应用AMMI模型分析烤烟区试品种稳定性

Analysis on the Stability of Flue-cured Tobacco Varieties in Regional Trail by AMMI Model

AMMI模型在分析基因型与环境互作效应方面有明显的优势,可定量地描述各品种稳定性差异以及各地点对品种鉴别力的大小。为筛选适应河南省特定生态条件下的优良烤烟新品种,应用AMMI模型对2010年河南省烤烟区域试验4个试点7个参试品种的丰产性及稳产性进行分析。结果表明,所有参试新品种产量均值均高于对照NC89,其中,Y106和H8190具有丰产稳产的特性,Y102产量最高,但稳定性较差;8182丰产性差,稳定性好;8122丰产性较差,稳定性较差;‘优选一号’丰产性差,稳定性较好;对照NC89丰产性差,稳定性一般。

AMMI model has obvious advantages of analyzing the interactions between varieties and locations, and it can describe the differences in the stability of varieties and the discriminability of varieties in different locations quantitatively. In order to select quality flue-cured tobacco varieties which adapted specific ecological conditions in Henan, the prolificacy and yielding stability of 4 pilots and 7 varieties were analyzed for flue-cured tobacco regional trial in Henan Province with AMMI model. The results showed that all the mean yield of new varieties tested was higher than control NC89. The variety Y106 and H8190 had high and stable yield with wide adaptability. Y102 had highest yield, but it had a poor stability. The yielding dependability of variety 8182 was better, but it had a poor prolificacy. The variety 8122 and ‘ Youxuanyihao ’ had poor prolificacy and yielding dependability. The prolificacy of variety NC89 was poor, and it had a general yield stability.
