用Francis和Kannenberg(1978)提出的平均数和变异系数分组法,对河南省14个不同大豆基因型联合区试中18个环境的资料进行了稳产性分组。并把14个基因型分为以下四类:(1)高产稳产类型(2)高产不稳产类型(3)低产稳产类型(4)低产不稳产类型。通过联合方差分析和显著性检验,发现周84—2和辐803产量显著地高于其余12个品种,二者本身没有显著差异,同属第一位。但周84—2稳产性不及辐803,特别适应区数也不及辐803多。周84—2在特别适应区种植,增产潜力有可能大于其它基因型。第一种类型中的其余4个基因型,都显著地比两个对照增产,稳产性也优于两个对照和84—2,可作为辐803和周84—2的搭配种使用。
Based on the average and variation coefficient grouping method proposed by Francis and Kannenberg (1978), the data of 18 environments in 14 different soybean genotypes in Henan Province were grouped according to their stability. And the 14 genotypes are divided into the following four categories: (1) high and stable yield type (2) high yield unstable type (3) low yield stable type (4) low yield unsteady type. Through the joint analysis of variance and significance test, it was found that the yields of Zhou 84-2 and Fen 803 were significantly higher than those of the remaining 12 cultivars. There was no significant difference between them, which belongs to the first place. However, the stability of the week 84-2 less than the spokes 803, in particular, the number of zones is less than 803 and spoke. Week 84-2 is planted in the special adaptation area, the yield potential may be greater than other genotypes. The other four genotypes in the first genotype were significantly more productive than the two controls and the stability was also better than the two controls and 84-2, which could be used as a crossover strain for Convox 803 and Week 84-2.
