Genetic diversity of coffee germplasm in Sierra Leone: implications for conservation and breeding programs

Beverage Plant Research, 2023
Global coffee production is dominated by Coffea arabica (Arabica coffee) and C. canephora (Robusta coffee) due to their relatively high-yielding and quality attributes as opposed to other coffee species.

Genetic diversity of ex-situ conserved Arabica cofee (Coffea arabica L.) accessions in Ethiopia as revealed by simple sequence repeats markers

Coffee and Cocoa Research Journal, 2023
So far, there has been limited use of molecular markers in arabica coffee breeding program in Ethiopia. The objectives of this study were to explore the effectiveness of simple sequence repeats markers (SSRs) in detecting polymor- phism and to assess ...

G x E interactions on yield and quality in Coffea arabica: New F1 hybrids outperform American cultivars [PDF]

, 2020
Conventional American cultivars of coffee are no longer adapted to global warming. Finding highly productive and stable cultivars in different environments without neglecting quality characteristics has become a priority for breeders.

Strategies for Robusta Coffee (Coffea canephora) Improvement as a New Crop in Colombia

Agriculture, 2022
Robusta coffee is mostly grown in Africa and Asia and parts of tropical America, but not yet in Colombia. The crop has potential in lowland areas of this traditional Arabica coffee producer. Compared to Arabicas grown in highland areas, the Robustas have

A single polyploidization event at the origin of the tetraploid genome of Coffea arabica is responsible for the extremely low genetic variation in wild and cultivated germplasm [PDF]

, 2020
The genome of the allotetraploid species Coffea arabica L. was sequenced to assemble independently the two component subgenomes (putatively deriving from C. canephora and C.

Starmaya: The first arabica F1 coffee hybrid produced using genetic male sterility [PDF]

, 2019
In the present paper, we evaluated the implementation of a seed production system based on the exploitation of male sterility on coffee. We studied specifically the combination between CIR-SM01 and Marsellesa® (a Sarchimor line), which provides a hybrid ...
