Abstract
The relationship between grain yield and yield characters of two summer maize varieties under three planting densities was analyzed by the grey correlated degree method to provide a theoretical basis for breeding and high yield cultivation of summer maize.The results showed that the correlated degree between yield and various yield characters was grain ratecob weight per earear diameterear length1000-grain weightgrains per ear rowrows per eargrains per eargrain weight per ear,and there was a significant correlated degree between grain rate and yield in summer maize.
