Research Project: Transfer and Evaluation of Coffee Germplasm for the United States

Location: Tropical Plant Genetic Resources and Disease Research

Project Number: 2040-21000-018-010-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Aug 24, 2023
End Date: Aug 23, 2026

The goal of this project is to increase the diversity and understanding of coffee genetic resources available in Hawaii and the U.S. Specific objectives are to: 1) Transfer seeds of inbreed coffee accessions; 2) Transfer clonal coffee accessions; 3) Prioritize additional accessions for transfer; and 4) Genetically characterize and discover new sources of important genetic material.

Coffee germplasm of important commercial cultivars and coffee species and associated information will be transferred from HARC to PBARC in phases. Seed propagated coffee will be bagged prior to flowering to ensure self-pollination. Upon harvest, the seeds will be cleaned and sent to PBARC. Clonally propagated material will be harvested and sent to Hilo to be grafted onto rootstock. Other important accessions will be evaluated and prioritized for collection from other sources. In addition, HARC and USDA ARS personnel will work closely to genetically and molecularly characterize the germplasm to characterize the material and potential gaps. Also, to discover potential breeding markers for important agricultural traits.
