MEXICO CITY (CIMMYT) — A common platform through which data on genetic resources can be disseminated to both crop researchers and breeders can strengthen research communities, according to authors of a soon to be published Crop Science study.
Conservation and exploitation of crop wild relative species is a key component in ensuring food security and improving current agricultural output. By identifying traits that express resistance or tolerance to stresses like pests or drought, breeders can incorporate this genetic material into genetic background stocks, which could help mitigate problems imposed by climate change, land degradation and population pressure. This is particularly important in countries that will be more severely affected by the threat of reduced yields.
While the underlying species differ, the approach taken ensured that tools were compatible across all database instances. The researchers found that Germinate offers a common platform that can improve the exploration and wider use of genetic resources in breeding programs globally.
