Ivo Miljković
Sažetak
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.
