摘　　要：以80份加拿大玉米群体杂交选系为材料,通过田间农艺性状鉴定结果表明,供试自交系存在丰富的表型遗传变异。主成分分析结果筛选到12份综合性状表现优良的杂交选系,SW1184(B73×EP8)、SW1084(Mo17×EP3)、SW1081(Mo17×EP3)、SW1195(掖478×EP18)和SW1137(龙抗11×EP21)等选系生育期较早,株高和穗位高适中,花期间隔较短,单株产量和百粒重较高,出籽率较高,其他性状综合表现较好。SW1184(B73×EP8)各性状表现均优良,在育种中可优先利用。The 80 selected lines originated from Canada population were materials, the result showed the pheno- type variance was rich by field agronomic character identification, the 12 selected lines which contained SWl184 （B73 ×E P8）, SW1084（Mo17 × E P3）, SW1081 （Mo17 × EP3）, SW1195 （Ye478 × EP18） and SW1137 （Longkangl 1 x EP21） were superior to other lines by principal components analysis. The performance of selected lines was early-ma- turing, moderate height, shorter flowering interval, higher yield, high 100-seed weight and seed rate, and SW1184 was the best one. It could be priority used in breeding.
