The behavior of some sweet cherry cultivars in southeastern Romania

The Research Station for Fruit Growing Constanta is located in southeastern Romania and has a long history in temperate stone fruit breeding, growing and extension to various orchard owners.
During 6 years, the aim of the study was to establish the behavior of 31 sweet cherry cultivars grafted on Prunus mahaleb (the main cherry rootstock in our area). All studied cultivars were observed in nursery and orchard, too.
In the nursery the number of grafted trees and the height of the plants were noted; in the orchard the fertility coefficient obtained through free pollination and auto-pollination was evaluated and the precocity of fruiting was noted.
The statistical data of growing showed the following conclusions: ‘Cerna’, ‘Severin’, ‘Ponoare’, ‘Jubileu 30’, ‘Cetatuia’ and ‘Amar Galata’ were considered the most suitable sweet cherry cultivars for intensive cherry orchards.
Free pollination was minimum 20-40% for ‘Ponoare’, ‘Amara’ and ‘Colina’ and maximum 70.2-83.3% for ‘Izvena’, ‘Summit’, ‘Rainier’, ‘Viscount’. We can consider only ‘NY 13272’, ‘Summit’ and ‘New Star’ cultivars as being partial auto-incompatible with 11% of fruit obtained through self-pollination.
