摘要: 以杏扁品种‘龙王帽’授粉‘优一’获得98个F1代单株为作图群体,采用SRAP和SSR标记进行连锁图谱的构建。采用Join Map 4.0软件进行连锁分析,分别构建了‘龙王帽’和‘优一’的分子连锁框架图,共获得132个SRAP标记和17个SSR标记。其中父本遗传图谱涉及8个连锁群,包含53个SRAP标记和9个SSR标记,图谱总长为694.8 cM,标记间平均图距为11.21 cM,平均每个连锁群上有7.75个标记位点,连锁群平均长度为86.85 cM;母本遗传图谱涉及8个连锁群,包含79个SRAP标记和8个SSR标记,图谱总长为924.8 cM,标记间平均图距为10.63 cM,平均每个连锁群上有10.87个标记位点,连锁群平均长度为115.6 cM。

Abstract: Sequence-related amplified polymorphism(SRAP)and simple sequence repeats(SSR)were used to construct draft linkage maps using F1 population(98 individual plants)derived from a cross between Armeniaca vulgaris×A. sibirica “Longwangmao”and “Youyi’”. The molecular linkage maps of both “Longwangmao” and “Youyi” were constructed respectively using Join Map 4.0 software for the linkage analysis. Totally 132 SRAP and 17 SSR markers were obtained,The male map included 8 linkage groups with 53 SRAP and 9 SSR markers covering a total length of 694.8 centimorgans(cM)with an average of 86.58 cM;averagely there were 7.75 markers for each group and the average genetic distance between 2 markers was 11.21 cM. The female map included 8 linkage groups with 79 SRAP and 8 SSR markers and covered a total length of 924.8 cM with an average of 115.6 cM;there were average of 10.87 markers for each group and the average genetic distance between 2 markers was 10.63 cM.
