摘要
以感、抗螟虫高粱自交系ICSV745和PB15881 3杂交获得的252份F5重组自交系为试材,采用SSR分子标记,构建了包含10个连锁群、104个SSR分子标记组成的高粱连锁图谱。该图谱覆盖基因组长度1656cM,平均图距15.9cM。连锁群上有22.1%偏分离,偏分离标记在连锁群上聚集出现。
A molecular genetic map of sorghum was constructed with a 252 F5 recombinant inbred line(RIL)population from a cross of two sorghum lines ICSV745 and PB15881-3 by using SSR markers.ICSV745 is a spotted stem borer susceptible breeding line whereas PB15881-3 is resistant to spotted stem borer. The map consist of 10 linkage groups and include 104 genetic markers. The map covers 1 656 cM with an average genetic distance of 15.9 cM. A total of 22.1% distorted markers distributed in the map.
