Abstract

The main factor that affects population's uniformity is invalid plant including inbred lines,barren stalk rate,diseases and pest insects plant in populations of different yield level.The lower of invalid plant rate,the higher of yield. A high single plant yield is very important to population's yield in high-Density condition.In order to decrease invalid plants in popualtions,pure seeds、carefully cultivation and Selecting big and strong seedlings is needed to guarantee high yield.
