Abstract

This study analyzed the genotype x environment interaction (GE) for the juice productivity (JuProd) of 12 yellow passion fruit varieties (Passiflora edulis Sims. f. flavicarpa Deg.) using additive main effects and multiplicative interaction (AMMI) model and auxiliary parameters. The experiments were conducted in eight environments of Bahia State, Brazil, using a randomized block design with three replications. Analysis of variance showed significant effects (P ≤ 0.01) for environments, genotypes, and GE interaction. The first two interaction principal component axes (IPCAs) explained 81.00% of the sum of squares of the GE interaction. The AMMI1 and AMMI2 models showed that varieties 09 and 11 were the most stable. Other parameters, namely, the AMMI stability value (ASV), yield stability (YSI), sustainability, and stability index (StI), indicated that other varieties were more stable. These varying results were certainly a consequence of methodological differences. In contrast, the ranking of varieties for each of the stability parameters showed significant positive correlations (P ≤ 0.05) between IPCA1 x (ASV, YSI), JuProd x (StI, YSI), YSI x ASV, and StI x YSI. Cluster analysis based on the genotypic profile of the effects of the GE interaction identified three groups that correlated with the distribution of varieties in the AMMI1 biplot. However, the classification of stable genotypes was limited because the association with the productivity was not included in the analysis. Variety 08 showed the most stable and productive behavior, ranking above average in half of the environments, and it should be recommended for use.

摘要

本研究使用加性主效应和乘积交互作用(AMMI)模型及辅助参数,分析了12个黄色西番莲品种(西番莲西姆斯变种黄果西番莲)果汁产量(JuProd)的基因型×环境互作(GE)。试验在巴西巴伊亚州的8个环境中进行,采用随机区组设计,重复3次。方差分析表明环境、基因型和GE互作具有显著效应(P≤0.01)。前两个互作主成分轴(IPCA)解释了GE互作平方和的81.00%。AMMI1和AMMI2模型表明09号和11号品种最稳定。其他参数,即AMMI稳定性值(ASV)、产量稳定性(YSI)、可持续性和稳定性指数(StI)表明其他品种更稳定。这些不同的结果肯定是方法差异的结果。相比之下,每个稳定性参数的品种排名显示IPCA1×(ASV、YSI)、JuProd×(StI、YSI)、YSI×ASV和StI×YSI之间存在显著正相关(P≤0.05)。基于GE互作效应的基因型概况进行的聚类分析确定了与AMMI1双标图中品种分布相关的三组。然而,稳定基因型的分类受到限制,因为分析中未包括与生产力的关联。08号品种表现出最稳定和高产的特性,在一半的环境中排名高于平均水平,应推荐使用。
