Abstract

Abstract: A doubled haploid population derived from anther culture of Zhaiyeqing 8 / Jingxi 17 F₁, a typical indica and japonica hybrid, was used to detect root vitality by using TTC method at heading stage. Based on the constructed molecular linkage map, a QTL for root vitality was detected between RG449 and RG809 on chromosome 4 by using Mapmaker/QTL. Single gene effect and interaction QTLs were identified and tested by Epistat software. A single gene near RG809, two conditional interactions and four coadaptive interactions were identified for root vitality. These loci were on chromosome 1, 2, 4, 7, 8, 9 and 11.

Key words: rice, root, vitality, quantitative trait locus, epistasis

摘要： 以典型籼粳交(窄叶青8号/京系17) F1代花培加倍的DH群体为材料，在抽穗期用TTC法考察根系活力。利用已构建的分子连锁图谱，采用区间作图法对根系活力进行QTL分析，在第4染色体的RG449和RG809之间检测到一个QTL。用Epistat软件分析影响根系活力的单个位点和位点间的互作，结果在RG809附近检测到一个单基因，并检测到2个条件型互作和4对互适型互作，这些位点分布在第1、2、4、7、8、9和11染色体上。
