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. Selection of maize top-crosses for different nitrogen levels through specific combining ability
ABSTRACT An alternative to increase yield without raising the production costs and minimizing the dependence of agricultural inputs is the development of maize genotypes presenting high nitrogen (N) use efficiency under low N level conditions. Thus, the objective of this study was to estimate the specific combining ability of maize top-crosses under high and

3. 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

4. Key locations for soybean genotype assessment in Central Brazil.
The objective of this work was to identify key locations for the establishment of soybean (Glycine max) genetic breeding programs, in the Central Region of Brazil. Grain yield data of three maturity groups of soybean genotypes, from regional trials conducted over three years, at 18 locations in Brazilian Cerrado were used. A key location for the early pha

5. Avaliação agronômica morfológica e molecular de progênies de policruzamento de trevo branco (Trifolium repens L.) em dois locais do Rio Grande do Sul / Agronomic, morphological e molecular evaluation of white clover (Trifolium repens L.) polycrosses progeny in two places of Rio Grande do Sul
White clover is a legume forage most widely used in pastures during the winter and spring in the RS, but nevertheless may have persistence problems, especially in summer. The aim of this work was to select higher forage yield and tolerance to low water availability genotypes, evaluating agronomically their progeny and characterizing them morphologically and

6. Seleção e análise dos modelos PARAFAC e Tucker e gráfico triplot com aplicação em interação tripla / Selection and analysis of the PARAFAC and Tucker models and triplot graphic with application in triple interaction
The present work has the following objectives: to propose a systematics for the study and the interpretation of the phenotypic stability and adaptability, through several multiway models (PARAFAC and Tucker3); to propose a graphic, called of Triplot, that it makes possible to evaluate the relations between the 3 ways (genotypes, locations and years); to impl

7. Efeito da competição dentro de parcelas, da interação genótipos x ambientes e influência de estratégias de seleção no melhoramento genético de eucalipto / Effect of competition within plots, of the genotype x environment interaction and influence of selection strategies in genetic breeding of Eucalypt
The aim was to determine the genetic parameters of progeny tests in Eucalyptus grandis Hill Maiden with 3 years old under competicional effect, as well as to study the genotype x environment interaction and its impact on strategies for direct and indirect selection and analyze different selection strategies like selection among and within, mass, stratified m

8. Genotypes by locations interaction in sugarcane and perspectives of environmental stratification / Interação genótipos x locais em cana-de-açúcar e perspectivas de estratificação ambiental
This study was performed on the basis of experimental results concerning RB genotypes belonging to Series 92 of the sugarcane breeding program of the Universidade Federal de São Carlos (PMGCA - UFSCar), having as purpose to evaluate representativeness of the locations that compose its experimental net. This way, the characters tons of cane per hectare (TCH)

9. 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

10. Epistasia e interação epistasia por locais para a produção de grãos em soja / Epistasis and epistasis by location interaction for grain yield in soybean
In soybean breeding programs the selfing progenies are generally evaluated as possible cultivars. The study of the structure of the genetic variation among progenies in different generations of selfing depends upon the action of the loci involved and the variability of the trait under study. In soybeans, grain yield is the most important trait and it is char

11. Agressividade de isolados de Cercospora zeae-maydis em genótipos de milho / Aggressiveness of Cercospora zeae-maydis isolates in maize genotypes
Maize (Zea maydis L.) is of great social, cultural and economical importance in Brazil and in the world. Maize diseases are the main factors that reduce crop yield. Gray leaf spot, caused by the fungus Cercospora zeae-maydis Tehon &Daniels, is one of the most important diseases in many countries. Given that the disease can be controlled by the use of resista

12. Environmental stratification for evaluation cotton genotypes in Mato Grosso State, Brazil. / Estratificação ambiental para avaliação de genótipos de algodoeiro no estado de Mato Grosso.
Data of yield were obtained from Regional Yield Trials of cotton (Gossypium hirsutum) genotypes carried out in Mato Grosso State, Brazil in 1998/99, 1999/00 and 2000/01, was used in this study on environmental stratification and evaluation of the minimum number of environments required for cotton genotypes assessments. Eight genotypes were evaluated in 1998/
