Última Productivity and quality of Formosa and Solo papaya over two harvest seasons PAB Barros,Fabíola Lacerda de Souza; Kuhlcamp,Karin Tesch; Arantes,Sara Dousseau; Moreira,Sarah Ola. Abstract: The objective of this work was to evaluate the productivity and quality of papaya fruits (Carica papaya) of the Solo (12 genotypes) and Formosa (9 genotypes) heterotic groups over two harvest seasons. The experiment was conducted under field conditions in the municipality of Pinheiros, in the state of Espírito Santo, Brazil, in a randomized complete block design. Ten morpho-agronomic and physicochemical variables of the fruits were measured in winter (210-300 days after planting) and summer (450-540 days after planting). The data were subjected to the combined analysis of variance, to the breakdown of the genotype x environment interactions, and to the grouping of means by the Scott-Knott test. Although harvest season affected the evaluated... Tipo: Info:eu-repo/semantics/article Palavras-chave: Carica papaya; Agronomic performance; Environmental effect; Genotype evaluation.

Moreira,Sarah Ola; Kuhlcamp,Karin Tesch; Barros,Fabíola Lacerda de Souza; Zucoloto,Moises; Moitinho,Alyce Carla Rodrigues. Abstract Few cultivars of papaya from the Formosa group are available to producers, and the development of new genotypes is indispensable. Thus, the use of effective selection strategies to obtain more productive cultivars and better quality fruits is also necessary. The aim of this study was to select of half-sib families (HSF) of papaya using the methodology of mixed models. Nineteen HSFs from the Incaper’s papaya breeding program were evaluated in a randomized block design with five replicates and nine plants per plot. The selection was made based on fruit mass (FM), pulp thickness (PT), soluble solids content in pulp (SS) and number of fruits (NF). The genetic parameters and genotypic values were estimated by the REML/BLUP procedure. The selected HSFs...

Frutic. Moreira,Sarah Ola; Kuhlcamp,Karin Tesch; Barros,Fabíola Lacerda de Souza; Zucoloto,Moises; Godinho,Tiago de Oliveira. Abstract Selection of superior genotypes based on the simultaneous responses to different characteristics is a fundamental strategy in plant breeding. This study aimed to compare the efficiency of four selection index constructed using phenotypic and genotypic values in a segregating population of the cultivar Rubi Incaper 511. Eight morpho-agronomic variates and the severity of black-spot and phoma-spot were evaluated under field conditions. The classical selection index were calculated based on non-standardized phenotypic means (NSM), standardized means (SM), and genotypic values predicted by REML/BLUP (GVP), using predetermined economic weights. Additionally, the rank sum (RS) was obtained on the basis of the classification of individuals in these...

Frutic. Moreira,Sarah Ola; Kuhlcamp,Karin Tesch; Barros,Fabíola Lacerda de Souza; Oliveira,Sabrina Batista de; Trindade,Roberto dos Santos. Abstract Correlations and path analysis allow the understanding of the interrelations between characteristics of interest to the plant breeding. However, in order for their results to be reliable, the undesirable effect of multicollinearity must be excluded. The objective of this study was to estimate the correlations and their partitioning in direct and indirect effects, by path analysis, on the fruit production per plant (FP) of papaya from the heterotic Solo and Formosa groups, using two different strategies to circumvent multicollinearity. Eleven agronomic variables were evaluated in twelve papaya genotypes from the Solo group and nine from the Formosa group. Path analysis was obtained with the FP as the basic variable and to eliminate...
