RESUMO - Cruzamentos interespecíficos são utilizados em várias espécies para promover a introgressão de características que agregam valor agronômico a plantas cultivadas. Um clonde de C. canephora tetraploidizado foi um dos genitores da cultivar Icatu de C. arabica, uma das primeiras cultiva...
Genome-wide association studies (GWASs) allow for inferences about the relationships between genomic variants and phenotypic traits in natural or breeding populations. However, few have used this methodology in Coffea arabica. We aimed to identify chromosomal regions with significant associations betw...
Coffee Breeding programs have traditionally relied on observing plant characteristics over years, a slow and costly process. Genomic selection (GS) offers a DNA-based alternative for faster selection of superior cultivars. Stacking Ensemble Learning (SEL) combines multiple models for potentially even&...
ABSTRACT: With advancements in coffee cultivation, several traits may be considered in selection of plants, which must exhibit a set of favorable characteristics. The outturn index, defined as the relationship between the mass of mature fruit and processed beans, emerges as a key f...
In nature, the ability to avoid self-fertilization has evolved to prevent the deleterious effects of inbreeding. However, under cultivation conditions, self-incompatibility can reduce the pollination efficiency of Coffea canephora. The objective of this study was to characterize the self-incompatibility&#x...
A engenharia de grãos traz resultados importantes sobre a característica individual de cada genótipo, sendo assim, o objetivo deste trabalho foi de avaliar as propriedades de engenharia de diferentes clones de C. canephora no estado de Rondônia. Foram avaliados 86 genótipos ao longo...
Coffee is highly appreciated as stimulant. Brazil is the first producer and second consumer in the world. Flower evocation triggered by environmental signals is essential for adaptability and productivity, and despite that it is neglected and barely considered as a part of the repr...
O objetivo do trabalho foi de estudar o efeito da época de colheita do café conilon sobre o aparecimento do defeito verde, preto-verde e o tipo do café.
O objetivo deste trabalho foi o de estudar os efeitos da irrigação em diferentes períodos fenológicos do café conilon sobre o desenvolvimento do botão floral e floração.
