In a young apple orchard with scab resistant varieties on the Romanian plain, trees were planted at 3.5 x 1.0 m on a brown-reddish soil and led as vertical axe. A trellis formed with 4.0 m oak wooden poles, 2 wires and bamboo canes was used to lead and to support the trees. The inter row was cultivated with a mixture of perennial grasses and mowed mechanically. Drip irrigation was provided on the row, having a continuous line with auto compensating drippers every 0.5 m. On the row, the soil was maintained clean by hand and mechanical cultivation. Organic foliar and soil fertilization was applied. For consecutive three years, fruits from 22 varieties have been studied during fruit storage, from September until April. Fruits main physical and biochemical characteristics were analyzed: fruit weight (g), fruit calibre (mm), flesh firmness (kgf/cm2), soluble solids (%) etc. Fruit starch content was determined, based on the conversion level in soluble solids by coloration of the fruit transversal section. Sensory analysis of fruit have been realised by appreciating the external and internal fruit characteristics using a descriptors list for the ”Level 1” of the “Eurofru” fruit test. Gold Rush had the best appreciations from the taste quality point of view, 45.40% of the tasters considering it of good quality and 25.20% of them, of excellent quality. Average fruit weight ranged from 89.8 g for Red Devil up to 232 g at Topaz. Flesh firmness at harvest ranged between 4.6 kgf/cm² at Rajka up to 13.8 kgf/cm² at Gold Rush variety, being an important indicator of fruit earliness and ability to storage.
