Reproducibility of the RAPD marker and its efficiency in coffee tree genotype grouping analysis

open access: yesCrop Breeding and Applied Biotechnology, 2002
The genetic diversity of Coffea arabic L. cultivars is relatively narrow and its assessment and increase is important for breeding. Fifty two arbitrary primers were used to evaluate the reproducibility and the influence of the number of RAPD (Random ...

The polyphenolic and hydroxycinnamate contents of whole coffee fruits from China, India and Mexico [PDF]

open access: yes, 2013
Air dried whole coffee fruits, beans and husks from China, India and Mexico were analysed for their chlorogenic acids (CGA), caffeine, and polyphenolic content. Analysis was by HPLC and Orbitrap exact mass spectrometry.

Genomic Offset Analyses: Mind Your Climate Variables

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Recent methods based on genomic offset (GO) statistics aim to quantify the risk of non‐adaptation of populations to future climates. This study assesses how well genomic offset values correspond to population variation in fitness, depending on the methods and climate data used.

Autotetraploid Coffea canephora and Auto-Alloctaploid Coffea arabica From In Vitro Chromosome Set Doubling: New Germplasms for Coffea

open access: yesFrontiers in Plant Science, 2020
Polyploidy is more than two chromosomal sets per nucleus, as the allotetraploid Coffea arabica. Due to allotetraploidy, C. arabica shows different phenotypes compare to diploid Coffea species, highlighting by beverage quality produced from its grains ...

Analysis of nucleotide diversity in Coffea spp. (W153) [PDF]

open access: yes, 2011
Marker-assisted selection becomes a reality for many crops; in perennial crops, the utilization of molecular markers in breeding programs can speed up genotype selection. However, the most important commercial coffee species - allotetraploid C. arabica -

Weed Management Influences the Accumulation of Organic Matter in the Soil and Productivity in Coffee Farming

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
The management of weeds can influence organic matter (OM) and organic carbon (OC) levels, impacting the productivity and sustainability of coffee plantations. This study aimed to evaluate OM and OC levels in coffee soils under different weed management practices and their influence on coffee tree physiology and productivity. The experiment featured six

Assessing the Impact of Nitrogen Trade‐Off Between Coffee Tree Productivity and Bean Sensory Attributes to Produce Australian ‘Specialty Coffee’

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 2, June 2026.
Effective nitrogen management is essential for sustainable coffee production and enhanced yield. This study evaluated the effects of five nitrogen application rates (per annum; N1: 120 kg/ha, N2: 240 kg/ha, N3: 360 kg/ha, N4: 480 kg/ha, N5: 600 kg/ha) applied in equally distributed monthly rates over 2 years, from flowering to harvest, on Coffea ...

Triple plagiotropic branch in coffee: a new promising mutant?

open access: yesCrop Breeding and Applied Biotechnology, 2017
Coffee tree is a shrub with dimorphic branches. The orthotropic stem grows vertically with two near-horizontal plagiotropic branches, per node, in opposite phyllotaxy. The consecutive nodes of the orthotropic stem are organized in parastichies. We report

Surface roughness of supra-nano spherical filled and nanohybrid composite resin after Coffea arabica immersion: an experimental study

open access: yesPadjadjaran Journal of Dentistry
Introduction: Supra-nano spherical filled composite resin (Omnichroma, Tokuyama, Japan) with sol-gel method has 0.26 μm filler size, while nanohybrid composite resin (ENA HRi, Micerium, Italy) has 0.2-1 μm filler size. Nanofillers enhance resistance from
