| 英文摘要 | An agronomic gene pool of wheat (triticum aestivum l.) was constructed through recurrent selection. in present research, 24 wheat ssr markers determining 25 loci on 14 different chromosomes were used to evaluate the gene pool. thirty parents used as original materials in recurrent selection were also assessed. in total, 115 alleles were detected in gene pool with an average of 4.6, ranging from 2 to 9 alleles per locus. statistical test showed that genetic diversities had no significant difference between the gene pool and the 30 parents. principle coordinates analysis revealed that the individuals of the gene pool were mainly divided into three groups, which was consistent with the result of cluster analysis based on genetic distance matrix of the gene pool. cluster analysis was carried out based on euclidian distance calculated upon five morphological trait values and the results showed that most individuals were in a group while the others scattered. correlation analysis of genetic distance matrix and euclidian distance matrix showed no significant correlation between two matrices. the results suggest that the gene pool is improved after several cycles of selection, while genetic variation is still maintained. therefore, the gene pool is suitable for further breeding program. |
