中单206是中国农业科学院作物所选育的高赖氨酸玉米。1985年全国高赖氨酸玉米杂交种区域试验表明,其籽粒产量比普通玉米中单2号低3.06％,但全籽粒赖氨酸含量为0.47％,相当于中单2号的2.13倍。适宜种植区域与中单2号相同。近年来全国进行的养猪试验表明,饲料中粗蛋白质含量在 Zhongdan 206 is a high-lysine corn selected from the crops of the Chinese Academy of Agricultural Sciences. In 1985, the national high lysine corn hybrids regional test showed that the grain yield was 3.06% lower than that of ordinary maize Zhongdan 2, but the whole grain lysine content was 0.47%, which was equivalent to 2.13 times of that of Zhongdan 2. The suitable planting area is the same as Zhongdan 2. In recent years, pig experiments conducted across the country have shown that crude protein content in feed is high
