Abstract

Cilj istraživanja je utvrditi čini li populacija svinje banijske šare zasebnu genetsku strukturu razlučivu od geografski i genetski bliskih populacija, pomoću multivarijatnih metoda i prostorne informacije. Prostornom analizom glavnih komponenti (sPCA), te geneland klasteriranjem obrađeni su georeferencirani mikrosatelitni genotipovi 86 jedinki četiri pasmine svinja (turopoljske, crne slavonske, banijske šare i njemačkog landrasa) u sustavu R pomoću adegenet i geneland paketa. Rezultati sPCA pokazuju: (i) da se očekivani utjecaj genotipa turopoljske svinje na banijsku šaru progresivno smanjuje u jugoistočnom smjeru; (ii) uzorci turopoljske svinje razdvajaju se od ostalih prvom globalnom osi; (iii) uzorci banijske šare grupiraju se u dvije skupine. Geneland analizom potvrđeni su rezultati sPCA i prepoznato je pet klastera te su izrađene karte. Banijska šara je razlučiva od ostalih analiziranih pasmina, te uzorci čine dvije genetske skupine.

Abstract (english)

The aim of the research was to determine if the Banija spotted pig population has genetic structure differentiated from geographically and genetically close populations, using multivariate methods in combination with the spatial GIS information. Spatial principal component analysis and Geneland clustering were used for the analysis of 86 georeferenced genotypes of four pig breeds (Turopolje, Black Slavonian, Banija spotted and German landrace) using the adegenet and geneland packages for R software. Results of sPCA show: (i) the expected genetic cline of Turopolje breed into Banija spotted pig; (ii) first global axis divides Turopolje samples from other breeds; (iii) Banija spotted samples form two groups. Geneland clustering confirmed sPCA results by recognizing five clusters shown on the maps. Banija spotted pig is genetically differentiated from the rest of analyzed genotypes and forms two groups.
