Cassava (Manihot esculenta), a major staple crop, is the main source of calories for 500 million people across the globe. No other continent depends on cassava to feed as many people as does Africa. Cassava is indispensable to food security in Africa. It is a widely preferred and consumed staple, as well as a hardy crop that can be stored in the ground as a fall-back source of food that can save lives in times of famine. Despite the importance of cassava for food security on the African continent, it has received relatively little research and development attention compared to other staples such as wheat, rice and maize. The key to unlocking the full potential of cassava lies largely in bringing cassava breeding into the 21st century. [More...]

Cassavabase Errata
An issue with genotyping data has been fixed in the database. Certain genotyping protocols stored the dosage information with inverted ref and alt values. All protocols are now using consistent values. We recommend to re-download the data if you use it locally. [May 2, 2022]
