通过河南省1984年小麦品种联合区试21点的产量资料,分析了品种,地点和品种×地点的互作效应,分别找出了八个基因型的特别适应区。通过特别适应区中平均产量比较,八种基因型可分为三类:(1)450公斤/亩以上的有偃师9号和洛阳7602。偃师9号是一个高产、稳产及特别适应区较多的品种,能在多种生态类型区发挥出最大生产潜力;(2)425公斤/亩以上的有百农79—2和80—B_2,两者生产能力相同,但80—B_2比百农79—2的特别适应区多,稳产性不但比百农79—2好,而且比所有参试品种都好;(3)其余四种基因型的产量低于425公斤/亩,不作进一步比较。
Based on the yield data of Henan Province 1984 wheat variety trial zone at 21 o’clock, the interaction effects of variety, location and variety × locality were analyzed, and the special adaptation zones of eight genotypes were identified respectively. The eight genotypes can be divided into three categories by comparing the average yield in the special zones: (1) Yanshi No. 9 and Luoyang 7602 with a density of more than 450 kg / mu. Yanshi 9 is a high-yielding, stable-yielding and special-adapted area with more productive potential and can exert its maximum production potential in a variety of ecotype areas. (2) There are 100-Nongong 79-2 and 80-B_2 , Both of them had the same production capacity. However, the 80-B 2 had more special adaptation zones than that of Baiyong 79-2, and the stability was not only better than that of Baiyong 79-2, but also better than that of all tested varieties. (3) The other four genes Type yields below 425 kg / acre, without further comparison.
