“…Principal component analysis has been useful as a facilitating tool to discriminate genotypes in the analysis of many traits to estimate diversity in different crops, as can be seen in investigations to identify sources of resistance and quantification of secondary metabolites in response to anthracnose in peppers 31 ; to geographically discriminate uvaia genotypes 32 ; to characterize natural populations, germplasm accessions, and phytochemical components of mangaba 33 – 35 ; also to analyze recurrent selection efficiency in akebia populations 28 and the development of elite cultivars by ranking the variability of morpho-agronomic traits 25 , 36 .…”

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.

O Cerrado Brasileiro é um dos principais biomas do país, compreendendo vasta variedade de espécies vegetais, das quais, muitas delas, ainda são pouco exploradas cientificamente. Esta obra teve por objetivo explanar, de forma clara e concisa, as inúmeras possibilidades e aplicabilidades das árvores, plantas e/ou frutos do cerrado para utilização e agregação de valor a este bioma tão rico. Algumas das espécies que o leitor encontrará neste livro são Ipê, jabuticaba, algodãozinho, pequi, baru, cagaita e mirtilo, e assuntos como a interferência climática, utilização de madeira, diferentes biocompostos/fitoquímicos presentes nestes frutos, assim como a utilização dessas diversas espécies para desenvolvimento de novos produtos, quer seja de cunho alimentícios ou cosméticos, foram abordados. Agradecemos aos autores pelo empenho, disponibilidade e dedicação para o desenvolvimento e conclusão dessa obra. Esperamos, também, que esta obra sirva de instrumento didático-pedagógico para estudantes, professores dos diversos níveis de ensino em seus trabalhos e demais interessados pela temática.

This work was developed with the objective of characterizing the variability and genetic structure of matrices and progenies of the Mangaba genebank of Embrapa Tabuleiros Costeiros, to de ne a core collection. From the matrix of seven accessions, 289 individuals were generated, evaluated by nine SSR markers. The characterization of genetic variability was performed from the estimates: Average number of alleles observed (Na = 5.63) and effective (Ne = 2.71); Shannon Information Index (I = 1.04); Heterozygosity observed (Ho = 0.45) and expected (He = 0.51); Fixation index (f = 0.13); Percent polymorphism (%P = 90.47); and, Number of private alleles (Nap = 20). The Analysis of Molecular Variance (AMOVA) identi ed that the largest proportion of genetic variation is present within accessions (92%). The estimates of genetic differentiation (G ST and R ST ) were considered low (< 0.05) to moderate (0.05 to 0.15) magnitude. Multivariate analyses (PCoA, Rogers and Bayesian genetic diversity) did not discriminate the accessions according to origin. The formation of the core collection allowed retaining 94.90% of the identi ed alleles. The accessions present genetic variability to be explored in mangaba conservation and genetic improvement programs.
