Abstract: Genetic map of sorghum×sudan grass(314AZKSD)were constructed based on AFLP and RAPD markers with F2:3 populations. The field experiments were designed with randomized blocks of 3 replications in 2 areas and involved 248 families of F2:3. Ten main agronomic characters (including yield)were tested. The quantitative trait loci (QTL)and gene effects of 10 characters were analyzed with composite interval mapping (CIM)based on the genetic sergeants analysis. The main results were as follows.

Key words: AFLP, RAPD, Genetic map, QTL, Agronomic character, Sorghum×Sudan grass

摘要： 本文以高丹草(So rghumSudan grass)(314A×ZKSD)的F2:3家系作为构图群体, 构建了高丹草AFLP和RAPD遗传图谱。将248个F2:3家系按随机区组重复3次的田间设计在两个试验点种植, 考察了包括产量在内的10个重要农艺性状。利用复合区间作图法分析10个性状的数量性状基因座位(QTL)以及基因效应值和基因作用方式, 并采用遗传分离分析法进行多世代联合分析, 主要结果如下。
