Sažetak
Petogodišnjim istraživanjem su bila obuhvaćena dva genotipa nazimica švedski landras i melezi F1 generacije ŠLxVJ. Od ukupnog broja (n=3600) istraživanjem je obuhvaćeno 1709 grla genotipa ŠL i 1891 grla genotipa ŠLxVJ. Merenje debljine leđne slanine i dubine musculus longissimus dorsi (MLD) i procena mesnatosti je obavljeno ultrazvučnim aparatom Piglog 105. Za pokazatelje mesnatosti utvrđeni su srednji heritabiliteti za SL1 h2=0,461, a visoki za SL2 h2=0,639, i za mesnatost h2=0,633. Nizak heritabilitet utvrđen je za dubinu MLD-a (h2=0,105), životni dnevni prirast (h2=0,110) i za uzrast (h2=0,103). Utvrđene fenotipske korelacije između debljine slanine SL1 i SL2 su jake (rp=0,638); između debljine slanine i mesnatosti korelacije su vrlo jake (rp=-0,880 do -0,895), dok su između debljine slanine i MLD-a jako slabe i negativne (rg=-0,103 do -0,216). Genetske korelacije su jače od fenotipskih, tako da je između debljine slanine korelacija potpuna (rg=0,930), kao i između debljine slanine i mesnatosti (rg=-0,979 do -0,982), dok je korelacija jaka i negativna između debljine slanine i MLD-a (rg=-0,627 do -0,653).
