Identification of two monoterpenes and their coding genes in Coffea arabica L. associated with the attraction of the coffee berry borer (Hypothenemus hampei)

Journal of Plant Interactions
The coffee berry borer (CBB) is the most significant pest affecting coffee in Colombia and, globally, attracted primarily to volatiles from ripe fruits.

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 Genetic Breeding at IAPAR

Cropp Breeding and Applied Biotechnology, 2001
This paper introduces the coffee genetic breeding research program developed by IAPAR (Agronomic Institute of Parana, Brazil) which started in 1973. The characteristics of a breeding program for a seed-propagated perennial plant with a biennial production and the difficulties in assessing yield and longevity due to the time limitations they impose on ...

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

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.

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

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 ...
