Abstract

The results of the testing of three new Polish apple varieties grown under the conditions of Kyustendil, Bulgaria during the first six years after planting (2012-2017) are presented. Earliest flowering time was recorded in ‘Gold Milenium’ (15 April) and the latest in ‘Melfree’ (20 April). Average ripening date was between 30 August (‘Melfree’) and 25 September (‘Free Redstar’). The trees of Gold Milenium’ had stronger growth. No significant differences were found in the productivity of the cultivars. Fruit weight range from 168.2 (‘Melfree’) to 198.0 g (‘Gold Milenium’). With the most harmonious flavor were the fruit of ‘Gold Milenium’. No symptoms of apple scab and powdery mildew were found. Preliminary data showed that all three cultivars are suitable for growing in the Kyustendil region.
