Genome association of carbohydrate metabolites provides new insights toward functional breeding in coffee

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Coffee is one of the world's most widely consumed beverages, derived mainly from Coffea arabica, known for its superior flavor, and Coffea canephora (Robusta/Conilon), valued for its resilience and higher caffeine content. Functional breeding aims to develop cultivars that combine productivity and stress tolerance with improved health‐related ...

Yield, stability, and plasticity of Arabica coffee genotypes under contrasting pruning systems

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Coffee yield instability caused by biennial bearing causes coffee yield instability, reducing production predictability and farm income. Biennial drastic pruning (Zero Crop), which alternates harvest and no‐harvest years, has been proposed to reduce this instability, but its benefits depend on genotype performance under contrasting management.
