1. Adaptability and stability of maize genotypes in growing regions of central Brazil
ABSTRACT This study aimed to estimate and compare parameters of adaptability and stability for maize grain yield in a variety of environments by different projection methods. Data from experiments on 36 maize genotypes, in simple lattice 6x6, in 2012/13 season performed at nine growing locations in central Brazil were used. Adaptability and stability analyse

2. The usefulness of GGE biplot methodology for line × tester data of maize inbred lines
ABSTRACT The genotype + genotype × environment (GGE) biplot methodology has the potential to determine combining ability effects, identify efficient testers, and distinct heterotic groups in a line × tester study. However, it has not been adequately applied for such analysis. Therefore, this study was done to assess the combining ability of some maize inbr

3. Simultaneous selection for yield, adaptability, and genotypic stability in immature cowpea using REML/BLUP
Resumo: O objetivo deste trabalho foi selecionar genótipos de feijão-caupi simultaneamente para alta produção de grãos imaturos, adaptabilidade e estabilidade genotípica, ao se considerar interações genótipos x ambientes. Foram utilizados os modelos mistos máxima verossimilhança restrita (REML)/melhor predição linear não viciada (BLUP). Avaliar

4. Genotype x environment interaction analysis of multi-environment wheat trials in India using AMMI and GGE biplot models
Abstract Fifty wheat genotypes were evaluated at nine diverse locations in India to identify high-yielding and stable genotypes. The analysis of variance based on additive main effects and multiplicative interaction (AMMI) indicated significant genotype, environment and genotype - environment (GE) interactions, with a total variation of 5.99, 20.23 and 73.77

5. Phenotypic stability in cassava estimated by the AMMI analysis with supplementary genotypes
Abstract Adaptability is the yield response of cassava genotypes to environmental improvement, and stability is the predictability of this response to variations. The objective of this study was to evaluate the yield stability and adaptability of cassava varieties and clones using the AMMI (Additive Main Effects and Multiplicative Interaction) methodology an

6. Potencial de linhagens de feijão com relação aos teores de proteína e minerais nas sementes
Este trabalho foi realizado com os objetivos de quantificar os teores de proteína e minerais de linhagens de feijão comum pertencentes ao Banco de Germoplasma da Universidade Federal de Lavras (UFLA), verificar se existe relação entre a cor da semente e o teor de proteína e minerais, verificar se os teores de zinco e ferro são afetados pela safra de cu

7. Multivariate analyses of genotype x environment interaction of popcorn.
The objectives of this work were to evaluate the genotype x environment (GxE) interaction for popcorn and to compare two multivariate analyses methods. Nine popcorn cultivars were sown on four dates one month apart during each of the agricultural years 1998/1999 and 1999/2000. The experiments were carried out using randomized block designs, with four replica

8. 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

9. Genetical and environmental analyses of yield in six biparental soybean crosses.
The yearly genetic progress obtained by breeding for increased soybean yield has been considered acceptable worldwide. It is common sense, however, that this progress can be improved further if refined breeding techniques, developed from the knowledge of the genetic mechanisms controlling soybean yield, are used. In this paper, data from four cultivars and/o
