A summer-fruiting, highly vigorous cultivar. It produces numerous light-colored canes. Primocanes are strong and slightly bent in mid-section, bearing abundant secondary buds (73.8%). Spines are fairly pronounced. Fruiting canes produce averagely 19 relatively long (45 cm) fruiting branches which do not break under the weight of the crop. Self-fertile, abundant cropper with mid-early vegetation onset. It flowers mid-late. It is susceptible to spur blight caused by Didymella aplanata (Niessl) Sacc. It is highly resistant to cane and fruit botrytis caused by Botrytis cinerea Pers. Small colonies of Aphis idaei v.d. Goot and Amphorophora rubi ssp. idaei Borner, the aphid vectors of economically most serious raspberry viruses in our country occur sporadically. It is tolerant to these viruses.
The fruits are large (fruit weight about 4 g), firm, truncate conical, red colored. The number of drupelets within a fruit amounts to 120. Well-balanced in respect of aroma, with sugar content 6.1% and acid content 1.7%.
Fruits ripen mid-early to mid-late, almost simultaneously, so that it has a shorter ripening period (about three weeks). The fruits are easily picked. Transportability is satisfactory.
It is very suitable for both fresh use and freezing as well as for various forms of processing. 'Gradina' was moderately spread in Serbia (Valjevo and Čačak), but it is now practically non-cultivated. It was also grown in the southeast of France.
