| Abstract: |
| Twelve…microsatellite…DNA…markers…were…used…to…assess…the…genetic…diversity…of…giant…freshwater…prawn…
Macrobrachium rosenbergii of Guangxi…population…and…Guangdong…population…and…to…guide…the…selective…breeding…work.…
The…results…showed…that， 12…microsatellite…loci…in…the…amplification…products…of…two…M. rosenbergii…groups…were…all…
polymorphic， a…total…of…71…alleles…were…amplified， and…the…average…number…of…alleles…per…locus…was…5.92.…The…average…
effective…number…of…alleles， observed…heterozygosity， expected…heterozygosity， and…polymorphism…information…content…of…
Guangxi…population…were…3.9183， 0.9505， 0.7376， 0.6558， respectively， while…those…indexes…of…Guangdong…population…
were…4.4374， 0.9413， 0.7609， 0.6834， respectively， which…had…higher…genetic…diversity…than…Guangxi…population.…
Results…demonstrated…that…the…two…populations…of M. rosenbergii…both…had…high…genetic…diversity， which…had…great…potential…
for…the…selective…breeding…of…M. rosenbergii. |
