Experimental F1 hybrids in the field
Update to Next-Generation F1 Hybrid Varieties
Today’s best coffee varieties are no match for the environmental threats of the 21st century—changing weather patterns, increased temperatures, and new disease and insect prevalence. This creates conditions for a potentially disastrous decline in supply in the coming decades. Focusing on coffee genetic improvement through the breeding of new varieties and advanced research in the lab to identify key genes and markers is vital to ensure the future of coffee. This is the cornerstone strategy of our work.
Around the world, less breeding on coffee is done now than 50 years ago, but the threats now are greater In fact, coffee is one of the most under-innovated crops in the world. Today, less breeding is done on coffee than on watermelons! World Coffee Research’s breeding program is the only international, precompetitive coffee-breeding program in the world.
In 2016, we created 46 new F1 hybrids, derived from crosses between 8 wild Arabicas in the WCR Core Collection and three rust-resistant Sarchimor varieties (Obatá, Marsellesa and IAPAR 59) as well as Geisha.
These new F1 hybrids will be studied in the field for 4–5 crop cycles,
between 2017 and 2021. All of the varieties are
currently undergoing field evaluation at the WCR research farm, Flor
Amarilla, in El Salvador. The best hybrids (2 or 3 in total) will
be selected and released for farmers in Central America in time for
vegetative multiplication on a commercial scale in 2023. The varieties
will also begin testing in Rwanda in 2018.
Varieties will be selected on the basis of:
High, stable yields
Resistance to diseases like leaf rust
In addition, 15 of the crosses have been shipped to Rwanda for local selection, and 13 to Zambia for evaluation in hot, dry climate expected to be the norm for coffee production zones by 2050.
