Principal Component and Biplot Analysis in the Agro-industrial Characteristics of Anacardium spp.

Abstract

The cajuí Anacardium spp., which is similar to the caju Anacardium Ocidentale L., is a species adapted to edaphic-climatic conditions of the biome Cerratinga (Cerrado e Caatinga). Its fruit is composed of one swollen stalk (pedicel) which is formed by nutritional reserves rich in vitamin C and drupe (cashew nut). It is also rich in protein and lipids, but with smaller size. This paper focuses on investigating the applicability of the biplot graphical analysis in the process of selective breeding of cajuí population. The cajuí working apical diameter of peduncle, and variables of easy mensuration. Genotypes M40A, M23, M14, and M17 are similar to each other and they have high amounts of brown, apical and basal diameter of the peduncle, total weight, and peduncle length. They are considered as candidates selected for consumption in natura and industrial processing. The graphical analysis (biplot) showed robustness in the presentation of relationships between variables considered and the indication of the selection candidate genotypes in the population studied.

Early selection in a population of the mangaba (Hancornia speciosa Gomes)

“…Such results are not susceptible to extrapolation or juxtaposition, since they are the final product of the manifestation of particular genes and, depending on the degree of heritability of the variables, determined by different levels of intrinsic influence from the growing environment. In this work therefore, no comparisons with the results obtained from other genetic populations are reported; one exception can be justified, when the analysis is based on monogenic variables (MAIA et al, 2018;MAIA et al, 2019;PINHEIRO et al, 2019). It was therefore necessary to restrict this study to citing information, and to inferences of a theoretical nature.…”

“…A caracterização genética ou fenotípica de populações genéticas de quaisquer espécies são próprias e intransferíveis para outras populações, desta forma, as comparações de resultados entre estudos de natureza genética mesmo com emprego de abordagens de mesmo princípio matemático tornam-se impertinentes e equivocadas não sendo também passíveis de extrapolações ou justaposições uma vez que são produto final da manifestação dos genes particulares e, adicionalmente, determinados por níveis diferenciados de influência intrínseca do ambiente de cultivo a depender do grau de herdabilidade de suas variáveis, portanto, neste trabalho não se reportou, para efeito de comparações, a resultados obtidos a partir de outras populações genéticas. Uma ressalva pode ser justificada quando a análise recai sobre variáveis monogênicas (MAIA et al, 2018;MAIA et al, 2019;PINHEIRO et al, 2019). Passando-se assim, necessariamente, neste trabalho, a se restringir a citações de informações e inferências de referencial teórico.…”

Genetic diversity and structure in natural populations of Cajui from Brazilian Cerrado

“…has particular significance. The fruit and pseudofruit are rich in nutrients, being consumed in different ways by the local population in areas of natural occurrence of these species (Maia et al 2019). The term 'cajui' (small cashew fruit) is used to describe species of the genus Anacardium L. that produce small nuts (cashews) and peduncles (Borges et al 2018).…”
