Studies on segregation of RAPD markers in a F1 hybrid family and parents of Haliotis discus hannai Ino

摘要: 应用RAPD标记技术对皱纹盘鲍杂交家系JC的双亲及3个F1个体进行了分析,对JC家系在皱纹盘鲍遗传连锁图谱构建中的应用前景进行了初步评估,并分析了RAPD分子标记在JC家系F1代中的分离方式及该家系的1对亲本及其子代个体的遗传结构.7条随机引物共扩增出41个分子标记,其中24个为多态性,占总数的58.5%;有14个分离标记可用于遗传连锁作图,有7个符合孟德尔独立分配定律,占总数的17.1%.2个标记与子代个体大小有一定的相关性,但其连锁关系仍有待于进一步研究.父母本之间的遗传距离为0.384 4,父本与子代间的距离为0.137 2,母本与子代间的距离为0.127 3;父本提供的分离标记在子代中的显性频率为0.47,母本为0.55.双亲之间的遗传距离较远,杂交产生的JC-F1群体具有较高的杂合度(0.201 6),该结果初步表明皱纹盘鲍杂交家系JC的子1代即可作为作图群体应用于皱纹盘鲍的连锁图谱构建.Abstract: The genetic structure and segregation of molecular markers in a F1 hybrid family of Pacific abalone(Haliotis discus hannai Ino)were studied using random amplified polymorphic DNA(RAPD)technology.This family's usefulness in linkage mapping of abalones was assessed.Seven primers yielded a total of 4.markers,of which 24 (58.5%)were polymorphic in this family,14 were informative and could be used for linkage mapping,and 7 (17.1%)markers were segregated in the expected Mendelian ratio which is very low compared with other species. Two markers show some association with JC-F1's phenotypes,and this relationship needs further study.The genetic distances between two parents,father and progeny,mother and progeny are 0.384 4,0.137 2,0.127 3 respectively.The frequency in JC-F1 population of RAPD markers from father and mother are 0.824 and 0.841, which are almost the same.High genetic distance between parents and high heterozygosity(0.2016)in JC-F1 population is also confirmd the feasibility of linkage mapping using these parents and progenies.
