| 摘 要： | 利用相关分析和通径分析的方法，对早熟夏玉米品种资料进行了分析。认为筛选早熟、丰产、适应性广泛的玉米杂交种，应重点对千粒重和穗行数进行正向直接选择，对穗位和秃尖进行负向直接选择，同时要协调好各性状间的遗传相关关系。对其他性状如出籽率、穗长和株高宜进行间接选择，选择不宜过严。

| Abstract: | The regional test data of early-maturing summer maize in Hebei Province were analyzed by using the method of correlation and path analysis.The results showed that the positive immediate selection should be carried out for thousand-grain weight and head progeny row in breeding of maize hybrid species with characters of early-maturing,high yield and wide adaptability.The negative immediate selection should be carried out for bald head and spike locality.Meanwhile,the genetic relationship between characters should be coordinated well.Other characters such as the rate of seed,length of ear and height of plant should not be strict. |
