- Abstract
In assessing the performance of different varieties both the production potential and its stability should be taken into account. High yield stability usually refers to a genotype ability to perform consistently, whether at high or low yield levels across a wide range of environments. An ideal variety should have a high mean yield combined with a low degree of fluctuation under different environments. The objectives of this study were to evaluate the stability of fruit weight for different cultivars and landraces of paprika pepper through different statistical models to analyze and partitioning the genotype-environment interaction. Landraces Cenad, Mocirla, Cermei, Belint achieved values of fruit weight superior to experimental mean with a high stability. In the same time for genotypes Seleuş, Cutina, Csardas, Arad 6 high stability was associated with levels of this trait inferior to the experimental mean. Based on vector length, we observed that cultivars Szeged and Karmina achieve a fruit weight inferior to the experimental mean highly influenced by genotype x environment interaction, while the superior value of cultivars Carmen and Kalacsai was due to the influence of genotype x environment interaction. According to all results a high stability associated with low influence of the genotype x environment interaction over the phenotypic expression of fruit weight was observed in landraces: Buzad, Pocola, Craiva, Cutina.
