论述吉林省玉米单产对全省乃至全国玉米及粮食产量的影响，分析了我国玉米产量水平低下的原因和东北春玉米尚有较大的增产潜力，并比较了中、美国家玉米品种的差异，提出了高产超高产育种计划：即高产超高产育种方向、目标和选系方法。认为稳产育种与高产育种应同步进行；中低产田以Lan.类群与塘四平头类群为杂优模式对，向适应性强、稳产杂交种方向选育；高产田以Reid类群与旅大红骨类群为杂优模式对，向超高产杂交种方向选育。

This paper discussed the effects of maize per unit area yield on maize and grain output of Jilin province, even the whole China, analyzed the reason of China maize's low yield of and the big increasing potential existed in Northeastern Spring corn, analyzed and compared the discrepancy of variety between China's and America's maize, advanced the project that breeding high yield and super-high yield maize, namely, the direction and goal for high yield and super -high yield breeding and the selecting process of inbred line . We deemed that the steady yield breeding and high yield breeding should be commenced at the same time: breeding hybrid with strong adaptability and stability yield, according to the heterotic patterns of Lan.×Tang group, in medium-low yielded farm land, and breeding hybrid with super high yield, according to the heterotic patterns of Reid×Lv group, in high yielded farm land.
