Abstract

Eurasian and interspecific grape varieties and candidates were inspected for biological productivity in the variety collection of the University of Debrecen at the Horticultural Experimental Station in Pallag. In this paper, data are reported on yields (kg/stock), cane production (kg/ stock) and use-up index of wood yield of each cultivar in the experimental years 2011-2012. From the range of Eurasian (Vitis vinifera L.) white wine-grape qualified cultivars and candidates ’Ezerfürtû’, ’Generosa’, ’Jubileum 75’, ’Müller Thurgau’, ’Zöld veltelíni’,’B-11’, ’CSFT-92’, ’Pintes’, from the range of Eurasian (Vitis vinifera L.) red wine-grape qualified cultivars and candidates ’Kármin’, ’Pinot noir’, ’Alicante Bouschet’ and ’Rubintos’ were highlighted. Promising data of interspecific ’Aletta’, ’Csillám’, ’Kunleány’, ’Orpheus’, ’Refrén’, ’Taurus’, ’Viktória gyöngye’, ’Alföld 100’, ’Reform’, ’RF38/32’, ’Toldi’ white, and ’Dunagyöngye’ ’Pannon frankos’ red wine-grape cultivars and candidates were emphasized. Published data refer only to the biological performance of the cultivars. The thorough evaluation of varieties needs respect to data on resistance to fungal disease and climatic extremities, and other characteristics concerning production technology and oenological parameters.

Highlights

The total yearly wine production of our country is dynamically decreasing from the generally accepted 3 million hl, even down to 2,5 of 2011, and 1,8 of the vintage of 2012
The variety collection of the University of Debrecen was established in Pallag, on immune sandy soil, by 3m between row and 1m between stock spacing trained for single curtain stock form, with the use of European own rooted planting material, which is serious information from the point of view of the evaluation of data on productivity
In the case of ’Cserszegi fûszeres’, ’Müller Thurgau’, ’Zenit’ and ’Zöld veltelini’, the higher generative production does not coincide with higher cane production

Summary

Introduction

The total yearly wine production of our country is dynamically decreasing from the generally accepted 3 million hl, even down to 2,5 of 2011, and 1,8 of the vintage of 2012. The reason for this decrease could be searched in the background composed of many well-known world-economic tendencies, measures done by the leap forward in the name of environmentally sound plant protection technologies, global climate change, dynamic change of wine taste of the world and so on, which would be hard to tackle with even one by one (Hajdu-Borbásné, 2009; Sidlovits, 2008; Eperjesi, 2010). The theoretical bases are well circumscribed in works of Csepregi (1982) and Diófási (1985), followed by Lörincz & Barócsi (2009)
