摘要:
为进一步探究玉米抽雄期茎秆木质素含量的遗传基础，以普通玉米自交系B73 (强抗倒性)为母本、以普通玉米自交系辐673(弱抗倒性)为父本构建的重组自交系群体及亲本为试验材料，采用主基因+多基因联合分离分析模型，对玉米抽雄期木质素含量进行遗传分析。结果表明：玉米抽雄期茎秆木质素含量遗传符合加性-上位性+多基因遗传模型，主基因遗传率为41.32%，多基因遗传率为38.79%，多基因效应影响显著。因此，在抗倒伏玉米品种的选育过程中要同时注意基因间的加性效应和基因间的互作效应，也不能忽视微效多基因的累加效应。
Abstract:
In order to further explore the genetic basis of lignin content in maize stem at tasseling stage,the recombinant inbred line population and parents constructed with common maize inbred line B73(strong lodging resistance) as female parent and common maize inbred line Fu 673(weak lodging resistance) as male parent were used as experimental materials.The combined separation analysis model of major gene and polygene was used, and genetic analysis of lignin content in maize at heading stage was carried out.The results showed that the inheritance of stem lignin content in heading stage of maize accorded with the additive epistasis + polygenic genetic model.The major gene heritability was 41.32%,and the polygenic heritability was 38.79%.Therefore,in the breeding process of lodging resistant maize varieties,we should pay attention to the additive effect and interaction effect between genes,and the cumulative effect of micro effect multi genes can not be ignored.
