“高产稳产”是农业生产对优良品种的基本要求。品种的生产能力,是品种与环境共同作用的结果。品种型与环境互作效应的大小,反映了品种稳定性的好坏。区域试验是测定品种适应性的常规方法。本文按照S·A·Ebechart与W·A·Russel提出的遗传型品种稳定性参数模式,估算品种的稳定性,分析品种的适应性、丰产性和利用价值。为品种的审定推广和良种的合理布局提供理论依据。
“High and stable yield” is the basic requirement of fine varieties for agricultural production. Variety of production capacity, is the result of species and the environment together. The size of the interaction effect between varieties and environment reflects the stability of varieties. Regional testing is the conventional method of determining the suitability of varieties. In this paper, according to the stability parameter model of genetic varieties proposed by SA Ebechart and WA Russel, the stability of varieties was estimated and the adaptability, high yield and value of varieties were analyzed. Provide the theoretical basis for the validation and promotion of varieties and the rational distribution of seed varieties.
