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...]

You can search the cassava HapMaps whole genome sequencing data from Bredeson et al (2016) and Punna et al (2017) using Jbrowse by clicking the link above or by accessing the "Analyze" menu, "Hapmap Jbrowse" [June 6, 2017]
You can make a list of trials from the search wizard to create a combined training dataset. [Feb 24, 2017]
For time consuming tasks in the solGS workflow, you can queue the tasks to run in the background and be notified by email when completed. [April 28, 2016]
The Search "Wizard" has been improved with faster speeds and new features, such as combining lists using intersection or union operators, starting with lists of accessions, and more. [February 21, 2016]
