Advanced strategic research to promote the use of rice genetic resources por Lee, Jae-Sung, Chebotarov, Dmytro, Platten, John Damien, McNally, Kenneth, Kohli, Ajay

“…However, in spite of the success in collection and conservation, only a small portion of the genetic diversity has been used in crop breeding programs. As climate change-induced new or enhanced constraints seriously hamper crop productions, researchers and breeders should be able to swiftly choose an appropriate set of genetic resources from the genebank and use them for improving crop varieties. …”
