Abstract: This study aimed to use the canopy replacement technique to reduce the field evaluation time and to select promising cupuassu tree clones. The study was carried out under field conditions using fifteen-year-old trees. The crowns were replaced using 16 treatments (clones). The experiment was conducted using randomized blocks design with 18 replicates and one plant per plot, during a period of ten years. The following variables were evaluated: average number of fruits, fruit, seed and pulp production (kg/plant) … Show more

“…These F 1 progenies were evaluated in the field for 15 years. The plants selected from this population were cloned and two clonal evaluation trials were conducted, one using propagation by grafted seedlings, and the other using the top grafting technique (Alves et al 2020b). After 12 years of study, the five clones with best performance were identified based on the average response of the genotypes in these two trials.…”

“…The plants must be arranged in an organized manner in the field so that each clone is flanked by one of the other four clones on the four quadrants. That way, pollination efficiency is maximized, providing conditions necessary for plants to achieve full performance (Alves et al 2020b).…”

“…O cupuaçu tem aproveitamento integral pela agroindústria. A casca, que detém quase metade do peso total do fruto (ALVES et al, 2020a), pode ser utilizada como composto orgânico, produção de energia, alimentação animal ou mesmo humana (SALGADO et al, 2011). A polpa, alicerce atual da cadeia produtiva da espécie, presta-se para a fabricação de sucos, doces, geleias e outros produtos alimentícios (PEREIRA; ABREU; .…”

“…Posteriormente, formaram-se mais três BAGs: no Amapá (68 acessos), em Rondônia (36 acessos) e no Acre (12 acessos), todos compostos por acessos coletados nos respectivos estados . Após a formação das populações-base, o programa de melhoramento tem sido conduzido em três fases: a caracterização e avaliação dos acessos nas coleções de trabalho, a seleção de acessos superiores e a utilização destes genótipos para formação de populações melhoradas e desenvolvimento de cultivares, seminais ou clonais, visto a versatilidade propagativa da espécie (ALVES et al, 2020a;SOUZA et al, 2012).…”
