Diversity evaluation of wheat germplasm resources in China

A great number of wheat genetic resources are distributed in China, and more than 40,000 accessions have been conserved in the National Crop Gene Bank. The diversity of these wheat genetic resources was evaluated for the following fields: distribution areas and growth environments; collection status; genetic diversity in agronomic characters, grain quality, resistance to diseases, pests and environmental stresses, and crossability. According to the results of diversity evaluation, some collections with desirable characters have been obtained.
