ABSTRACT

Background: This study is a part of an ample research concerning the genetic history of Hucul horse breed. The genetic analysis studies are part of animal genetic resources Management because just start of them we elaborate the strategies for inbreeding management. The itself genetic relationship of a population is the average genetic relationship of all individuals between them, existing at a time. Therefore, this parameter can be described three components: the genetic relationship between stallions, between mother mares themselves and  the genetic relationship between stallions and mares. The last component is most important because of the average population inbreeding increases in successive generations. 
Methods: The research was carried out during 2012-2020. The material are represented by genealogical information from reproductive nucleus of Hucul breed from Lucina studfarm. The sample extracted from population was represented by seven sire stallions and seventy-three broodmares. The method are based on A matrix coefficients. All analysis were performed in the profile laboratories of Animal Sciences Faculties from Bucharest and Timisoara.
Result: Between individual average genetic relationship values of stallions with mares, is found significant differences, highlighted by the global test of homogeneity test (F = 4.891). These differences allow us to assert that, through stallions selection, is made a reproductive discrimination much more intense than in mares case. The average genetic relationship of the population was calculated at 0.1941±0.0053.
