最近,美国科学家通过将本国玉米主产区传统近交系玉米品种与20世纪70年代培育出杂交玉米品种(含有来自美国东部地区一种名为“gamagrass”野生草科基因)进行杂交,成功培育出14种含有“Tripsacum dactyloides”基因的有利于人体心脏健康新型玉米品种。由于是通过传统育种方法培育,新型玉米品种可以在抵制生物技术的市场上具有广泛 Recently, U.S. scientists have successfully cultivated a cross between the traditional maize inbred line of maize from its main corn producing area and the hybrid corn cultivated in the 1970s (containing a wild grass gene called “gamagrass” from the eastern United States) Fourteen New Corn Varieties for Human Heart Health Containing the “Tripsacum dactyloides” Gene. Because it is cultivated through traditional methods of breeding, the new varieties of maize can have a wide range of markets that resist biotechnology
