应用GGE双标图对不同基因型谷子农艺性状及产量稳定性分析

Analysis of Agronomic Characters and the Yield Stabilities of Different Genotype Millets with GGE Biplot

通过GGE双标图分析了7种不同基因型的谷子品种在晋中生态条件下的产量与性状差异以及各品种的突出优势表现,为筛选该地区适宜品种以及根据所需培育适宜品种提供依据。结果表明,张杂谷系列表现出较大的杂种优势,尤其以张杂3号的籽粒产量最高,常规谷种以tg的分蘖力较强,产量高于晋谷。谷粒籽粒的产量与有效穗数、单穗粒重和千粒重呈显著的正相关关系,与穗数、有效穗数、分蘖数和单穗粒重呈负相关关系。

The GGE double plot analysis was used to evaluate the production,the different characteristic and the outstanding properties of seven different genetic types of foxtail millet in jinzhong ecological conditions in order to screen the area suitable varieties and provide the reference for future cultivating.The results showed that the Zhangza series possessed great heterosis in which the highest yield was from the Zhangza 3.The TG,one of traditional cultivars displayed higher tillering ability,and its production ability was higher than Jingu.The significantly positive correlation was observed between the production and the effective ear numbers,single grain weight and the thousand seed weight,and the significantly negative correlation was exhibited between the effective panicles,tiller numbers and single grain weight.
