玉米品种灰色布局方法是一种科学合理的确定品种结构的评价方法,以往品种评价中多采用方差分析、稳定性分析等技术,这种分析方法所推荐的品种往往是稳产性强即在各生态类型区平均表现均好的品种,而对那些在特定地区表现突出的品种则被排除在外。随着现代化农业的发展和人民生活水平的提高,农业生产对农作物品种有了更高的要求(既要求高产又要优质、抗病等),以上方法由于自身局限性也难以同时满足多个因素的作物综合评价需要。
The gray layout method of maize varieties is a scientific and reasonable method to determine the structure of varieties. In the past, the methods of variance analysis and stability analysis were mostly used in the evaluation of varieties. The varieties recommended by this analysis method are often stable and strong, that is, Varieties with good average performance in type areas are excluded from those that excel in particular areas. With the development of modern agriculture and the improvement of people’s living standard, agricultural production has higher requirements on crop varieties (both high yield and good quality, disease resistance, etc.). Because of the limitations of the above methods, it is difficult to satisfy multiple factors simultaneously The comprehensive evaluation of crop needs.
