| 摘 要： | 采用 Eberhart & Russell 模式及聚类分析方法,比较分析了14个冬小麦 F_1杂种和10个纯系(亲本)品种在5种不同地点籽粒产量的基因型×环境互作及其稳定性。结果表明,在基因型×环境互作的模式与性质上,杂交种和纯系品种均主要表现为非线性响应,但互作的程度杂交种明显小于纯系品种。杂交种的产量表现比纯系品种稳定。在产量响应上,纯系品种对有利环境条件的反应比杂交种更为敏感。回归分析和聚类分析法各有所长,综合运用,效果更好。 |
| 关 键 词： | 杂交小麦 产量 基因型与环境互作 模式分析 稳定性 |

| Abstract: | Regression and cluster analysis were applied to data obtained from a regional test of fourteen wheat(Triticum aestirum L.)hybrids and their ten parents/purelines over five locations to compare environmental responses and yield stabiliy of hybrid and pureline wheat cultivars across a range of environments.The results showed little different nature and patterns of genotype-environment(GE)interaction and significant non-linear responses for hybrids and purelines.The degree of GE-interaction for grain yield,how... |
| Keywords: | hybrid wheat yield genotype-environment interaction pattern analysis stability |
