The objective of this study was to assess genotype by environment interaction for area under disease progress curve values in spring barley grown in South-West Poland by the additive main effects and multiplicative interaction model. The study comprised of 25 spring barley genotypes (five cultivars: Basza, Blask, Antek, Skarb and Rubinek as well as all possible 10 two-way mixtures and 10 three-way mixtures combinations), evaluated at two locations in 4 years (eight environments) in a randomized complete block design, with four replicates. Area under disease progress curve (AUDPC) value of the tested genotypes ranged from 75.3 to 614.3, with an average of 175.3. In the AMMI analyses, 13.43% of the AUDPC value variation was explained by environment, 37.85% by differences between genotypes, and 18.20% by genotype by environment interaction. The mixture Basza/Skarb is recommended for further inclusion in the breeding program due to its low average AUDPC value (98.8) and is stable (AMMI stability value = 6.65).

使用加性主效应和乘性相互作用模型通过环境相互作用对春大麦疾病进展曲线下面积 (AUDPC) 值进行基因分型

本研究的目的是通过加性主效应和乘性相互作用模型评估波兰西南部春季大麦疾病进展曲线下面积值的环境相互作用的基因型。该研究包括 25 种春季大麦基因型（五种栽培品种：Basza、Blask、Antek、Skarb 和 Rubinek 以及所有可能的 10 种双向混合物和 10 种三向混合物组合），在 4 年内在两个地点（八个环境）进行了评估) 在随机完整区组设计中，有四个重复。受试基因型的疾病进展曲线下面积（AUDPC）值为75.3~614.3，平均值为175.3。在 AMMI 分析中，13.43% 的 AUDPC 值变异由环境解释，37.85% 由基因型之间的差异解释，18.20% 由基因型由环境相互作用解释。
