摘　　要：以玉米高密度遗传连锁图谱IBM2 2008 Neighbors为参考图谱,收集来自不同磷素条件下定位的307个玉米产量构成因子的数量性状位点(quantitative trait locus,QTL),利用Bio Mercator 2.1软件在10条染色体上发掘出36个不同磷素条件下产量构成因子"一致性"QTL(MQTL)区间。图距范围在0.73~7.44 c M之间。通过MQTL两端标记在玉米物理图谱Ref Gen_v2上的位置,将MQTL进行物理图谱定位。MQTL在物理图谱上的图距范围在0.5~10.6 Mb之间。结果表明MQTL位点为今后发掘玉米耐低磷产量构成因子的候选基因提供了基础,为深入理解磷素产量构成因子遗传控制机制和分子设计育种提供科学依据。High density g enetic linkage map IBM2 2008 Neighbors of maize were used as reference map, we collected 307 quantitative trait loci（quantitative trait locus, QTL） involved yield components under different phosphorous conditions. 36 consistency QTLs related yield component were detected under different phosphorus conditions among 10 chromosomes of maize by Bio Mercator2.1 software, the interval distance of each MQTL were ranged from 0.73 to 7.44 c M. According the makers position of MQTL in the physical map of Ref Gen_v2,the physical position was found, and the physical distance of each MQTLranged from 0.5 to 10.6 Mb. The results showed that MQTLs offered a base to explore the candidate genes for the yield components under low phosphorus condition in the future, and it can offer a scientific basis for molecular design breeding and further understand the genetic mechanism of yield components in maize.
