摘要
以14个甜、糯玉米为研究材料,对影响甜、糯玉米鲜穗产量的8个性状和影响糯玉米籽粒产量的10个性状进行灰色关联分析,结果表明:各主要数量性状对甜玉米鲜穗产量的关联度大小为:穗长>穗粗>采收日数>穗行数>穗位高>行粒数>秃尖>株高;对糯玉米鲜穗产量的关联度顺序为:穗位高>株高>行粒数>采收日数>穗粗>穗长>秃尖>穗行数;对糯玉米籽粒产量的关联度顺序为:千粒重>穗粗>株高>穗行数>穗位高>穗长>行粒数>出籽率>秃尖>生育期。
The correlativity between the various characters of 14 sweet and waxy corn varieties and yield was analysed by using the method of grey correlativity. The result shows the magnitude on effects of various characters in yield was respectively as follows:to the yield of fresheating sweet corn,ear length>ear thickness>harvesting day>rows per ear>ear high>kernels per row>bald>plant high; to the yield of fresheating waxy corn,ear high>plant high>kernels per row>harvesting day>ear thickness>ear length>bald>rows per ear; to the grain yield of waxy corn,weight per thousand seeds>ear thickness>plant high>rows per ear>ear high>ear length>kernels per ear>kernel production ability>bald>growth period.
