Cereal Germplasm Resources1

摘要

The role of cereal germplasm banks is to collect, maintain, preserve, and distribute seeds representing the genetic diversity of crop species. While germplasm resources have traditionally been used in breeding efforts to improve a crop plant, they have also proved useful in both applied and basic research efforts to give insight into the biology of a crop plant (Harlan, 1975; Hyland, 1977; Sprague, 1980; Tanksley and McCouch, 1997; Damania, 2008; Johnson, 2008).
