浙江省无花果种质资源亲缘关系的SRAP 分析评价

SRAP Analysis on Genetic Relationship of Germplasm Resources of Ficus carica in Zhejiang Province

  • 摘要: 利用SRAP 分子标记技术,结合物候期对从美国、英国、意大利、法国、中国等地收集的适合浙江省种植的15 个无花果品种的亲缘关系进行分析。结果表明,不同品种物候期存在不同程度差异,萌动期均为3 月中下旬;展叶期在4 月中下旬;座果期基本为5 月初;果实成熟期6 月底、7 月中旬、7 月底,8 月中旬、9 月均有;筛选出SRAP 引物34 个,扩增出204 条多态性条带,多态率为62.25%,表明无花果种质资源的种内变异较为丰富;15 个品种间的遗传相似系数在0.691 ~ 0.922,其中‘波姬红’与‘玛斯义陶芬’,‘美丽亚’与‘金傲芬’之间的遗传相似系数最大,为0.922,亲缘关系最近;‘红矮生’和‘日本紫果’遗传相似系数最小,为0.691。聚类分析表明在遗传距离为0.735 处,不同品种分为两个大类群,其中‘红矮生’单独聚为一类,其余品种聚为一类。物候期观察表明,同一生长环境下,物候期与品种亲缘关系相关。

     

    Abstract: Fifteen culitvars of Ficus carica from the United States, the United Kingdom, Italy, France and China were planted in Wuyi, Zhejiangprovince in 2015, leaves were collected in March 2016 for evaluation of genetic relationships among these cultivars by SRAP markers andobservations on phenological periods. The results showed that there were differences in phenological period among 15 germplasm resources, withsprouting period from middle to late March, leaf expansion from middle to late April, fruit setting at early May, and fruit mature from late June to theearly September. 34 SRAP primers were selected, 204 polymorphic bands were obtained by PCR with the polymorphic rate of 62.25%, indicatingabundant intraspecific variation. The genetic similarity coefficient among 15 cultivars was 0.691-0.922, with the maximal coefficient of 0.922 of‘A132’ and ‘Masui Dauphine’, and the minimal of 0.691 of ‘Violette Solise’ and ‘Hongaisheng’. Cluster analysis showed that tested germplasm couldbe divided into two groups at genetic distance of 0.735. ‘Hongaisheng’ was clustered alone, the others were clustered into one group. Observation onphenological period of tested cultivars planted in the same location showed that their phenology had relation with their provenances..
