Evaluation of sugarcane genotypes and production environments in Paraná by GGE biplot and AMMI analysis

“…This value was higher than that reported by Guerra et al (2009) and by Verissimo et al (2012), who applied AMMI analysis to sugarcane, and similar to results of Chavanne et al (2007) and Silva et al (2012), who used GGE Biplot analysis for sugarcane and carrots, respectively.…”

“…Guerra et al (2009) and Verissimo et al (2012) identified genotypes and environments with same-sign PCI scores, with positive specific interactions for sugarcane. The classification of genotypes and environments established by Oliveira et al (2003) and Silva et al (2012) for soybean and carrot, respectively, was the same.…”

“…In turn, the more stable environments Astorga, Colorado and Goioerê had lower PCI1 scores ( Figure 2B). Guerra et al (2009) reported that environmental stability indicates the reliability of genotype ranking in a given test environment, in relation to the average ranking of the tested environments. Based on this definition, the greater stability of the locations Colorado, Goioerê and Astorga than of Bandeirantes and São Pedro do Ivai suggests that the genotype classification of the former group should have lower standard deviation of genotype performances than the classification in other production environments.…”

AMMI analysis to evaluate the adaptability and phenotypic stability of sugarcane genotypes

“…Among the most common methods are linear regression analysis, non-linear regression analysis, multivariate analysis and non-parametric statistics (Cornelius et al, 1996;Annicchiarico, 1997;Moreno-González et al, 2004). In recent years, the quantification of G × E interactions and yield stability studies involving sugarcane have been done through multivariate procedures, such as principal component analysis (Kumar et al, 2009;Guerra et al, 2009;Rea et al, 2011).…”

RB966928: Early maturing sugarcane cultivar

“…This phase was monitored over four growing seasons and the resistance/ tolerance to the most relevant diseases of sugarcane in the Central-Southern region was evaluated. For the release for planting, data from 45 samples were collected between the first cut (15 samples) and the fourth cut (five samples), which confirmed the beneficial qualities of the cultivar, especially its high ratoon yield and its elevated sucrose content, as well as its general adaptability and high stability of these traits (Guerra et al 2009). …”
