Project Type: Trust Fund Cooperative Agreement
Start Date: Oct 3, 2022
End Date: Oct 2, 2026
Objective:
The objective of this proposal is to utilize the existing breeding program at HARC to establish a pipeline to produce Coffee Leaf Rust CLR-resistant coffee cultivars, maintain the uniqueness and high quality of local beans, and prepare for possible invasion of new CLR strains.
Approach:
Select Coffee Leaf Rust CLR-resistant coffee cultivars with high cupping quality from the existed recurrent selection populations derived from the crosses between Catimor and Hawaiian commercial cultivars. Create and select new cultivars through crosses of new sources of CLR-resistant varieties with Hawaiian commercial cultivars. Develop marker assisted breeding systems for CLR-resistance and high cupping quality. Develop chemical markers predictive of coffee cupping quality. The goal of this research will be to establish an efficient breeding pipeline to incorporate CLR-resistance into existing and local elite cultivars.
