Multiple Traits Selection Strategies: A Proposal for Coffee Plant Breeding

Agronomy, 2023
Experiments with progenies of perennial species such as coffee are generally affected by the heterogeneity of residual variances between information repeatedly collected in space and time on the same individual. In this study, we propose an index that considers the individual heritability of multiple traits for progeny selection and evaluate the ...

Heritability and Combining Ability of Some Vegetative and Yield Characteristics of Promising Arabica Coffee Varieties in Indonesia

Coffee and Cocoa Research Journal, 2022
Breeding for high yielding and good quality arabica coffee is the direction of the coffee breeding program in Indonesia. Hybridization becomes the important step to select promising genotypes from the genetic variability to achieve those goals.

Potential of the Colombian Coffee Collection as a Source of Genetic Resistance to Colletotrichum kahawae JM Waller and PD Bridge

Agronomy
Coffee berry disease (CBD) is not present in the Americas and presents a potential risk for growing coffee. Therefore, Colombia, which has been in scientific cooperation with the Centro de Investigação de Ferrugens do Cafeeiro (CIFC) of Portugal for more

Coffee pulp supplementation prior to breeding improves oxidative status without affecting fertility of primiparous ewes

Revista Colombiana de Ciencias Pecuarias, 2019
Background: Coffee pulp has a high content of antioxidants capable of modifying the oxidative status in small ruminants. However, high amounts for a prolonged time can reduce fertility. Objective: To determine the effect of two inclusion levels of coffee

Optimizing the Genetic Transformation of Coffea arabica Using Agrobacterium tumefaciens

International Journal of Plant Biology
The genetic transformation of Coffea arabica L. is an alternative strategy for obtaining plants with agronomic traits of interest that is less time-consuming than conventional breeding methods. Given the importance of coffee cultivation in Colombia, this

Physical and Organoleptic Quality Attributes of Lowland Coffea arabica Genotypes Introduced and Grown in Southwestern Ethiopia

Journal of Food Quality
Ethiopia is the center of origin and genetic diversity for Arabica coffee (Coffea arabica L.). The country’s coffee sector relies on this genetic diversity to produce high-quality coffee with unique flavor profiles.

Genetic Compositions and Environmental Factors Influenced Raw and Cup Quality Attributes of Limmu Coffee Hybrids in Southwestern Ethiopia

Journal of Food Quality
Coffee quality is a complex trait influenced by both genetic compositions and environmental factors. In Ethiopia’s Limmu coffee-growing area, the joint effect of genotype and environment on raw and cup quality attributes is still not well understood ...
