黑糯玉米主要品质性状的遗传分析

Genetic Analysis of Major Quality Characters of Black Glutinous Maize

以国内外收集的8个黑糯玉米自交系为材料,采用不完全双列杂交法,分析黑糯玉米子粒主要品质性状的遗传规律。结果表明:脂肪和硒含量的遗传以非加性效应为主,蛋白质和维生素E含量的遗传中,加性、非加性效应共同起作用;F1与母本脂肪含量、维生素E含量均呈极显著正相关,F1脂肪含量与硒含量的遗传相关达正向显著水平。

With partial diallel cross, Eight black glutinous maize inbred lines which originated from inland or oversea were used in the experiment. Genetic parameter of major characters were appraised, genetic laws of seed quality characters were studied. The results indicated： Fat content and Se content were mainly controlled by the effects of non-additive gene; protein content and VE content were controlled by the effects of additive and non-additive gene. F1 had extremely significant positive correlation with fat content of female parent, so is it with VE content; F1 fat content had significant positive correlation with Se content.
