文章认为,丰产性、丰产重演性、适应性及稳定性四者,是品种主要生产性能的最高表现,应作为品种区域试验的主要决选指标;并均应统一以适当参数加以定量表述,从而使总结评定共同建立在对参试品种的科学分类基础之上。本文建议,区试中意义准确、完整的丰产性,应按以下三参数合并表述,即:经过相应加权校正的(平均)丰产水平Yi/以对照品种为参照物兼示差异显著性的丰产指数I_Y*,**/兼示邻位差异显著性的丰产位次N*,**;对区域化鉴定中具关键作用之丰产重演性,建议分作不同可靠程度的增产重演R_i*,**、达标重演R_(?)*,**、高位重演R_(N)*,**三级,以重演性参数f(P)——连年及基本连年重演试点数(或重演面)表述之;并强调指出乃区试之核心。
The article holds that high yield, high yield rehearsal, adaptability and stability of the four varieties is the highest performance of the main production performance, should be used as the main regional variety selection test indicators, and should be unified with the appropriate parameters to be quantified to Make the summary assessment based on the scientific classification of the tested varieties. This paper suggests that the accuracy and completeness of high yield in the district test should be expressed in terms of the following three parameters: the (average) high yield level Yi / with reference to the reference cultivars and the significant difference in yield index I_Y *, ** / Adjacent to the significance of the significant difference between adjacent positions N *, **; for the identification of the regionalization of the key role of high yield rehearsal, it is recommended divided into different levels of reliability for the reproduction of R_i *, ** , Repeat the R_ (?) *, **, high repetition R_ (N) *, ** three levels, repeat the parameters f (P) And stressed that it is the core of the district test.
