鲜食糯玉米主要数量性状对鲜穗产量的作用及效应分析

Efficient Analysis of Main Quantitative Characters and Fresh-eaten Glutinous Maize Yield

对鲜食糯玉米的11个主要数量性状与鲜穗产量进行相关和通径分析,为选育鲜食糯玉米高产品种的性状选择提供理论依据;各性状中与产量的相关系数和直接通径系数最大的性状为穗粗、穗长、株高和行粒数,应高度重视对这些性状的选择,选择较好的表现型。同时要保证一定的穗位高和粒深,对生育期、穗行数、秃尖长、出籽率和百粒重可适当放宽选择尺度。

Correlation and path analysis of fresh ear yield and 11 major quantitative characters were made in fresh-eaten glutinous maize,which can provide academic basis for high yield fresh-eaten glutinous maize variety-breeding.Among those characters,the correlation and path coefficients of ear diameter,ear length,plant height and kernels per row were more importance to yield,so we must pay attention to these characters,try our best to choose their good phenotypes for appropriate ear height and kernel depth,but for others.
