“…According to Miranda et al. (2021), some of the 62 hybrids of the present work showed superiority in relation to the main commercialized cultivars, such as “Golden,” “Tainung 01,” and “Aliança,” where some hybrids were considered promising for launching as new cultivars with a focus on the market, with high firmness and SSC.…”

“…Some hybrids such as "UC 14" and "UC 16" developed by UENF/CALIMAN (the same breeding program to which this work belongs) have already been released and offer a great alternative for replacing existing cultivars, such as "Golden" and "Tainung 01" (Da Luz et al, 2015;Pereira et al, 2019). According to Miranda et al (2021), some of the 62 hybrids of the present work showed superiority in relation to the main commercialized cultivars, such as "Golden," "Tainung 01," and "Aliança," where some hybrids were considered promising for launching as new cultivars with a focus on the market, with high firmness and SSC.…”

“…(2009) reported that the hermaphrodite papaya tree is cleistogamous, and its preferred mode of reproduction is through facultative self‐pollination. Thus, papaya breeding programs have sought to explore heterotic effects in obtaining hybrids via diallel or topcross designs (Miranda et al., 2021; Santa‐Catarina et al., 2019; Vettorazzi et al., 2021; Vivas et al., 2011; Vivas et al., 2013) and the exploration of inbreeding via generation advancement (Cortes et al., 2019; Santana et al., 2021). Consequently, the main papaya breeding program in Brazil, UENF/Caliman, has been looking for ways to provide superior genotypes that have a high fruit yield, disease resistance, and fruits with high firmness and soluble solids content (SSC) for genotypes of the Solo and Formosa group and intermediate cultivars to both groups (Pereira et al., 2019).…”

The knowledge of the associations between the variables and the cause‐effect discrimination allows the breeders to make efficient of new cultivars development with traits that meet of producers and consumers demands. Therefore, the present work aimed to study the associations and among the quality variables of papaya (Carica papaya L.) fruits and the effects in selection process. Eight variables related to fruit quality were evaluated in 62 topcross hybrids. The phenotypic and genotypic correlations and path analyses, were performed to verify the associations between the variables and the effects on pulp volume. Canonical correlation analysis between primary and secondary quality variables was also carried out. Fruit firmness (FF) and soluble solids content showed a positive and significant genotypic correlation, providing evidence for selecting fruits with high averages for both variables. Fruit weight and pulp thickness (PT) were the variables that most contributed to the reduction and increased pulp volume percentage (%PV), respectively. The canonical correlation analysis showed an increase in PT associated with an increase in the fruit length and %PV variables. The physical‐chemical variables showed a low association with others, which will make the selection process more laborious to obtain satisfactory gains between the groups of variables.This article is protected by copyright.

Acerola is a tropical superfruit known for its rich vitamin C content. Due to the considerable genotypic variability in fruit quality traits, an effective multitrait selection is essential for an acerola breeding program aimed to identify promising genotypes for distinct purposes. In this study, fruits from 95 acerola genotypes were evaluated at two maturity stages across three growing seasons. The genotypes were selected for vitamin C extraction (green unripe fruits) and fresh consumption (red ripe fruits), using four selection indices. The variability ranges for quality traits were as follows: fruit mass of 4.19–5.60 g (green fruit) and 4.13–5.90 g (red fruit), vitamin C of 1492.0–2995.8 mg/100 g (green fruit) and 1247.2–2873.6 mg/100 g (red fruit); soluble solids and titratable acidity of 4.70–13.07% and 0.60–1.60%, both in red fruit. Desirable gains for all traits were achieved by the multitrait indices. Twelve genotypes (Flor Branca, IARP 01, ALHA 03, ACO 10, Junko, Natália, LAG 04, Lígia, Luisa, LAG 05, Costa Rica and BV 01) stood out for vitamin C extraction at the green stage, as well as eleven genotypes (Manoela, IARP 01, Okinawa, LAG 04, Costa Rica, Clone 71/2, ACO 05, ACO 14, LAG 01, BRS Rubra and MAR 10) excelled for fresh consumption at the red stage. Costa Rica, IARP 01 and LAG 04 were selected as dual-purpose genotypes, intended for both fresh consumption and vitamin C extraction.

“…It is also noteworthy that the biochemical traits, such as the soluble solids content, are decisive in consumer acceptance for in natura consumption and in the production of industrialized products. For these reasons, the new cultivars must present high quality fruits to be marketed, transported and consumed 14 .…”

Despite the relevance of the global scenario regarding the papaya (Carica papaya L.) trade, there is still a limited number of papaya cultivars with different fruit patterns. Therefore, it is essential to explore the genetic variability at all levels of the germplasm used in the development of new papaya cultivars to meet its marketing goal. Thus, this study measured and explored the potential of genetic variability based on related to fruit quality traits, of a population of papaya lines in the F5 generation through several statistical analyzes. For this, 97 inbred lines obtained using the Single Seed Descent method, resulting from a cross between the JS-12 and Sekati genotypes, both with Formosa fruit pattern, were evaluated. Results indicated there was genetic variability in the fruit quality. The traits that most contributed to the variability were related to the fruit shape. The diverse population of 97 inbred papaya lines in the F5 generation showed promise for producing commercial-sized fruits in Formosa, Intermediate, and Solo patterns. Additionally, the selection of inbred papaya lines based on fruit shape using morpho-anatomical traits does not compromise physical and chemical parameters related to fruit quality.
