摘　　要：根据东北玉米主产区的分布情况,将10个玉米组合分别布点在沈阳、铁岭、辽阳、锦州、大石桥五地,进行组合间和品种间的产量比较试验。结果表明:Z4,Z3株高分别位列第一、第三,Z4,Z3穗位高度位列第一、第二,Z4,Z3倒伏倒折率位列第一、第二,说明株高、穗位高低与倒伏倒折率有必然联系;Z5在各地丰产性、适应性、抗逆性都比较好。According to the distribution of main corn producing areas in northeast China,10 maize combinations were distributed in 5 areas,which were Shenyang,Tieling,Liaoyang,Jinzhou and Dashiqiao.The results showed that:Plant height of Z4 and Z3 were ranked first and third respectively,ear height of Z4 and Z3were ranked first and second,and lodging inversion rate of Z4 and Z3 were ranked first and second,indicating that plant height and ear height were correlated with lodging inversion rate;Z5 has good fertility,adaptability and stress resistance in various places.
