Study on Breeding for Medium and Earlier Matured Super-high-yield Corn

In this article,we discussed some potential factors on improving corn yield and mainly eyed on the creation of the rural breeding materials and developing corn inbred line maize for medium and earlier matured super-high-yield corn breeding,our opinions are:(1)to improve the yield of corn by increase the biological output of single plant and populations (2)to make sure super-high-yield hybrid matured earlier by strengthening internode length,not by adding plant leaves (3)to insure the medium and earlier mutured super-high-yield hybrid has good lodging-resistence by selecting hydrid that has good developmental root system and tough stem.
