摘要
本试验系统研究了不同用途的优质小麦品种(系)在不同生态条件下的产量变化情况,并对其稳定性进行了分析。结果表明:经方差分析,试点间差异达极显著水平,品种与试点互作效应达显著水平;产量稳定性分析表现,PH1521、优麦3号、济麦20和淄麦12的Shukla变异系数较小,为稳定性高的品种,能适应较特殊的环境;济麦20和淄麦12的产量和稳定性均较好,可在较大范围内获得较高产量。
Yield changes and stability of different genotype wheats in different regions were analysized. It showed that difference were significant among regions. The interaction of varieties and environment was marked. The Shukla C.V. of PH1521,Youmai 3,Jimai20 and Zimai 12 were relatively smaller. Those varieties were more stable and can adapt to specific environments. Yield of Jimai20 and Zimai 12 were more stable, and can get a desirable yield in different parts of Shandong province.
