采用ADM遗传模型对不同玉米自交系开花后叶片保绿度衰减特性遗传效应进行研究。结果表明,不同自交系叶片保绿度衰减起始时间(Ts)、最大衰减速率出现时间(TVmax)、最大衰减速率(Vmax)均存在显著的遗传与环境互作效应,自交系叶片保绿度衰减特性在不同环境条件下的表现具有明显差异。利用包括基因型与环境互作效应在内的遗传分析方法,可以更清楚地发现不同亲本叶片保绿度衰减特性的遗传效应差异,有利于筛选出具有较大遗传效应的自交系,用于玉米叶片保绿度性状的改良。
Adopting the ADM genetic model to study the genetic effect of leaf green degree attenuation characteristics after flowering of different maize inbred lines. The results showed that there were significant genetic and environmental interaction effects on the greening degree decay initiation time (Ts), maximum decay rate (TVmax) and maximum decay rate (Vmax) in different inbred lines. Inbred lines Green degree attenuation characteristics under different environmental conditions have obvious differences. Using genetic analysis including genotype and environment interaction effects, we can find out more clearly the genetic effects of different parents’ green-leaf attenuation characteristics, which can be used to screen inbred lines with greater genetic effects for Improvement of Green Degree of Maize Leaves.
