玉米籽粒锌、铁含量与籽粒性状的相关及QTL定位分析
Correlation Analysis and QTL Mapping for Kernel Traits and Zinc, Iron Content in Maize
摘要
Abstract
The F2:3 family group from inbred line 178 and Zheng 58 were used as material, QTL mapping and correlation analysis of Zn and Fe content of maize kernel,kernel structure,hundred kernel weight were demonstrated in two different places in this study. The results showed that the content of Zn was positively correlated with Fe content, the correlation coefficients were 0. 159,0. 395 respectively. The kernel depth and kernel thickness were significantly negative correlated with each other. The correlation coefficients were -0. 68 and -0. 252, respectively. The kernel depth and hundred kernel weight were highly significant positive correlated, whose correlation coefficient were 0. 445 and 0. 341 ,respectively. The kernel width and hundred kernel width were highly significant positive correlated with correlation coefficient of 0.448 and 0. 570, respectively. 21 QTLs for main kernel traits of F2:3 family group were identified in Baoding and Handan including 16 QTLs identified in Baoding,5 QTLs identified in Han-dan. Between markers umc 1097-umc1670 section on chromosome 5,Zn content and Fe content had a common QTL location section which explained 6. 40% - 12. 41% and 7. 23% - 18. 85% genetic variation respectively. These results indicated there were common QTLs for Zn and Fe content in kernel in this section.关键词
