| 摘 要： | 采用灰色关联度分析法,对2018年西南玉米区试11个新组合的12个主要农艺性状与产量的关系进行分析与评价。结果表明:11个玉米新组合主要农艺性状与产量的关联度大小依次为:百粒重>生育期>秃尖长>穗位高>穗粗>穗行数>空秆率>出籽率>株高>穗长>倒折率>倒伏率,百粒重、生育期和秃尖长对产量的影响排在前3位,而倒折率和倒伏率对产量的影响相对较小。

| Abstract: | Grey correlation degree analysis method was applied on 12 main agronomic traits and yield of11 maize varieties in 2018.The results showed that ranked list of grey correlation degree of agronomic traits and yield was,100 kernel weight>growth period>bald tip length>cornjob height>diameter of ear>kernel row number>empty stalk rate>rate of bearing kernel>height>ear length>folding rate>lodging rate.100 kernel weight,growth period and bald tip length were the main factors to effect the yield of maize,folding rate and lodging rate have less effect on yield of maize relatively. |
