Abstract：In order to evaluate theirs genetic diversity and temporal trends, 200 accessions, including the core wheat(Triticum aestivum L.) parent Funo and its derivative varieties (lines), were analyzed using 29 informative markers selected from 304 SSR markers. A total of 197 alleles were detected and the alleles with frequency lower than 5% accounted for 14.21%. The scale of the number of alleles was from 3 to 15 with an average of 7.41 per SSR marker. The number of alleles declined trend among Funo and its derivative varieties (lines). The polymorphism information content (PIC) value varied from 0.5499 to 0.9082 with an average of 0.7763 and was high in the tested materials. In the three genomes of wheat, the average genetic richness were 7.14, 7.73, and 7.00 (Genome B＞A＞D), respectively, and the genetic diversity indices were 0.7687, 0.7763 and 0.7517 (Genome B＞A＞D), respectively. The genetic diversity of B genome was the most abundant. Among the seven homoeologous groups, the average genetic richness were group 6＞2=4＞1=3＞7＞5, and the genetic diversity indexes were group 2＞7＞6＞4＞1＞3＞5, and therefore group 5 possessed the lowest genetic diversity. Funo specific bands of SSR markers Xgwm268, Xgwm400, Xwmc398, Xwmc125, Xwmc817, Xgwm272 and Xgwm383 were with the higher inheritable rates among the tested materials, but their contribution ratio differed among the different genomes and chromosomes. The similarity coefficient of the 200 materials varied from 0.4162 to 0.9442 with an average of 0.6619. The ranges of similarity coefficient were becoming narrower and narrower from the first generation to the forth generation, and the genetic similarity coefficient of Funo's pedigree had the tendency of increasing with time slightly. UPGMA (unweighted pair group method with arithmetic mean) cluster analysis revealed that all the materials could be divided into five categories in the genetic similarity coefficient of 0.624, of which 180 (90.0%) species were clustered in the same class. The genetic basis of Funo derivative varieties(lines) was very narrow, and the genetic diversity was poor. The above results demonstrated that the genetic diversity and temporal trends of Funo and its derivative varieties (lines) implicated in the molecular level, and 7 SSR markers with the higher inheritable rates were detected, and thus this may useful to study the genetic basis of Funo
