Abstract :
The present study aimed at assessing the genetic position of the Hungarian Gray population.
Hungarian Grey cattle kept at different farms in Hungary have been sampled (34 herds, n=3,187 in
the period of 2009-2011) to investigate their genetic relationship based on analysis of allelic variation
at eleven microsatellite
. The mean observed heterozygosities per herd were above a moderate
degree (0.60-0.80). Calculation of pairwise genetic distances and analysis of the history of herds
revealed that among the most closely related herds we can find those, which are the core of the
current Hungarian Gray population. The results of the population differentiation showed that all
Hungarian Gray herds were significantly different from each other. In most cases (22 herds) F
values were within a range of low degree of genetic differentiation (0.003-0.050), while the remaining
12 herds differed from the central population by F
values of 0.060-0.119. Principal coordinate
analysis, assignment tests and dendrograms all suggest that there are mainly two different groups
among Hungarian Grey herds. Structure analysis has yielded K=3 as the most probable number
of clusters. Based on the private allelic richness, genetic distance and F
values identified were
12 herds where more attention should be paid by the management to avoid genetic drift and to
preserve genetic diversity. The results presented could also contribute to the proper selection of
animals for further whole genome scan studies of Hungarian Grey.
