数、回归系数等多种方法对长单525特早熟玉米杂交种进行了分析。结果表明: 该品种是一个丰产性好、稳定性强、适应性广, 适合在山西春播玉米特早熟区、太行太岳冷凉山区、中南部夏播区以及国内相应生态区域大面积生产应用的优良玉米杂交种。

Abstract: In this paper, according to the results of spring sowing special early mature maize regional tests in Shanxi province during 2008- 2009, special early mature maize hybrid “Changdan 525” was analyzed. A lot of analysis methods were adopted including the main effect amount, coefficient of variability,reliability of standard deviation, regression coefficient, high and stable coefficient and so on. The results showed that it's a good maize hybrid and had large crop potentiality, high and steady production and wide adaptation.It was adapted to be widely sowed in spring maize early mature regions in Shanxi province ,Taihang and Taiyue regions ,summer sowing regions and other corresponding ecological regions.
