According to news on April 8, 2021, recently, the world's barley high-density liquid phase SNP chip-Barley 40K SNP (Single Nucleotide Polymorphism) chip was successfully released. The liquid chip was developed by the team of Professor Song Weining of Northwest Agriculture and Forestry University and Borui Di Biotechnology Co., Ltd., breaking through the key bottleneck limitations of the previous global barley chip lacking my country's germplasm resources, wild resources and highland barley resource genome information, and stored 40,000 Multiple barley genetic information provides support for the selection and breeding of excellent barley varieties.

    Professor Song Weining is mainly engaged in the research of wheat molecular biology, genomics and genetic improvement, plant stress genomics and plant origin and domestication. He represented my country in the world's complete version of the "Chinese Spring" genome map of hexaploid wheat led by the International Wheat Genome Sequencing Alliance. He finally completed the research successfully in 13 years and was awarded the top ten rural news figures in China in 2019. title.

    In this barley 40K SNP chip research and development, Professor Song Weining re-sequenced the whole genome of 155 different types of barley materials (including wild barley, farm-grown and cultivated barley varieties, and highland barley) from different ecological regions and different types of barley in the world. Data, selected highly representative and highly polymorphic loci from the massive SNP data set, integrated information about hundreds of identified important traits related loci (including barley drought-resistant SNP loci), using Boruidi’s GenoBaits technology successfully developed the world's first barley high-density liquid phase SNP chip.
This chip has independent intellectual property rights, contains 40,519 SNP sites, has the advantages of uniform coverage of the whole genome, high polymorphism, high specificity, and strong versatility. At the same time, it adopts liquid-phase chip technology and has low cost , High throughput, high sensitivity and parallel detection and other advantages.

    Barley is the fourth most important gramineous crop in the world. In addition to human and animal consumption, it is also an important raw material widely used in the food and beverage industry, and it can be grown in harsh environments such as drought and saline. In my country's Qinghai-Tibet Plateau, highland barley (naked barley) has extremely important and special economic and cultural value.
The barley chips currently on the market for theoretical and breeding research are produced in Europe and the United States. They are still traditional solid-phase chips, and they are not as good as new-generation liquid-phase chips in terms of use cost, throughput, and flexibility. More importantly, these chips do not contain the genome information of wild materials, nor the genome information of Chinese barley, especially the highland barley. The depth and breadth of the genome coverage cannot match the new generation of barley liquid-phase chips derived from resequencing data. Therefore, the new barley chip will be a powerful tool for barley molecular breeding, design breeding and theoretical research, and has a broader application prospect.
Agriculture is the foundation of the country, and planting is the first of agriculture. The Central Economic Work Conference pointed out that the current development of my country's seed industry is facing new requirements, new opportunities, and new challenges. It is necessary to solve the problem of "stuck neck" in the seed industry. During the "14th Five-Year Plan" period, the seed industry should be regarded as a key task for agricultural science and technology research and agricultural and rural modernization, strengthen the protection and utilization of germplasm resources, pay attention to the research and development of new breeding technologies, and strengthen the scientific and technological support of the seed industry.
    The successful development of barley 40K SNP chip will break through the key bottleneck limitations of the previous global barley chip’s lack of my country’s germplasm resources, wild resources and highland barley resource genome information, and will provide opportunities for barley molecular breeding, design breeding, Germplasm identification and analysis, high-throughput genotyping, QTL mapping, genome-wide association analysis, and genome selection provide important tools, and also lay the foundation for the development of innovative barley breeding technology and breeding breakthroughs.
