The Bulgarian plum cultivars 'Goulyaeva', 'Balvanska slava', 'Gabrovska', 'Strinava' and 'Nevena' were bred at the Plum experimental station in the town of Dryanovo. These cultivars were studied in the period 2002-2006. Measurements taken were: yield, mechanical composition of the fruits, the content of dry matter, glucose, fructose, saccharose, organic acids, nitrogen, phosphorus, potassium, calcium and magnesium. The plum cultivars 'Goulyaeva', 'Balvanska slava', 'Gabrovska' and 'Strinava' were highly productive. Their yield surpassed 20 t/ha. The fruits of the studied cultivars were large and very tasty. The dry matter ranged from 19.17 to 23.10%. The fruits of 'Strinava' and 'Goulyaeva' had higher sugar contents. The content of nitrogen in the fruits varied from 0.62 to 0.83%, phosphorus from 0.11 to 0.15% and potassium from 0.76 to 0.98%. The Bulgarian plum cultivars 'Goulyaeva', 'Balvanska slava', 'Gabrovska', 'Strinava' and 'Nevena' are productive, with large and tasty fruits and tolerant to some economic important diseases; they are suitable for propagation in plum growing regions in Bulgaria.

Plum is a fruit species traditionally grown in Bulgaria. Plum orchards in Bulgaria have been situated in four basic industrial and commercial regions. The main plum production region is the Central Balkans, which have favorable environmental and economic conditions. The plum orchard area in Bulgaria reached its maximum in 1965-53 300 ha and since then has begun to decrease and in 2004 was down to 10 967 ha. Two cultivars 'Kyustendilska sinia sliva' and 'Stanley' have been included in the plum orchards and during the last 15-20 years 'Stanley' has predominated. The technology for biological plum production includes pruning, fertilizing and plant protection. The applyication of green manure is recommended as one of the modes for maintaining the soil surface in plum orchards. Suitable green crops are rye, repko, winter forage peas, or a peas-rye mixture. It is recommended that new and different plum cultivars, highly productive and tolerant to Plum pox virus, such as 'Ruth Gersteter', 'Opal', 'Chachanska lepotitsa', 'Tuleu timpureu', 'Althan's gage', 'Green gage', 'California blue', 'Gabrovska', 'Strinava', 'Hramova renkloda', 'Stanley', 'Mirabelle de Nancy', 'Valevka', 'Bluefree', 'Nevena', 'Anna Schpett' are planted, as well as some local plum cultivars, which are tolerant to diseases, such as 'Biala Razgradska', 'Klestachka', 'Medenka', 'Tarkulka', 'Zimna karadjeika', 'Pushevka', 'Drebna biala rakyinitsa' and 'Sinia rakyinitsa'.
