Breeding and Biotechnology of Coffee

2000
The taxonomic position of some Coffea species is controversial. Many of the known species have been discovered along harvests made in the tropical forests of Africa since 1940. The literature suggests that the true Coffea species are those from central and equatorial regions of Africa, including Madagascar and the neighbouring islands close to Indian ...

Molecular Breeding in Coffee (Coffea Arabica L.)

2000
The cultivated coffee Coffea arabica L. (2n=4x=44) is an allotetraploid species native to Africa, containing two diploid genomes that originated from two different diploid wild ancestors (2n=2x=22), C. canephora and C. eugenioides or ecotypes related to those species (Lashermes et al., 1999).

Breeding for coffee quality [PDF]

, 2012
In line with the focus on specialty coffee, we will concentrate on the breeding of Coffea arabica. Contrary to what many may believe, breeding for coffee quality is a relatively new initiative. The challenges and opportunities that breeders face when selecting varieties for high quality are discussed. In the coffee production sector, when talking about

Coffee Selection and Breeding

1985
In spite of the tremendous genetic potential revealed by recent botanical and (cyto)genetic research into the genus Coffea (see Chapter 2), coffee breeding is still largely restricted to the two species, Coffea arabica and C. canephora, that dominate world coffee production.

Inheritance of resistance to coffee wilt disease (Fusarium xylarioides Steyaert) in Robusta coffee (Coffea canephora Pierre) and breeding perspectives [PDF]

Tree Genetics & Genomes, 2012
Knowledge on heritability is essential for selecting varieties resistant against coffee wilt disease caused by Fusarium xylarioides, which is currently devastating coffee in East and Central Africa. Variability of the resistance against coffee wilt disease in Coffea canephora and its inheritance were investigated in three experiments corresponding to a

DNA Markers for Coffee Tree Breeding

2000
Coffee cultivation in the world has benefited greatly from the successful breeding programmes, which have given the farmers productive cultivars adapted to specific cropping conditions. For example, presently in Brazil the improved arabica coffee cultivars (Coffea arabica L.) produces three to four times more than the cultivars used in the past ...

Genetic Resources and Breeding of Coffee (Coffea spp.)

2019
Coffee is an important agricultural export commodity in many Asian, African and Latin American countries. It provides a livelihood for more than 125 million people worldwide. The genus Coffea comprises more than 125 species of which only 2 species Coffea arabica (arabica coffee) and C. canephora (robusta coffee) are commercially cultivated for beverage

Developments in molecular breeding techniques in Robusta coffee

2018
As a perennial crop, faster breeding methods are needed for coffee to be able to cope with the challenges of climate change that lie ahead. This chapter focuses on the state of the art of developed molecular tools, characterized traits, quantitative trait loci and candidate genes already described for Coffea canephora (Robusta coffee), which accounts ...

A tentative breeding method for Robusta and other allogamous coffee species

Euphytica, 1954
In Indonesia the usual method of breeding Robusta coffee consists of crossing carefully selected trees in order to ascertain which combinations give the best progenies. The most successful combinations are repeated on a large scale, the crossing partners being represented by clones.
