Ivo Miljković

Abstract

In the area Gornje Međimurje apple culture has a long and famous tradition. Growth has been extended to a large number of domestic and old fashioned varieties. This has contributed to favorable ecological conditions and the expansion of the variety from the Vukanovec republican fruit nursery. For apple breading it is necessary to have rich germplasm and to know the properties of varieties. The paper presents the results of the research of the chemical compositions of 40 varieties, including dry matter, soluble dry matter, total sugar, acidity, pH value and quality score of the Thiault index. Among
varieties are: Ananas Renette, Bauman's Renette, Batulemapfel, Belle Fleur, White Winter Tafetapfel, Yellow Transparent, Blenheimere, Grosse Rheinischer Bohnapfel, Boskoop, Roter Haslinger, Cox's Orange, Red Autumn Kantapfel, Danziger Kantapfel, Funtacha, Golden Delicious, Gravenstein, Harbert's Renette, Jonathan, Renette du Canada, Grosse Kaseler Renette, Rheinischer Krummstiel, Landzberger Renette, Laška Trdika, London Pepping, Steirische Maschanzker, Ontario, Schafsnase, Parker Pepping, Red Delicious, Ribston Pepping, Renette Grise Francaise, Renette Grise Automne, Geflamanter Kardinal, Rambur, Renette de Champagne, Željeznika, Reine de Reinette, Gruner Stettiner, Charlamowsky and Starking. The fruits of the following varieties have the highest content of dry matter (above 17%): Blenheimere, Boskoop, Harbert’s Renette, Renette du Canada, Parker Pepping, Ribston Pepping, Renette Grise Francaise, Renette Grise Automne. The fruits of the following varieties have the highest soluble dry matter (above 15%): Baunab’s Renette, Harbert’s Renette, Grosse Kaseler Renette, Landzberger Renette, Roter Haslinger, Danziger Kantapfel, and Batulemapfel. Highest amount of sugar (13 - 15%) contain fruits of varieties: Blenheimere, Renette Grise Automne, Ribston Pepping, Parker Pepping, Boskoop, Renette du Canada, Harbert’s Renette, Belle Fleur, Reine de Reinette, Golden Delicious, and Steirische Maschanzker. Most acids (over 7 g/l) contain varieties:
Yellow Transparent, Boskoop, Red Autumn Kantapfel, Renette du Canada, Laška Trdika, Steirische Maschanzker and Geflamanter Kardinal. The varieties that have the best quality (Thiault index above 170) are: Ribston Pepping, Renette Grise d’Automne, Parker Pepping, Boskoop, Renette Grise Francaise, and Renette du Canada.
