Morphological, agrobiological and technological investigation of the vegetative pedigree of the selected elite seedling 8-92 (3-32 I1) was made together with Galina Dyakova.

Tangra cultivar is late-ripening (it ripens about 5-th October), a typical table seedless variety. The cluster is large, uniform, average weight being about 400 g. The berry is coarse (5.5 g), red-black, with crispy consistence, the taste – neutral harmonious. The seeds are rudiment and they have no unpleasant taste in consumption of grapes. Dry weight of rudiments in 100 berries is 0.30 g.

Zornitsa cultivar is a typical table seedless variety, ripening during the second half of September. The cluster is large (400 g), uniform, and the berry is coarse (4.9 g), red-grey colored.

Dry weight of rudiments in 100 berries is 0.22 g.

Yield of grapes per a hectare is about 16 t. The vines are cold resistant and grapes – with good transportability. Appropriate root stocks for the variety are SO4, Chasselas X Berlandieri 41B and Rupestris du Lo. Recommended formations are half-standard Guyot and Lira.

RUSENSKO BEZ SEME

It ripens towards 20 of September. The cluster is semi-large, 300 g, semi-compact. The berry is coarse, 3,5 g, ovate, green-yellow with pink. The consistence is crisp, the taste – neutral. The yield of grapes is 1,4 t/da. The grapes contains 20% sugars and 8,0 g/l acids. In a later vintage, the sugar content increases to 24-26%, this flavors the raisins production. The cultivar is with increased winter resistance and is rot resistant.

It is recommended to be cultivated at the typical for the table grapes production regions.

BOLGAR CLONE 14

It ripens at the usual for the cultivar time – from 10 to 15 September. The cluster is very large, 640 g (500 g for the population) loose to semi-compact, uniformed in size and berries coloration. The coefficient of fruit bearing is 0,9, 0,7 being for the population. The clone gives up to 20% higher grapes yield than the population. The taste and the coloration of the berries are typical for Bolgar variety. Compared with the population, the clone is with quite lower susceptibility to putting forth aments and abscission of the berries.

Bolgar clone 14 can be cultivated at the typical for the cultivar vine-growing regions.

MISKET RUSENSKI

It ripens at the end of July, the beginning of August, 15 days before Kardinal. The cluster is large, 300 g, loose. The berry is large, 4,8 g, ovate, black. The consistence is crisp, the taste – musket. The yield (t/da) is 1,3. The grapes are rot resistant and transportable. It contains 16% sugars and 4,3 g/l acids.

The cultivar is appropriate to be grown at all vine-growing regions and hilly areas up to 700-800 m above sea level.

SIYANA

It ripens at the middle of October. The cluster is large, 530 g, loose. The berry is very coarse, 10 g, long, black, with 2 seeds mid-size. The consistence is crisp and the taste – neutral. The yield of grapes is about 2 t/da. The grapes contains 17% sugars and 5,4 g/l acids. It preserves fresh on the root for a long time after the ripening and is highly transportable.

The cultivar is recommended for production of late table grapes intended for realization on the market also in winter. It is recommended to be cultivated at the warmest regions of the country.

PAMID RUSE 1

It ripens at 12-15 of September, 10 days earlier than Pamid cher. The cluster is mid-large, 260 g. The berry is 3,2 g, 30% larger in weight and size than Pamid cher. The grapes contains more sugars (19,2%) and acids (3,92 g/l), compared to the control form 18,5% and 3,25 g/l, respectively. The yield of grapes is 1,9 t/da. Pamid Ruse 1 does not put forth aments and abscission of the berries is not observed. It manifests a strong recruiting ability in frost bite and with lower susceptibility to powdery mildew and rot.

It is appropriate for consummation in fresh condition and for making of qualitative wine.

RYAHOVO

It ripens towards 25 of August. The cluster is semi-large, 450 g, semi-compact. The berry is very coarse, 7,0 g, ovate, green-yellow. The consistence is crisp, the taste – delicate musket. The yield of grapes is 2,0 t/da. The grapes contains 16% sugars and 5,0 g/l acids. It is transportable. The thinning out of berries 10-15 days before ripening sharply increases their sizes and betters the appearance of the cluster.

The cultivar can be cultivated at the typical viticultural regions in the country and at foothill places under lee and in the sun.

VELIKA

It ripens towards 20 of August, at one and the same time with Kardinal. The cluster is large, 500 g, loose. The berry is very coarse, long, black, with 1-2 small often soft seeds. The consistence is crisp and the taste – neutral, harmonious. The yield of grapes is over 2 t/da. The grapes contains 16% sugars and 6,0 g/l acids, which determines its high gustatory qualities. It has a good transportability.

The cultivar can be cultivated also at foothill places, facing south and 400-500 m above sea.

PRISTA

It ripens towards 15 of August, before Kardinal. The cluster is large, 380 g, semi-compact. The berry is coarse, 5,3 g, ovate, green-yellow. The consistence is crisp, the taste – musket. The yield of grapes is 1,5 t/da. The grapes contains 16% sugars and 4,0 g/l acids. It is transportable and rot resistant.

The cultivar is appropriate for production of early grapes in the open and in glass houses. The cultivar can be cultivated also at foothill places up to 600-700 m above sea.

It is comparatively early ripening, with strong growth and good productivity. The length of the vegetation period from budding to the physiological maturity of grapes is about 155 days. The consumptive ripeness of grapes in the region of Rousse occurs around September 15.

Misket Viking is a typical wine variety. The cluster is medium-sized (16-17 cm), conical, sometimes winged, medium compact, with short to medium long fruit stalk (4-7 cm). The berry is medium-coarse (13,71/13,14 mm), oval, yellow-green colored, with musket flavour.

It is early ripening with strong growth and good productivity.

The length of the vegetation period from budding to the physiological maturity of grapes is about 150 days. The consumptive ripeness of grapes in the region of Rousse occurs around September 5.

Kristalen is a typical wine variety. The cluster is medium-sized (16 cm), conical, sometimes winged, medium-compact, with a short to medium-long stalk (4-7 cm). The berry is medium (14.53/13.51 mm), oval, yellow-green colored, with musket flavour. The average weight of cluster is about 196.5 g, and berry – 2.73 g. The consistency of berry is fleshy and juicy, and the taste is harmonious with a musket flavour. At consumptive maturity, the grapes contain 19.26% sugars and 7.42 g/l titratable acids, do not crumble and have a very good transportability.

The grapes have pronounced fruity and musket flavour, pleasant freshness and are suitable for the production of white high quality wines, dense and with good harmony between alcohol, sugars and titratable acids and for the production of high alcoholic beverages.
