Abstract
Over 2001 - 2002, studies were conducted at the Experimental farm "Radmilovac", collective strawberry planting of the Faculty of Agriculture, Belgrade. The experiment included three strawberry cultivars, two newly introduced cvs, Marmolada and Elsanta, and standard cultivar Senga Sengana. All cultivars were grown on banks covered with black polyethylene foil, in the form of two row bands. Various intrarow distances were applied: 15, 20, 30 and 40 cm, whereas interrow distances were fixed at 30 cm. Flowering time as well as major parameters of generative potential (morphological inflorescence properties and cropping of strawberry cultivars) were studied at different planting distance. The best results for the most studied parameters were obtained in cv Senga Sengana, but this cultivar had the smallest fruits among studied cultivars. Newly introduced strawberry cultivars Marmolada and Elsanta had larger fruits with lower yield per plant. Lower generative potential of the newly introduced... strawberry cultivars over the studied period, can be explained by its demand for permanent application of all agro-pomological techniques, and utilization of permanent drip irrigation system under our agro-ecological conditions in particular. That is why cv Senga Sengana can be recommended for processing and more intensified growing under conditions of the Belgrade region. At the same time, the larger planting distance of 30 x 30 cm and 40 x 30 cm, where the highest values were recorded, positively influenced values of the stated parameters of generative potential, whereas the lowest values were recorded at smaller planting distances, 15 x 30 cm and 20 x 30 cm.

Istraživanja u ovom radu, obavljena su u kolekcionom zasadu jagode Poljoprivrednog fakulteta iz Beograda, na Oglednom dobru "Radmilovac" u periodu 2001 - 2002. godine. Ogledom su bile obuhvaćene tri sorte jagode, dve novointrodukovane: Marmolada i Elsanta, i kao standard sorta Zenga zengana. Proučavano je vreme cvetanja, kao i važniji parametri generativnog potencijala (morfološke karakteristike cvasti, procenat oplodnje i rodnost sorti jagode) u funkciji različitih rastojanja sadnje. Najbolje rezultate kod većine analiziranih parametara ostvarila je sorta Zenga zengana (standard), ali je imala i najsitniji plod među ispitivanim sortama, te bi se mogla preporučiti za šire gajenje kao industrijska sorta u uslovima gročansko-smederevskog Podunavlja. Istovremeno, pozitivan uticaj na vrednosti pomenutih parametara generativnog potencijala imala su veća rastojanja sadnje 30 x 30 cm i 40 x 30 cm, na kojima su ostvarene najveće vrednosti.
