Abstract： Biotech seed industry is a strategic core industry. Biotechnology combined with digital technology has promoted the seed industry into an intelligent era, and the breeding paradigm has changed from “experimental selection” to “computational selection”. Biotech seed industry has become a research and development intensive industry, and the market is highly concentrated, which is controlled by large multinational enterprises. The scientific and technological output of China and the United States is in the first echelon, and the number of papers and authorized patents ranks among the top two in the world. From the perspective of core competitiveness, the United States is a global leader with monopoly advantages in original basic research and key technology. China has made great progress in the application of breeding technology, but it still needs to breakthrough in basic theory research, key technology development, and high value seed product.

Abstract： Tall wheatgrass (Elytrigia elongata) is a perennial cool-season bunchgrass with high productivity and tolerance to salt and alkali, waterlogging, and drought. Since first introduced into China in 1950s, tall wheatgrass has long been used as a wild parent for distant hybridization with wheat (Triticum aestivum). During 1980s─1990s, a few tall wheatgrass varieties were introduced to China as forage grass, nonetheless, currently they are still not widely cultivated and no variety was certificated. In 2020, Zhensheng Li put forward a proposal to construct “Coastal Grass Belt” on saline and alkaline soils in the Circum-Bohai sea region, which provides an opportunity for the industrialization of tall wheatgrass in China. This paper introduces the background, main characteristics, history and status of tall wheatgrass and put forward suggestions for industrialization of tall wheatgrass in China. In order to promote utilization of tall wheatgrass in China, the authors suggested constructing demonstration models of “Coastal Grass Belt” and demonstration farms for livestock in the “Coastal Grass Belt” targeted area. Leading companies should be fostered to form a complete industrial chain of “leading companies + professional cooperatives/ large growers”. In addition, basic research, breeding, and seed industrialization should be carried out and accelerated. Meantime, policy and funds from government’s support should also be considered. “Coastal Grass Belt” can not only solve the shortage of high-quality forage grass in China, but also establish ecological barrier and protect the ecological environment.
