It resulted from the cross of 'Wangenheims Frühzwetsche' and 'Požegača'. Hybridization was carried out in 1961. It was named and released in 1975. The breeders were Dr. Staniša A. Paunović, Dr. Milisav Gavrilović and Dr. Petar Mišić.
The tree is vigorous to very vigorous on Myrobalan seedling. The crown is relatively sparse, pyramidal, with high bearing capacity. Bearing wood is well distributed along thinner and thicker branches. It bears fruit mostly on fruiting spurs and one year old branches. Flower buds contain approximately 1.66 flowers. The leaf is relatively large, long-ovate with crenate edges. The petiole is medium thick, short, with few glands at the base. The flower is medium large, with white petals. Flowering time is mid-early with 'Čačanska Rana', 'Čačanska Lepotica', 'Čačanska Rodna' and 'Ruth Gerstetter'. Self-sterile. Pollinators: 'Čačanska Lepotica', 'Ruth Gerstetter', 'Čačanska Rodna', 'Zholta Butilkovydna', etc. It has a high yielding potential, which varies by locality, weather conditions at bloom, rootstock, etc. A regular and heavy cropper under favorable conditions. Moderately susceptible to causal agents of red leaf spot (Polystigma rubrum Pers.) and plum rust (Puccinia pruni spinosae Diet.). Resistant to fruit and flower rot (Monilinia laxa). Highly tolerant to Plum pox virus, with localized infection only. It produces steady yields on blackthorn.
The fruit is cylindrical, very large (44 g), attaining sometimes 90-100 g. Dimensions: length - 43.8 mm, width - 39.5 mm, thickness - 39.4 mm. Skin is medium thick, tough, deep blue to black with heavy silvery bloom. Suture line is distinct, dividing fruit into equal halves. Stalk is medium long, firm, adhering tightly to fruit. Flesh is yellow, very firm, juicy, sweet-subacid and moderately aromatic. It contains 16.8% soluble solids, 10.3% total sugars and 0.83% acids. Fruits are very attractive. The stone is large (1.76 g), long-ovate, blunt at base, of light tan color, freestone. Dimensions: length - 25.7 mm, width - 15.0 mm, thickness - 9.8 mm.
Ripens 3-5 days before 'Stanley', at the end of the second-beginning of the third decade of August. A very good shipper. Fruit hang well and long on the tree and can be picked before full maturity as it takes on blue color early.
A high quality dessert cultivar, of great vigor and high yielding potential. It should be grown under favorable conditions of vineyard areas on dwarf rootstocks (St. Julien, blackthorn, etc.) with suitable pollinators. Highly suitable for freezing and also for drying and brandy making. It is grown in many European countries and in New Zealand.
