摘　　要：以枇杷‘早钟6号’和‘贵妃’杂交的56株 F1代群体为试材，应用Join-Map4．0作图软件初步构建含19个连锁群，94个遗传标记（23个 SSR 标记、28个ISSR 标记、42个 SRAP 标记和1个果肉颜色性状标记）的枇杷遗传连锁图谱。该图谱覆盖基因组849．0cM，连锁群平均长度为44．7cM，平均图距为9．1cM。每个连锁群包含2～16个标记，平均为4．9个标记。枇杷果肉颜色性状标记定位在第5连锁群上的S33-250和 UCB842-1000标记之间。A genetic linkage map for loquat was established based on 5 6 F1 population derived from the cross betweenZao Zhong No.6 and Gui Fei loquats using JoinMap 4.0 software.The map consisted of 1 9 linkage groups including94 genetic markers （i .e.,2 3 SSR markers,28 ISSR markers,42 SRAP markers and 1 flesh color GRYS trait）.The map covered 849.0 cM of the genome.The average length of the genetic linkage group was 44.7 cM,and theaverage distance between the adj acent loci was 9.1 cM.Each group contained 2 to 1 6 loci,and 4.9 markers pergroup.The marker linked to the flesh color of the fruits was located in between S3 3-2 50 and UCB842 - 1 000 inGroup 5 .
