Early selection in a population of the mangaba (Hancornia speciosa Gomes)
Cabral Maia, Maria Clideana; de Araújo, Lúcio Borges; dos Santos Dias, Carlos Tadeu; de Oliveira, Luís Cláudio; Lopes Vasconcelos, Lucio FlavoThe mangaba is a fruit tree with great potential for the northeast of Brazil. Due to the scarcity of improved cultivars, and as it is a species that is still in the process of domestication, exploitation has been based on rational and sustainable extractivism by farmer-gatherers. The aim of this study was to analyse the correlations between technological variables of the mangaba, and to carry out an early selec...
Repeatability estimation for mangaba selection using mixed models
Pinheiro, Diogo Santos; Cabral Maia, Maria Clideana; Pinto Mousinho, Francisco Edinaldo; de Oliveira, Luís Cláudio; Silva Rosado, Renato DomicianoThe Mangaba (Hancornia speciosa Gomes) is a fruit tree rich in such vitamins, iron, calcium and protein, and plays an important social, cultural and economic role for farmers in the Cerrado and Caatinga biomes of Brazil. The aim of this study was to estimate genetic parameters and genetic gains in the agrotechnological attributes of a breeding population of the mangaba from Embrapa Meio Norte. The variables und...
Repetibilidade de características quantitativas de frutos em seleções elite de ...
Cabral Maia, Maria Clideana; de Oliveira, Luís Cláudio; Lopes Vasconcelos, Lúcio Flavo; Lima Neto, Francisco Pinheiro; Yokomizo, Gilberto Ken-ItiA mangueira (Mangífera indica L.) é uma das principais fruteiras exóticas cultivadas no Brasil, sendo utilizada como um componente em vários arranjos dentro de sistemas produtivos, onde as cultivares geneticamente melhoradas são continuamente procuradas por parte dos produtores para a formação de plantios comerciais. Assim, objetivou-se com esta pesquisa descrever a estrutura de variâncias (estimação) e de médi...
Genetic analysis of half-sib progenies of Theobroma grandiflorum
Cabral Maia, Maria Clideana; Resende, Marcos Deon Vilela de; Oliveira, Luís Cláudio de; Alves, Rafael Moisés; Silva Filho, João Luis daThe cupuaçuzeiro (Theobroma grandiflorum), species native from the Amazon region, has been domesticated presenting a broad genetic variability, and thus favorable conditions for establishing of strategies to breeding and genetic conservation. The aim of this work was to evaluate 36 half-sib progenies of Theobroma grandiflorum obtained from a stratified mass selection in farmers areas based on primary components...
