Summary

The present study is a first step of a global project aiming at the estimation of the genetic distances and relationships among buffalo breeds and sub-populations and the investigation of the production potential and adaptability of different buffalo genotypes in various environments.

Genetic diversity of Italian and Greek buffalo populations was estimated on the basis of allele frequencies at nine polymorphic microsatellite loci: CSSM43, CSSM38, DRB3, D21S4, CYP21, CSSM47, CSSM60, CSSM36 and CSSM33. The number of detected alleles per locus varied from two (D21S4) to thirteen (CSSM47). Allele frequency distribution was similar in the two populations, which have the same alleles at the highest frequency at all loci, except loci CSSM47 and CSSM60. Average gene diversity over all loci was 0.60. Across-loci average gene diversity increased with the number of alleles. Observed average heterozygosity was 0.167 and 0.177 in the Italian and Greek populations, respectively. The degree of differentiation between Italian and Greek buffalo was moderate and estimated at 0.021 ± 0.009.

Resumen

El presente estudio representa un primer paso dentro de un proyecto global orientado a la estimación de las distancias genéticas y relaciones entre las razas de búfalos y las sub poblaciones y la investigación sobre la producción potencial y la adaptabilidad de los distintos genotipos de búfalos en condiciones ambientales diversas.

La diversidad genética de las poblaciones italianas y griegas de búfalos fue estimada en base a las frecuencias de alelos en nuevo loci microsatélites polimórficos: CSSM43, CSSM38, DRB3, D21S4, CYP21, CSSM47, CSSM60, CSSM36 y CSSM33. El número de alelos detectados por locus varió de dos (D21S4) a trece (CSSM47). La distribución de la frecuencia de los alelos fue similar en las dos poblaciones, que poseen los mismos alelos en la frecuencia más alta en todos los loci, excepto los loci CSSM47 y CSSM60.

La media de diversidad de genes en todos los loci fue de 0,60. Entre los loci la media de diversidad de genes aumentó con el número de alelos. La media observada de heterocigosidad fue de 0,167 y 0,177, en las poblaciones italianas y griegas respecitvamente. El nivel de diferenciación entre el búfalo italiano y griego fue estimado en 0,021±0,009.
