本研究以元江普通野生稻与优良栽培稻亲本特青配制的野生稻染色体片段代换系为材料,在幼苗生长阶段,利用室内、室外株高、干重抑制率的表型数据检测与耐铝相关的QTL,分别检测到11、18、14和5个与耐铝相关的QTL,分布于不同的染色体上,室内、室外株高抑制率的表型数据检测结果表明,位于第8染色体RM38附近和第12染色体RM277附近贡献率较大,分别为12%和11%,分析是主效QTL。室内、室外干重抑制率的表型数据检测到的最大QTL的贡献率分别只有9%和8%,未检测到主效QTL。重复检测到的QTL分布于第7、8、9、11和12染色体上。第8染色体上有2个QTL,其中RM310附近的QTL被三次重复检测到,其余的被检测到二次,分析这些QTL是稳定的QTL。
In this study, we used the substitutions of the chromosome segment substitution lines of wild rice (Oryza sativa L.) cultivated in Yuanjiang common wild rice and elite cultivated rice Teqing as material, and detected the phenotypic data of indoor and outdoor plant height and dry weight inhibition ratio Related QTLs detected 11, 18, 14, and 5 QTLs related to aluminum tolerance on different chromosomes. The results of phenotypic data of indoor and outdoor plant height inhibition showed that the QTLs located around RM38 on chromosome 8 And RM277 on chromosome 12, the contribution rates were higher, accounting for 12% and 11%, respectively. Analysis was the major QTL. The maximum QTLs detected by the phenotypic data of indoor and outdoor dry weight inhibition rates were only 9% and 8% respectively, and no major QTLs were detected. QTLs detected repeatedly were distributed on chromosomes 7,8,9,11 and 12. There were 2 QTLs on chromosome 8, of which QTLs around RM310 were detected in triplicate and the rest were detected twice, and these QTLs were analyzed as stable QTLs.
