Abstract: This paper, using nineteen new varieties that were testing in huang huai hai waxy reginal-test of china, analyze the relaionship of 11 agronomic charactics and fresh ear field in wax maize hybrids by the grey related degree analysis. The result showed that relative importance order of waxy yield was ear diameter﹥kernel row of ear﹥ear length﹥plant height﹥germination-reap﹥kernel row number﹥axis diameter﹥ear position﹥100- ernel weight﹥rate of bearing kernel﹥bald tip length.ear diameter ,kernel row of ear , ear length and plant height were the main influences to waxy field . effection of 100- kernel weight, rate of bearing kernel and bald tip length were smaller.But the main factors of fresh ear field were different in rank of different field varieties.
