摘要
以正在参加黄淮海国家糯玉米区域试验的19个新品种为材料,利用灰色关联度分析方法,对11个农艺性状与鲜穗产量进行了关联度分析。结果表明,糯玉米农艺性状与产量关联度的大小依次为穗粗＞穗行数＞穗长＞株高＞收获期＞行粒数＞轴粗＞穗位高＞鲜百粒重＞鲜出籽率＞秃尖长。穗粗、穗行数、穗长、株高是影响糯玉米鲜穗产量的主要因素,而鲜穗百粒重、鲜出籽率、秃尖长度对产量影响则较小。但影响鲜穗产量的主要因素在不同产量水平品种中存在一定差异。
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 beating 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.
