Análise da adaptabilidade e da estabilidade de genótipos de trigo como ferramenta auxiliar na recomendação de novas cultivares

Abstract: A análise da adaptabilidade e da estabilidade de genótipos de trigo auxilia o melhorista na recomendação de novas cultivares, indicando linhagens de adaptação ampla ou específica aos ambientes. Esse procedimento é particularmente importante para a cultura do trigo, principalmente levando em consideração a grande diversidade de ambientes a que o cereal é submetido no Brasil. Assim, este trabalho teve como objetivo identificar genótipos de trigo com ampla adaptação e estáveis para recomendação. Os dados para as … Show more

“…The highest average grain yield was in VCU Region 1 (compared to Regions 2 and 3), likely due to the fact that this region has a higher average altitude, which is related to a higher photothermal quotient (PQ) that enables a longer phenophases and greater differentiation in the tillers and flower primordial (Fischer 1985, Magrin et al 1993, Cunha et al 2005.The high average grain yield in VCU Region 1 was due to the adoption of more intensive management practice related to the use of irrigation. Differences in wheat yield potential between the VCU regions have also been observed by other authors (Caierão et al 2006, Cargnin et al 2006, Franceschi et al 2010, Silva et al 2011). …”

“…Some models for analysis of adaptability and stability allow breeder to perceive the behavior of each genotype in favorable and unfavorable environments. They provide breeders necessary information to select the best genotype for each environment or a genotype that is proper in both environments (Biudes et al, 2009;Caierão et al, 2006;Silva et al, 2011).…”
