摘要
以花生栽培品种04D893×79266杂交,经多代自交获得包含142个家系的F6∶7重组自交系群体为材料,分别在2011-2012年2个环境条件(E1和E2)下种植,对荚果和籽仁的6个产量相关性状进行遗传模型分析并进行其遗传参数的估算。结果表明,单果质量的遗传符合2对主基因遗传模型,主基因遗传率2年平均为45.97%;单仁质量的遗传符合3对主基因遗传模型,主基因遗传率平均为67.54%;果壳厚度的遗传符合3对主基因遗传模型,主基因遗传率平均为63.24%;果长的遗传均符合3对主基因遗传模型,主基因遗传率平均为81.14%;果宽的遗传符合2对主基因遗传模型,主基因遗传率平均为59.83%;单株生产力的遗传符合2对主基因遗传模型,主基因遗传率平均为21.76%。
A cross of 04 D893 and 79266 in cultivated peanut was made and then selfed to construct a F6∶7 RIL population which has 142 individuals .Genetic analysis was made by method of major gene plus polygene mixed in-heritance model based on the RIL population .The single pod weight was controlled by two major genes in two envi-ronments（E1 and E2）,the main gene heritability was 45.97%;The weight of per-kernel was controlled by three major genes,their heritability was about 67.54%;The thickness of pod shell was controlled by three major genes , their heritability was about 63 .24%;Length of pod shell was controlled by three major genes ,their heritability was about 81 .14%;Width of pod shell was controlled by two major genes , their heritability was about 59 .83%;Total pod weight per-plant was controlled by two major genes ,their heritability was lower ,about 21 .76%.The results pro-vided a valuable reference in selective breeding practices .
