Coralis - a new sweet cherry cultivar for commercial plantations

Abstract

The aim of the paper is to improve the autochthonous sweet cherry assortment with new cultivars with late maturation and high quality fruits. The sweet cherry assortment from Romania contains many cultivars with maturation in the medium season. The current tendency is to create a balance by reducing the number of the cultivars with medium season maturation and by increasing the number of the cultivars with very early and late season maturation. Analyzing the main phenological stages for the two cultivars it was noticed that the new sweet cherry cultivar ‘Coralis’ is late both for the beginning of flowering time and for fruits maturation. Regarding the average productions on four years (2011-2014) from the statistical point of view, ‘Coralis’ cultivar (20.0 kg/tree) recorded positive production differences compared to the control cultivar (19.8 kg/tree). Under the aspect of fruits weight and equatorial diameter ‘Coralis’ (9.1 g and 24.7 mm) recorded significant differences and distinct positive significant differences compared to the control cultivar (6.9 g and 21.8 mm)
