In this paper result of external characteristics of brooding eggs originating from two breeds are presented, New-Hampshire and Sombor Crested, bread in semi extensive breeding system. Research was conducted on 30 eggs from each analyzed breed, the parent flocks. Aim of the research was to examine the influence of genotype on basic egg quality parameters such as, weight, length, width and shape index for the brood as well as specifying the possibilities for preserving and enhancing the productive and reproductive traits of autochthonous chicken breeds compared to imported breeds. Obtained results point at the fact that Sombor Crested as autochthonous breed regarding the weight of eggs has similar results as New-Hampshire, as difference 1, 04 g has not shown any statistically significant difference (P is greater than 0.05). However, the obtained difference in length (0,48 cm) and width of the eggs (0,16 cm) were bigger at New-Hampshire breed and statistically significant (P is less than 0.001), while at shape index difference of 1,00% was higher and statistically significant (P is less than 0.001) at Sombor Crested. Results of conducted research shows that it is needed to pay more attention in brooding eggs quaity, specially for autochthonous chicken breeds, then towards the breeding direction all with the goal to better their productive and reproductive traits. Moreover, by doing that we will preserve the autochthonous genetic potential of different species, breeds and lineages of chicken.
