13. Factor analysis applied to the G+GE matrix via REML/BLUP for multi-environment data
Abstract The genotype x environment interaction is frequently observed in many crops and studies on environmental stratification and genotype adaptability have been proposed to understand it. The aim of this study was to carry out factor analysis in data from multi-environment experiments by the mixed model approach (REML/BLUP). Instead of adjusted phenotypi

14. Analyzing genotype-by-environment interaction using curvilinear regression
In the context of multi-environment trials, where a series of experiments is conducted across different environmental conditions, the analysis of the structure of genotype-by-environment interaction is an important topic. This paper presents a generalization of the joint regression analysis for the cases where the response (e.g. yield) is not linear across e

15. Cooking time of black beans genotypes evaluated in different environments.
Lines developed by breeding programs are expected to have improved agronomical characteristics, good culinary quality such as environment affected cooking time. Since the final quality tests of black bean lines from the Rice and Beans Research Center breeding program are carried out in a great number of environments. it is possible to determine the cooking t

16. Environmental stratification in Paraná and Santa Catarina to evaluate common bean genotypes.
The purpose of this study was the environmental stratification of the states of Paraná and Santa Catarina for the evaluation of carioca common bean genotypes. The grain yield was evaluated in 20 trials, in a randomized block design with three replications testing 16 genotypes with carioca grain. The environments were stratified by five methodologies: tradit

21. Nonparametric stability methods for interpreting genotype by environment interaction of bread wheat genotypes (Triticum aestivum L.)
Evaluation of performance stability and high yield is essential for yield trials conducted in different environments. We determined the stability of 10 bread wheat (Triticum aestivum L.) genotypes (5 cultivars and 5 advanced lines) using nonparametric stability measures and compared nonparametric stability statistics across 19 environments in the Central Ana

24. Adaptability and stability of 20 soybean genotypes for the macro-region 3 / Adaptabilidade e estabilidade de 20 genótipos de soja para a macroregião sojícola 3
This study evaluated the adaptability and stability of 20 soybean genotypes, where 10 of them were lines of the breeding program of Monsoy Ltd. and the other 10 were commercially used controls. The experiments were done in the agricultural years 2005/2006 and 2006/2007, in the soybean macro-region 3 (micro-regions 301, 302 and 303). The experimental design w
