Istraživanje je provedeno na introduciranim sortama šljive: Top Five, Top Star, Top Gigant, Haganta, Jojo, Elena, Top 2000 i Top Hit. Analizirane su pomološke (širina, debljina i visina ploda, masa ploda i masa koštice, dužina peteljke te randman ploda) i kemijske osobine ploda (suha tvar, ukupna kiselost,ukupni fenoli), te boja ploda. Dobiveni rezultati pokazali su značajne razlike istraživanih svojstava između sorata u pokusu. Prema istraživanim svojstvima i roku dozrijevanja kao zanimljive za proizvodne voćnjake ističu se: Top Star, Haganta, Jojo i Top Hit. Boja kožice ploda nije relevantan pokazatelj dozrelosti ploda, te se bez analize organoleptičkih značajki, sadržaja topljive suhe tvari i kiselina, ne može pouzdano koristiti u svrhu određivanja roka berbe., The research was conducted on the introduced plum cultivars: Top Five, Top Star, Top Gigant, Haganta, Jojo, Elena, Top 2000 and Top Hit. The quality of the fruit was analyzed by pomological parameters (fruit width, thickness and length, fruit weight and seed weight, stem length and rendiment of fruit) and chemical analysis (total soluble solids, titrable acidity and total phenols) and fruit skin colour. The results showed significant differences between the varieties in the traits. According to the investigated properties and maturity tame interesting for orchard productions are: Top Star, Haganta, Jojo and the Top Hit. The colour of fruit skin is not a relevant indicator of fruit maturity, and without analysis organoleptic characteristics, of soluble solids and acids content, its can not be reliably used to determine harvest time.
