Thirty EST-SSR(simple sequence repeat) markers,developed by the authors were applied for identification of a new litchi germplasm 'Hongdenglong' by UPGMA cluster analysis of genetic relationship,and analysis on specific types of bands and polymorphism and molecular fingerprint with other 95 litchi germplasm.The results confirmed that the newly selected variety 'Hongdenglong' was identified as a new litchi germplasm and the possibility of being a crossing hybrid from the suspected germplasm was also excluded...
