摘　　要：为了筛选适宜浙中地区种植的优良玉米品种,通过相关分析、主成分分析对11个引进玉米品种的农艺性状进行分析,并对这些品种的适应性进行综合评价。结果表明,引入品种较对照都具有良好的农艺性状、品质以及抗病性。7个农艺性状的变异系数在7.31%~13.82%之间,其中百粒重、穗位高、穗行数的变异系数较大,株高与果穗鲜重呈极显著正相关(p<0.01),与穗位高、穗行数以及穗长显著正相关(p<0.05);主成分分析中,3个主成分的累积贡献率为86.67%。综合鲜穗产量、品质和抗病性,从11个引进品种中筛选出荟玉8237、荟玉246作为优先主推品种,闽玉683、通玉201、宁单19号作为候选品种进行推广。In order to select excellent maize varieties suitable for planting in Mid-Zhejiang area,we analyzed the agronomic traits of 11 imported maize varieties by means of correlation analysis and principal component analysis,and comprehensively evaluated the adaptability of these varieties.The results showed that compared with the control Suyu 29,the introduced varieties had better agronomic characters,quality and disease resistance.The variation coefficients of 7 agronomic traits ranged from 7.31%to 13.82%,among which the variation coefficients of 100-grain weight,spike height and spike row number were larger.Plant height was significantly positively correlated with spike fresh weight(p<0.01),and was significantly positively correlated with spike height,spike row number and spike length(p<0.05).The cumulative contribution rate of the three principal components was 86.67%.Based on the yield,quality and disease resistance of fresh ears,Huiyu 8237 and Huiyu 246 were priority,followed by Minyu 683,Tongyu 201,and Ningdan 19.
