研究玉米主要数量性状遗传参数,对玉米育种工作具有指导意义。数量性状的遗传行为易受环境条件的影响,取材、环境条件不同,估算的结果有一定的差异,因此我们试估了在廊坊地区环境条件下夏玉米单交种的主要数量性状的遗传力、性状间相关系数和有关选择指数等项参数,初步分析了在本区条件下夏玉米单交种主要性状的遗传动
Studying the genetic parameters of the main quantitative traits in maize has guiding significance for maize breeding. Quantitative trait genetic behavior vulnerable to environmental conditions, drawing, environmental conditions are different, the estimated results have some differences, so we tested the Langfang region under the environmental conditions of the main quantitative traits of summer maize heritability, Trait correlation coefficient and the relevant selection index and other parameters, preliminary analysis of the region under the conditions of the main traits of summer maize single genetic motion
