Abstract: In order to research relation of fresh ear yield and main agronomic characters, we provide a theoretical basis to the waxy corn breeding. 10 agronomic characters and fresh ear yield of 14 combinations in fresh-eat waxy corn in Southwest corn regional trial in 2012 were analyzed with grey relation grade analysis. The results showed: relational degree order of agronomic characters and fresh corn yield were as follows: row per ear > ear diameter > ear length > kernel per row > sprouting-harvest > plant height > bald tip length > kernel rate > 100-kernel weight > ear height. Row per ear was the main factor affecting fresh yield of waxy corn, and the second was ear diameter and ear length, but the ear height had less effect on yield.
