摘    要:本试验以9个子粒品质差异较大、遗传背景不同的爆裂玉米优良自交系为材料,就爆裂玉米的产量、膨胀倍数与主要数量性状的相关性进行通径分析。结果表明,爆裂玉米产量与主要数量性状的相关系数大小依次为:行粒数穗长穗粗百粒重株高茎粗出子率穗行数穗位高秃尖长淀粉含量;膨胀倍数与主要数量性状的相关系数大小依次为:膨化体积爆花率淀粉含量行粒数穗位高穗长茎粗小区产量株高穗行数出子率秃尖长百粒重穗粗。

关 键 词:爆裂玉米  数量性状  产量  膨胀倍数  通径分析

Abstract:Using fine inbred lines of popcorn as a material,which grain quality and genetic background are very different,correlation of their yield,popcorn inflation multiple and the with main quantity characteristics were path analyzed in the paper.The results showed that the correlation coefficient between the yield of popcorn and the main quantity characteristics were in following sequence: number of seeds per row>ear length>ear thickness>hundred grains weight>plant height>stem thickness>seed rate>number of lines ...
Keywords:Popcorn  Quantity character  Yield  Inflationary multiple  Path analysis
