摘　　要：本研究选用20个青贮玉米品种，于2009～2010年连续2年在黑龙江省畜牧研究所试验基地，研究青贮玉米的9个农艺性状与产量的关系，找出对产量影响较大的农艺性状因子，为青贮玉米筛选推广提供理论依据。对青贮玉米植株形态性状指标的主成分，结合产量相关性分析，以确定主导产量的因子。结果表明：产量为第1主成分，籽粒形成相关性状为第2主成分，叶片形态因子为第3主成分。在齐齐哈尔地区产量性状表现较好的品种有中原单32、东青1号、东农252、海玉9号。This study use 20 silage maize varieties, from 2009 to 2010 for 2 years in Heilongjiang Animal Husbandry Institute base, study of silage maize 9 agronomic characters and the relation between the yield, and find out the greater influence on yield of agronomic characters factor, silage maize screening for promotion to provide the theory basis. Silage maize plants of morphological characters of the main component of the index, combining with the production the correlation analysis to determine the dominant factors of production. The results show that the yield of first principal components, grain formation related properties for the second principal component, leaf form factor for the third principal component, the better maize varieties of yield have Zhongyuandan 32,Dongqing No.l,DongNong 252,HaiYu No.9 in QiQihar area
