本研究采用SNP3K芯片对亲本黄早四和14份黄改系材料进行遗传基础分析。结果表明:14个黄改系与黄早四的相似度比例在90.1%~98.0%之间。黄改系已达到纯合状态,可以认定黄改系是黄早四的近等基因系。14个黄改系在10条染色体上的相似度在88.3%~97.9%之间。黄改系在形成的过程中主要在染色体两端进行杂合,属于易变、敏感区域。 In this study, SNP3K chip was used to analyze the genetic basis of Huangzao-4 and 14 yellow lines. The results showed that the similarity of 14 yellow lines and Huangzao 4 was between 90.1% and 98.0%. Huang Department has reached a homozygous state, you can determine the yellow system is yellow near four isogenic lines. The similarity of 14 yellow lines on 10 chromosomes ranged from 88.3% to 97.9%. In the process of formation, yellow modification system is mainly heterozygous at both ends of the chromosome, belonging to the variable and sensitive area.
