Abstract: Forage grass is the cornerstone of animal husbandry. However, the shortage of forage grass caused by the lack of elite varieties and simple planting structure has been a bottleneck for the forage grass industry. Therefore, the productive yield potential of new forage grass species besides developing traditional forage grass should be mined. New forage grasses developed in recent years have great advantages over the traditional forage grasses in their feeding value, including yield, nutritional quality, adaptability, and stress resistance. In this review, we summarized the research progress, development trend, and core competitive value of several new forage grasses, including bermudagrass (Cynodon dactylon), triticale (×Triticosecale Wittmack), quinoa (Chenopodium quinoa), forage rapeseed (Brassica napus), grain amaranth, sesban (Sesbania cannabina), and wild soybean (Glycine soja). We also discussed the basic biological problems in new forage breeding. Finally, we provided suggestions and strategies for innovation of the new forage grass and sustainable development of forage grass industry, ensuring food security.

Key words: new forage grass, molecular design breeding, basic biological problems, food security
