Description

The subject-matter of the patent application The white wine grape variety of the 109 varieties, which ripens very early compared to the present variety variety, is therefore suitable for extending the harvest period. Its excellent frost tolerance increases crop safety, its lower plant protection requirements and its high productivity can improve the economics of cultivation.

The grape variety of the present invention is clearly distinguishable from other varieties, sufficiently homogeneous and stable. There is no variety in the domestic and foreign varieties that could be confused with.

Practical viticulture is becoming increasingly popular with varieties that are distinguished by their resistance. Multiple cross-breeding allows resistance to be genetically combined in a variety in a favorable combination with quality.

The vine variety of the present invention serves the above purposes and relates to a vine variety having a high degree of resistance to production.

Thanks to its soup with berries, it is easier to press and has a higher yield than other resistant grape varieties produced with American resistance sources, such as Zalagyöngye, Bianka, Viktória pearl.

Despite the origin of the hybrid, the wine does not differ negatively from the traditional varieties. With the right vintage and wine technology, quality wine can be made from must.

The wine grape variety according to the invention was selected from the progeny of the cross between the self-produced species hybrid 28/19 and the Chardonnay blanc variety and was first propagated and then planted.

Based on the technical examination of DÚS according to UPOV guidelines, the detailed description of the variety is as follows:

The patented variety has excellent frost tolerance and significant resistance to the two most important fungal diseases, mildew and powdery mildew.

This degree of resistance to the two diseases does not allow complete elimination of the chemical control of the fungal diseases, but according to our many years of experience 2 or 3 sprayings per year are sufficient to protect against these two pathogens. The variety is moderately susceptible to Botrytis, but due to its very early ripening it is not attacked by this pathogen in most vintages.

Due to its resistance to powdery mildew and downy mildew, it is suitable for environmentally friendly cultivation technology using few pesticides. Its proven resistance to artificial infections against Agrobacterium goiter is a new and unique feature both domestically and internationally. The wine has a clear taste, a harmonious acidity and a light, fresh character, but also rich and long, at the right time of harvest.

Figure 1 shows the shoots, leaf shapes, and the shape of the cluster and the berry of the patented grape variety.

The variety has medium productivity. Due to its vigorous growth and vitality, its capital does not weaken even in large quantities of ter45.

Based on the 15-year average, the yield per IRP is 1.39 kg, the highest for the other comparative varieties, Rhine Rizling, Zalagyöngye and Kunleány.

The yield values of the fruit are sufficient even for large yields, for self-production without repair. The sugar content of must must reach a

18-20 black degrees. The titratable acidity is 8-9 g / l. During ripening, the sugar content of the must may continue to increase, but at the same time the acidity is significantly reduced, which is unfavorable from an oenological point of view.

Its cluster is small to medium, its average weight is 120-130 g. The berry is small and weighs 1.2 g.

The breed's outstanding frost resistance has been demonstrated by both field experience and climate chamber testing over the past two decades.

The high yields obtained after the winter of HU 221 706 B1 (1985, 1987) are the best indicators of its frost tolerance.

At -18.5 C °, the anthrax damage was 13%, while the side bud damage was 4%.

During the tests with artificial frost treatments, the frost tolerance of the variety was also convincing even at lower temperatures.

-21 ° C during freezing artificial, these values were 40% and 8%, while it was 66% and 35% in refrigeration, -24 ^o C. 10

The bud bud and the beginning of flowering are both very early, 5 days ahead of the early budding and flowering varieties. The ripening period is very early and is suitable for widening the harvesting period, typically in the first days of September, at the same time as the Zalagyöngye variety with a sufficient technological maturity.

Figure 1 clearly shows the strong shoot growth, the shoots are drooping, the axillary shoots are strong, resulting in a dense foliage. The stalk is short to medium in length, moderately woody. The cluster is small, medium to loose with a density of 20. The size of the berries is small and their ripeness is even in the cluster. Its color is greenish yellow and its surface is slightly to medium ashy. Its shape is round. The cane is tan-colored and has a bare surface. The shape of the leaf is pentagonal, three-armed, dark green with a slight blistering surface.

Advantages of the patented variety:

- due to its very early ripening it is suitable for extending the harvest period,

- its excellent frost tolerance enhances crop safety,

- requires environmentally-friendly cultivation techniques, since it has a high resistance to powdery mildew and downy mildew,

- has complete resistance to Agrobacterium goiter. This feature is unique in the world,

- its soup with berries makes it easier to press and has a higher degree of origin than other wine grape varieties,

- the quality of the must may be obtained from must, provided that the wine is harvested and harvested appropriately,

- its abundant fertility and its listed advantages justify its widespread dissemination.
