【摘要】 应用灰色理论关联度分析法,通过对夏玉米10个单交种的7个数量性状与子粒产量进行分析。结果表明:玉米杂交种的产量与各产量性状的关联度大小顺序为:叶数>行粒数>株高>穗长>百粒重>穗行数。目的为高产优质玉米杂交种的选育提供科学依据。更多还原

【Abstract】 The grey related degree analysis was employed to investigate the relationship yield between seven main quantitative characters of 10 maize hybrids was involved. The result showed an order about the grey related degree from large to small: leaf num>kernels per row>plant height>ear length>100 seeds weight>kernel rows. Aim to offer reference for breeding corn hybrid with good quality and high-yield.更多还原
