Mung bean, adzuki bean and other Vigna food legumes are rich in protein, dietary fiber, vitamins and other nutritional elements and bio-active substances. They have both the characteristics of medicine and food function, and play an important role in people's nutritional and health care needs and dietary structure adjustment. In recent years, the demand for Vigna food legumes all over the world has been increasing rapidly.
China is the origin center of adzuki bean and some other Vigna food legumes and has a large number of germplasm resources. The existing research worldwide has laid a theoretical foundation to some extent for the identification and utilization of Vigna food legumes germplasm resources. However, there are still some problems such as unclear genetic background of the resources and lack of excellent materials for breeding. It is imperative to systematically evaluate the genetic background of Vigna food legumes germplasm resources, clarify the genomic selection sites and variation information in the breeding process, and deeply analyze the molecular basis of domestication and breeding progress
The Cereals and Oil-Crops Institute of Hebei Academy of agriculture and Forestry Sciences has long been committed to the innovation and creation of superior germplasm of mung bean and adzuki bean, the cultivation of new varieties, gene mapping of important traits, molecular marker assisted selection, gene cloning and gene function verification. Important progress has been made in the identification of excellent germplasm resources such as flowering stage, insect resistance and drought resistance of Vigna food legumes and the mining of related genes. Relevant results have been published in academic journals such as Theoretical and Applied Genetics and Scientific Reports. And based on those research, 6 national invention patents have been granted.
We would like to cooperate with foreign research institutions and scientists in those studies. The research contents include: evaluation of the genetic background of Vigna food legumes germplasm resources by using genome and comparative genomics analysis, mining the main genes of excellent resources, and molecular marker assisted breeding of new Vigna food legumes varieties.
