At present,there are researches both at home and abroad about the relationship between nutritional quality and physiological active substances of rice and human physiological activities. Through conventional breeding,gene mutation technology,and molecular-assisted selection( MAS) technology,it is feasible to select and breed new rice varieties and plants with certain health care functions.展开更多
