Analysis of Genetic Diversity of the Higher and Lower Royal Jelly Producing Bee in China with Microsatellite Markers

Ji Ting, Yin Ling, Liu Min, Bao Wen-Bin and Chen Guo-Hong    

Abstract: Genetic diversity of Pinghu royal jelly bee (higher royal jelly producing bee) and Suwang No.1 bee (lower royal jelly producing bee) were evaluated with 23 microstaellite loci, the genetic variability within breeds and genetic differentiation between breeds were estimated, the results showed that in 23 microstaellite loci, 211 alleles were found, the number of alleles per locus ranged from 3-14, the average expected heterozygosity and PIC of all loci were 0.6894 and 0.6560, respectively. Mean numbers of alleles of Pinghu royal jelly bee and Suwang No.1 bee were 6.65 and 6.13, inbreeding index (FST), Reynolds' genetic distance and gene flow between two populations were 0.194, 0.2146 and 1.0447, respectively, these results indicated that the heterozygosity and the genetic diversity of 2 bee populations were very high.
