应用灰色关联度分析法,对12个超甜玉米杂交种9个主要农艺性状与鲜穗产量进行分析。结果表明:超甜玉米杂交种鲜穗产量与各性状的关联度大小顺序为吐丝期>穗行数>穗长>穗粗>双穗率>行粒数>株高>百粒重>着粒深度。为优质高产超甜玉米杂交种选育提供参考。
By using gray relational analysis method, 9 main agronomic traits and fresh ear yield of 12 super sweet corn hybrids were analyzed. The results showed that the order of the correlation between fresh ear production and traits of super sweet corn was silking stage> ear row> ear length> ear diameter> double ear rate> line number> plant height> 100 grain weight> Grain depth. Provide a reference for the breeding of high quality and high yield super sweet corn hybrids.
