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 relationship in Coffea species and parentage determination of interspecific hybrids using ISSR (Inter- Simple Sequence Repeat) markers

Genetics and Molecular Biology, 2003
Inter-simple sequence repeat (ISSR) markers were used to evaluate genetic divergence among eight Coffea species and to identify the parentage of six interspecific hybrids. A total of 14 primers which contained different simple sequence repeats (SSR) were

Breeding Programs Against Coffee Leaf Rust in Brazil: A Review

Journal of Agricultural Science
Leaf rust caused by Hemileia vastatrix Berk & Br. is the main disease that attack coffee plants all over the world. The disease causes 35-50% of yield loss in average in Brazil. The disease is present in all the countries that cultivate coffee (Coffea arabica L. and C. canephora L.).

The Effect of Coffee Pulp Composition with Consortia Variation of Indigenic Bacteria on Plant Growth of Coffee Breeding

International Journal of Engineering and Advanced Technology, 2019
This study aimed to determine formula and dosage of coffee pulpcompost that is appropriate to the growth of coffee in the nursery phase. The research treatment was a dose of coffee pulp compost with variations of bacterial consortia, using three treatments and one control including, 1) 150 grams of coffee pulp with variations of KA bacteria consortia ...

Breeding tools for durable resistance to nematodes (Meloidogyne spp.) of coffee varieties [PDF]

Plant Protection Science, 2002
Coffee is one of the world's largest traded commodities, produced in over 60 countries. Root-knot nematodes (Meloidogyne spp.) have become a major threat in all major coffee-growing areas. So far, more than fifteen species of Meloidogyne have been reported as pathogens of coffee (Coffea arabica L.). Nematocide treatments are only effective in the short
