Agrobiologic potential evaluation of some new sweet cherry varieties in order to improve upon the romanian assortment

Abstract

In Romania, Iasi area is one of the most favorable for growing cherries. Regarding the zonal assortment, it suffered constant renewal through continuous selection of local biotypes valuable and not least by introducing new varieties and rootstocks of cherry trees from abroad. The experiment was organized as an intensive cherry plantation. Biological material used consisted of five new foreign cherry varieties: ‘Kordia’, ‘Karina’, ‘Regina’, ‘Summit’, ‘Sunburst’, grafted on ‘Gisella’, vegetative rootstock. Cherry plantation was established in 2010 with planting distances of 4 x 2 m, resulting in a density of 1250 trees/ha. As a form of leadership trees crown was chosen Leader of the Central Vogel (VCL). New cherry varieties studied were noted by productivity and fruit quality: ‘Kordia’ 12.1 t/ha in the fourth year after planting (10.3 g fruit average weight), ‘Regina’ 10.2 t/ha, (10.6 g), ‘Karina’ 10.2 t/ha (9.7 g) and ‘Summit’ 10.0 t/ha (9.8 g)
