| 摘 要： | 以LX00-6×E28的278个F2:3家系为作图群体,通过SSR标记利用MAPMAKER/EXP3.0和Mapdraw 2.0构建遗传连锁图谱.该连锁图覆盖玉米基因组1 508.1 cM,包含124个标记,相邻两标记的平均距离为12.2 cM.利用QTLMaper2.5软件,结合主要品质性状的检测结果,运用复合区间作图法,以LOD=2.0对玉米主要品质性状进行全基因组QTLs扫描,检测到两个与淀粉含量相关的QTL位点,分别位于第1、8条染色体上,表现为部分显性效应和加性效应,并在第1条染色体上检测到1个与油分含量相关的位点,表现为加性效应.

| Abstract: | Two hundred and seventy-eight of F2:3 individuals derived from the cross between inbred lines LX00-6 and E28 were used for developing the mapping population. A maize genetic linkage map with simple sequence repeat markers had been established using MAPMAKER/EXP3.0 and Mapdraw 2.0. The genetic linkage map with the genetic distance of 1 508.1 cM(centimorgan) and on average 12.2 cM every marker contains 124 markers. Using QTLMaper2.5, combined with the detection results of main quality traits in LOD=2.0, QTLs of main quality characters were scanned on the whole genome using composite interval mapping method. Two QTLs associated with starch content were detected, respectively on chromosome 1 and chromosome 8, showing partial dominance effect and additive effect. And one QTL associated with oil content was detected on chromosome 1, showing additive effect. |
