一、前言作物的产量是品种(基因)与环境条件相互作用的表现。一个优良品种必须具备高产、稳产和对不同地理气候条件的适应性好的特性。本文以 S.A.Eborhart 和 W.L.Russell(1966年)提出的估计品种稳定性参数模式 y_(ij)=μ_i+β_iI_j+δ_(ij),具体为①b_i=∑y_(ij)I_j/∑I_j~2(环境作用下的回归系数)估
I. INTRODUCTION The yield of crops is the manifestation of the interaction between varieties (genes) and environmental conditions. A good variety must have the characteristics of high yield, stable yield and good adaptability to different geographical and climatic conditions. In this paper, we use the model of parameter y_ (ij) = μ_i + β_iI_j + δ_ (ij) proposed by SAEborhart and WL Russell (1966), which is ①b_i = Σy_ (ij) I_j / ΣI_j ~ 2 Regression coefficient under the effect) estimated
