Abstract:

No information is available on genetic characteristics of Indian Muscovy duck. Blood samples were collected from 52 Muscovy ducks from Manipur, Assam and West Bengal. DNA was isolated and data generated on 24 microsatellite loci. Population demographic estimations were made using various qualitative as well as quantitative tests of severe reduction in effective population size and population expansions. There has been no severe reduction in the population of Muscovy ducks as revealed by genetic bottleneck studies. The population of Cairina moschata has undergone expansions as revealed by k and g tests. The gene diversity of Indian domestic ducks is quite high with mean number of alleles per locus as 11.46. The mean effective number of alleles was 5.02. The mean heterozygosity was found to be 0.54 while the expected heterozygosity was 0.72. This along with the statistically significant FIS value (0.25), point towards the existence of population structure due to local inbreeding in Muscovy duck population. The Muscovy ducks in India need to be treated separately from Anas platyrhyncos and separate breeding and conservation strategies shall be needed
