摘要
应用灰色关联度分析法,以2010年四川省鲜食甜玉米区试14个组合的10个农艺性状与鲜穗产量进行了分析。结果表明,甜玉米农艺性状与鲜穗产量关联度的大小依次为穗行数>穗长>行粒数>穗粗>出苗-采收>穗位高>株高>百粒重>秃尖>出籽率,穗行数是影响甜玉米鲜穗产量的主要因素,其次是穗长、行粒数,而出籽率对产量影响较小。
10 agronomic characters and fresh ear yield of 14 combinations in fresh-eat sweet corn region test of Sichuan in 2010 were analyzed with grey relation grade analysis.The results showed： relational degree order of agronomic characters and fresh corn yield were as follows： row per earear lengthkernel per rowear diameterear heightplant height100-kernel weightbald tip lengthkernel rate.Row per ear was the main factor affecting fresh yield of sweet corn,and the second was ear length and kernel per row,but the kernel rate had less effect on yield.
