| 摘 要： | 对鲁南地区种植的18个玉米品种的产量与9项主要农艺性状作灰色关联度分析,结果显示:主要农艺性状对玉米产量的关联度大小为:出籽率>百粒重>行粒数>穗行数>穗长>穗粗>穗位>株高>秃尖,其中,对玉米产量影响较大的性状为出籽率(0.9412)、百粒重(0.9309)、行粒数(0.9284)、穗行数(0.9165)、穗长(0.9147)、穗粗(0.9143);其次为穗位(0.9039)、株高(0.9003);秃尖(0.5359)与玉米产量的相关性最小。

| Abstract: | Based on the gray correlation analysis between the yield and 9 major agronomic traits of 18 maize varieties mainly grown in Lunan region,the correlation degree of main agronomic traits to maize yield is as follows:seed yield>100-grain weight>row number>row number>ear length>ear diameter>ear position>plant height>bald tip.Among them,the correlation degree of main agronomic traits to maize yield is as follows.The most influential traits were seed yield(0.9412),100-grain weight(0.9309),row number(0.9284),row number per ear(0.9165),ear length(0.9147),ear diameter(0.9143),followed by ear position(0.9039),plant height(0.9003),bare tip(0.5359) and maize yield. |
