Descriptors for Registration of Fish Germplasm. 1. Both Marker data, morpho – meristic characters data will be used as descriptors together or individually.
2. The distinct genetic stock will be considered for registration if there is sufficient evidence that allele/haplotype frequencies significantly differ from another neighboring subpopulation atleast at one locus. 3. The genetic stock thus considered distinct must be submitted with standard morpho-meristic data and production traits also, if claimed for the production value. 4. The genetic stocks differences based on only morpho-meristic characteristics will also be considered, if data is supported with sufficient sample size (>50) per location and done through use of standard methodologies & parameters.
5. The appropriate Performa, to derive information from applicant for registration of genetic stock (given above) will be used for production traits, if some genetic stock is claimed for superior production value wrt trait.
5. The desired information will include sample size (>50) per location; only co-dominant & mtDNA markers will be allowed; no. of markers (loci) used; Results to prove that pairs of loci did not suffer from linkage disequilibrium and are neutral; results to prove that the allele frequencies at locus that differ from the nearest neighbors examined with same set or parameters and other details of analysis.
