Currently about 80 thousand accessions belonging to 27 species for these crops were collected and conserved in the National Genebank of China. Morphological variation are observed in plant types, flower colours, panicle shapes, seed colours, seed shape and seed size in accessions.  Molecular characterization  Genetic diversity of collections of underutilized grain crops were assessed with molecular markers such as AFLP  and SSR. These analyses revealed the scope of the diversity, structure of population, relationships between accessions and between species, and origin and evolution of relevant crop in China Adaptation to climate change  Underutilized grain crops are characterized by short growing period and strong adaptability to the poor ecological environments. Millets and oats could grow in very dry conditions, while buckwheat and common millet can be harvested in a very short period of growing season. Resistance to drought, saline and alkali are another important characteristics associated with the adaptability to climate change.  Promoting for nutrition and dietary diversity Underutilized grains contain high level of protein, fat, and various microelements that contribute to nutrition and dietary diversity of local farmers, particularly the women and children. In China, the annul cultivation area for those crops reach over 1 million ha., which greatly contribute to the diversified food supply for people in remote areas with vulnerable agroecological environments.
