Correlações fenotípicas e análise de trilha em caracteres morfoagronômicos de mamoeiro

Abstract: A estimativa da correlação entre caracteres é de extrema importância para o melhoramento, pois mede o grau de associação entre características e possibilita avaliar o quanto a alteração em um caráter pode afetar os demais. Entretanto, a quantificação e interpretação da magnitude desta não permite o desdobramento das correlações simples nos seus efeitos diretos e indiretos. Objetivou-se com este trabalho obter estimativas de correlações fenotípicas, genotípicas e análise de trilha entre características morfoagr… Show more

“…Therefore, it is necessary to develop new papaya cultivars, ensuring their sustainability (OLIVEIRA et al, 2010;SILVA et al, 2016). The search for new genotypes is facilitated when the relationships between characters used in selection are known, especially when the variable of interest is polygenic, has its phenotype expressed late or of medium or low heritability, such as fruit production.…”

“…For papaya, studies that seek to understand the correlations and their direct and indirect effects through path analysis for the production, number and mass of fruits are available in the literature (OLIVEIRA et al, 2010;SILVA et al, 2016). However, these analyzes do not consider the different heterotic groups of papaya, divided in Solo and Formosa, that have phenotypic patterns, such as size and fruit mass and different plant architecture.…”

“…The development of plants with larger fruits is a primordial property in breeding of these fruit species. However, this quantitative trait is controlled by a high number of genes, strongly influenced by the environment and resulting from multiplicative effects of other essential traits (FERREIRA et al, 2016). Faced with the challenge of meeting these requirements, competence is required to identify the best genotypes in the breeding programs.…”

“…Knowledge about the phenotypic correlations is important when a simultaneous selection of traits is desired as well as in cases of low heritability and/ or difficulty of evaluation of the target trait (SILVA et al, 2016). Moreover, when relations between traits of complex nature are analyzed, e.g., fruit weight and its components, information about the direct and indirect effects of each trait on the basic trait (fruit weight) is required.…”

“…Isso denota que tal valor de correlação foi originado pelo fator de causa direta, participando com 96,91% desse número, podendo o restante ser atribuído aos efeitos indiretos. Silva et al (2016) recomendaram que resultados com está natureza, realiza-se a seleção truncada, facilitando a obtenção de plantas mais produtivas.…”
