13. Adaptability and stability of organic-grown arabica coffee production using the modified centroid method
Abstract This study aimed to identify promising arabica coffee genotypes for organic systems. The experiments were arranged in a randomized block design, with 30 genotypes and three replications. The adaptability and stability analysis was carried out using the modified centroid method, considering the mean yield of two biennia (2005/2006 and 2006/2007, 2007

14. Environmental stratification in cotton in the presence or absence of genotypes with high ecovalence
Abstract Cottonseed yield data of 17 genotypes, of which two genotypes contributed to more than 30% of the total ecovalence, and grown in 23 locations, were used to compare four methods of disjoint environmental stratification: a) environmental index (Ie): favorable or unfavorable environments; b) stratification in partitions that maximize the sum of squares

15. 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

16. Interação genótipos x ambientes dos teores de fibra e lignina em cana-de-açúcar / Genotypes x environments interaction in fiber and lignin content in sugar cane
As fibras vegetais possuem grande variação de acordo com o ambiente no qual se desenvolvem e usualmente são constituídas por aproximadamente 50% de celulose, 20% de lignina, 28% de hemicelulose e 2% de cinzas e outros compostos. Dentre estes, a lignina representa um dos principais entraves ao processo de hidrólise enzimática, pois dificulta o acesso da

17. Study of the interaction genotypes x environments in the selection process of upland rice.
The objectives of this study were the investigation of the interactions between upland rice lines/cultivars x planting system, years and locations. The experiments were conducted in the agricultural years of 2001/02 and 2002/03 in Lavras, Uberlandia and Patrocinio in the state of Minas Gerais (MG), Brazil, in two planting systems: conventional and no-tillage

18. 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
