13. Analise da adaptabilidade atraves de regressao linear segmentada. 2. Aplicacao.
O metodo de regressao linear simples de Finlay & Wilkinson (1963), estendido por Eberhart & Russel (1966), postula uma relacao linear simples entre a resposta do genotipo e o indice de ambiente. Desta forma, ele nao e capaz de identificar o genotipo com sensibilidade de resposta ao ambiente desejavel, ou seja, o genotipo responsivo a embientes favoraveis ou

14. Components of variance and interaction between genotype and environment for annual girth increment in rubber tree.
To determine the nature and extent of genetical and environmental control of vigour through annual girth increment in rubber trees [Hevea brasiliensis (Willd.ex Adr. de Juss.) Muell.Arg.], seven clones were studied in a replicated trial in Sao Paulo State at four different locations. The clones represented a range of imported germplasm while the locations we

15. Epistasis and genotype-by-environment interaction of grain protein content in durum wheat
Parental, F1, F2, BC1 and BC2 generations of four crosses involving four cultivars of durum wheat (Triticum durum Desf.) were evaluated at two sites in Tunisia. A three-parameter model was found inadequate for all cases except crosses Chili x Cocorit 71 at site Sidi Thabet and Inrat 69 x Karim at both sites. In most cases a digenic epistatic model was suffic

16. Adaptabilidade e estabilidade de variedades de cana-de-açúcar em Alagoas e Pernambuco
The objective of this study was to assess the magnitude of the interaction between genotypes of cane sugar and environments and the adaptability and stability to the character of total sugar recovered (TSR) using the methodology proposed by Wricke (1965), Eberhart and Russell (1966), Cruz, Torres and Vencovsky (1989) and Annic-chiarico (1992). It was evaluat

17. Interação genótipo x ambiente via correlações genéticas entre rebanhos e normas de reação utilizando abordagem bayesiana em bovinos de corte / Genotype by environment interaction using genetic correlations between herds and reaction norms under bayesian approach in beef cattle
O presente estudo teve por objetivo estudar os efeitos da interação genótipo x ambiente sobre as características peso à desmama, peso ao sobreano e ganho de peso da desmama ao sobreano em bovinos da raça Nelore. Foram analisados 58.032 registros de peso à desmama ajustados para 205 dias (PD), 46.032 registros de peso ao sobreano ajustados para 550 dia

18. 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

19. Análises biométricas e mapeamento de QTLS para tolerância à seca em milho / Biometric analysis and mapping of QTLS for drought tolerance in maize
One of the major goals of crop improvement is the increase in agricultural productivity associated with the improvement for the consumption in human or animal feeding. These goals can be achieved through improvements in environmental conditions or by improving the genetic potential of populations. Recently, much has been discussed about global warming, clima

20. Uso dos mÃtodos AMMI e GGE biplot para anÃlises de adaptabilidade e estabilidade de hÃbridos de milho e estratificaÃÃo ambiental / The use of AMMI and GGE biplot methods for analysis of adaptability and stability of maize hybrids and environmental stratification
This work was carried out for evaluating stability, adaptability and environmental stratification, through the AMMI and GGE biplot methods by using maize hybrids trials data evaluation and for comparing the efficiency of these methods. Grain yield data originating from final trials of maize hybrids evaluation supplied by the Monsanto company were used and th

21. Imputação de dados em experimentos com interação genótipo por ambiente: uma aplicação a dados de algodão / Data imputation in trials with genotype by environment interaction: an application on cotton data
Os experimentos multiambientes são um tipo especial dos experimentos bifatoriais, muito usados em melhoramento genético de plantas, nos quais algumas cultivares são avaliadas em diferentes locais. Geralmente nesses estudos se encontra uma resposta diferencial das cultivares em cada local que é chamada de interação genótipo x ambiente ou G x E, que é

24. Partitioning genetic effects due to embryo, cytoplasm and maternal parent for oil content in oilseed rape (Brassica napus L.)
Analysis of genetic main effects and genotype x environment (GE) interaction effects on the oil content of oilseed rape (Brassica napus L.) was conducted by using a genetic model for the quantitative traits of seeds in diploid plants. The experiments were carried out over two years with 8 parents and a diallel mating design, which produced F1 and F2 generati
