| 摘 要： | 采用灰色关联度分析法,对杂交玉米产量比较试验中11个参试组合的产量与11个相关性状间的关联度进行了分析。结果表明:各性状对产量的影响顺序为:穗粗>出籽率>穗行数>行粒数>籽长>千粒重>株高>穗长>穗位高>茎粗>秃尖长。因而,在杂交玉米品种选育过程中,应当注重选择果穗比较粗、出籽率高、穗行数较多、行粒数比较多、籽粒比较长的组合,对于秃尖长、茎粗、穗位高等可放宽要求。

| Abstract: | The grey correlated degree analysis was used to investigate the relationship between yield and 11 related traits of 11 hybrid maize combinations tested in the yield comparative test.The results showed that the 11 related traits had different influence on the yield,they could be arranged as follows: ear diameter > rate of bearing kernel > kernel row of ear > kernels per row > kernel length > 1000-kernel weight > plant height > ear length > height of ear position > stem diameter > bald tip length.Therefore,in... |
