“…Usually, cambuci fruits present the following values of other physical and chemical properties: moisture content 86-90%, pH 2-3, fibers 0.1-0.2%, total lipids 0.02-0.05%, proteins 0.02-0.03%, carbohydrate 0.9 g Kg-1, ash content 0.02%, and mineral profile comprising nitrogen 0.01-0.03, phosphorus 0.01, potassium 0.1, calcium 0.001-0.005, magnesium 0.01, sulfur 0.01, boron 0.1, zinc 0.1, iron 0.2-0.3, manganese 0.02-0.1, copper 0.02-0.04, sodium 0.3-0.6 g kg −1 DW [3,5,20]. These parameters were previously reported presenting genetic variability values for fruit characters once, when different accessions were evaluated, the coefficient of variance was demonstrated as high levels (>20%), as Bianchini et al show [21]. However, there is no report of the complete metabolite profile as a parameter of chemical changes to the point the variability genetic of cambuci fruits as describe in the next section.…”

The cambuci is a native Brazilian fruit from the Atlantic Forest biome. A soft and astringent pulp, a green color, and a sweet aroma are its main characteristics. Classical food quality attributes (fresh fruit mass, fruit height, diameters, total soluble solid, titratable acidity, and ratio) and the metabolic profile from ten accessions from three different locations were analyzed herein by analytical methods (refractometry and neutralization titration) and nuclear magnetic resonance spectroscopy. Concerning sugar content, sucrose was the predominant compound, with glucose and fructose alternating in second, depending on the accession. Citric acid was the most relevant acid, followed by shikimic and quinic acids in quite variable amounts. These three main acids vary in amounts for each accession. Ascorbic acid content emerges as an important quality attribute and makes this fruit nutritionally attractive, due to values comparable to those contained in citric fruits. The main amino acids identified in cambuci were glutamic acid individually or in comprising the tripeptide glutathione (glutamic acid, cysteine, glycine). The quality diversity of the evaluated accessions suggests the potentiality of cambuci use in future breeding programs.

“…Phenotypes that gathered negative values of PC1 and PC2 were characterized by the combination of high polyphenols and vitamin C content. Cruz et al (2004) suggested performing crosses between parent accessions with the greatest possible divergence and good performance to increase heterosis and the chance of generating superior individuals; in fact, crosses between divergent phenotypes allows the heterotic effect to be exploited and segregating populations with greater variability in crosses to be obtained (Oliveira et al 2009;Bianchi et al 2017). From the industrial point of view, acerola fruits from cluster 2 were the most interesting for their biochemical constituents, even if they had low average fruit size values (Fig.…”

Acerola fruit is one of the richest natural sources of ascorbic acid ever known. As a consequence, acerola fruit and its products are demanded worldwide for the production of health supplements and for the development of functional products. Acerola phenotypes (103) were selected from Western Paraná State and evaluated to obtain information on fruit quality characteristics with the aim of using them in genetic breeding programs for improving acerola in the subtropical region of Brazil. Multivariate analysis of the dissimilarity among the phenotypes was performed using the heat map clustering method and principal component analysis. Results obtained using the two methods were comparable, and the methods were effective in discriminating between samples and variables. This indicates variability among phenotypes with potential for its use in breeding programs. Based on the mean values of the chemical and physical characteristics of fruits and considering the differences among the phenotypes, nine crosses are suggested to generate a future improved population, namely between phenotype numbers 37, 4, 14, 29 and phenotype numbers 99, 60 and 66, belonging to the two different clusters and characterized by high vitamin C content and yield or higher values of fruit size and color parameters.

“…The characterization of genotypes used in breeding programs provides useful information to understand and take advantage of their diversity (Cerqueira- Silva et al 2014). Studies on this genetic diversity provide basic information about parents, joining genotypes in heterotic groups and obtaining segregating populations with a greater variability in crossings (Bianchi et al 2017). Thus, this study aimed to verify the direct and indirect effects of traits via path analysis on grain yield, as well as to quantify the genetic divergence among wheat cultivars grown under heat-stress conditions.…”

One of the biggest limitations for the wheat crop expansion to Brazilian tropical regions is the high temperature in the rainy season. This study aimed to select, based on genetic divergence and path analysis, cultivars that tolerate cultivation in the summer (heat stress). Nine wheat cultivars were sown, using a randomized block design with three replications, with plots consisting of 10 rows of 6 m and row spacing of 0.15 m. The highest grain yield and number of ears m-2 were observed for the CD 150 cultivar and the largest 1,000-grain weight for CD 116. BRS 220, IPR 136, IPR 144 and BRS Pardela had the highest number of sterile spikelets. The highest number of grains per ear was observed for CD 150, CD 116, BRS Pardela, IPR 130 and IPR 85, showing direct effects on grain yield, evidenced by the path analysis. CD 116 and CD 150 were the most productive cultivars and can be considered as possible parents in wheat breeding programs. IPR 85, CD 116, CD 108 and CD 150 showed a greater tolerance to high temperatures.
