Molecular analysis of introgressive breeding in coffee (Coffea arabica L.)

Theoretical and Applied Genetics, 2000
Nineteen arabica coffee introgression lines (BC1F4) and two accessions derived from a spontaneous interspecific cross (i.e. Timor Hybrid) between Coffea arabica (2n=4x=44) and C. canephora (2n=2x=22) were analysed for the introgression of C. canephora genetic material. The Timor Hybrid-derived genotypes were evaluated by AFLP, using 42 different primer

Caffeine inheritance in interspecific hybrids of Coffea arabica x Coffea canephora (Gentianales, Rubiaceae)

Genetics and Molecular Biology, 2008
Caffeine inheritance was investigated in F2 and BC1F1 generations between Coffea arabica var. Bourbon Vermelho (BV) and Coffea canephora var. Robusta 4x (R4x). The caffeine content of seeds and leaves was determined during 2004 and 2005.

Relationship Analysis Between Leaf-Stomata Characteristics with Cocoa Resistance to Vascular-Streak Dieback

Coffee and Cocoa Research Journal, 2016
Characteristics of leaf-stomata indicate having relationship with  the resistance of  cocoa  to  vascular-streak  dieback  (VSD)  caused  by  Ceratobasidum  theobromae. This  research  has  objective  to  identify  the  relationship  between leaf-stomata

Research results on robusta coffee breeding in Vietnam

Vietnam Journal of Science, Technology and Engineering, 2017
In the research and development of coffee trees in Vietnam, particularly breeding is one of the most important activities and always prioritized by the Government. Since 1976, the Western Highlands Agriculture and Forestry Science Institute (WASI, former Coffee Research Institute), has invested a lot of efforts in selecting and creating new coffee ...

Genetic Control of Resistance to Colletotrichum kahawae in Coffee: Evidence of Polygenic Inheritance and Differential Host Genotype Responses to Pathogen Isolates

Plants
Colletotrichum kahawae is the causal agent of coffee berry disease (CBD), a disease restricted to African countries producing C. arabica, which affects coffee production and is a potential phytosanitary threat for coffee plants growing at other latitudes.

Non-Destructive Estimation of Leaf Size and Shape Characteristics in Advanced Progenies of Coffea arabica L. from Intraspecific and Interspecific Crossing

Plants
Non-destructive measurement of leaf size based on leaf length and/or width is a simple, economical, and precise methodology. Leaf morphometric indicators were measured on 55 coffee progenies obtained from intraspecific and interspecific crosses.

Metabolomic Markers for the Early Selection of Coffea canephora Plants with Desirable Cup Quality Traits

Metabolites, 2019
Genetic improvement of coffee plants represents a great challenge for breeders. Conventional breeding takes a too long time for responding timely to market demands, climatic variations and new biological threads.
