Abstract EN
In-depth information on sugarcane germplasm is the basis for its conservation and utilization.
Data on sugarcane molecular markers are limited for the Chinese sugarcane germplasm collections.
In the present study, 20 start codon targeted (SCoT) marker primers were designed to assess the genetic diversity among 107 sugarcane accessions within a local sugarcane germplasm collection.
These primers amplified 176 DNA fragments, of which 163 were polymorphic (92.85%).
Polymorphic information content (PIC) values ranged from 0.783 to 0.907 with a mean of 0.861.
Unweighted pair group method of arithmetic averages (UPGMA) cluster analysis of the SCoT marker data divided the 107 sugarcane accessions into six clusters at 0.674 genetic similarity coefficient level.
Relatively abundant genetic diversity was observed among ROC22, ROC16, and ROC10, which occupied about 80% of the total sugarcane acreage in China, indicating their potential breeding value on Mainland China.
Principal component analysis (PCA) partitioned the 107 sugarcane accessions into two major groups, the Domestic Group and the Foreign Introduction Group.
Each group was further divided based on institutions, where the sugarcane accessions were originally developed.
The knowledge of genetic diversity among the local sugarcane germplasm provided foundation data for managing sugarcane germplasm, including construction of a core collection and regional variety distribution and subrogation.
