NEW VARIETIES OF APPLE WITH GENETIC RESISTANCE TO DISEASE CREATED AT THE RESEARCH AND DEVELOPMENT STATION FOR FRUIT GROWING VOINESTI
Journal Title: FRUIT GROWING RESEARCH - Year 2018, Vol 0, Issue
Abstract
Between 2014-2017 at the Research Station for Fruit Growing Voinesti it was evaluated the performance of three brand new scab apple varieties: ‘Valery’, ‘Cezar’ and Revidar', all patented by ISTIS in 2016. The growth vigor of trees in the 10th year, grafted on the M9 rootstock, is well defined by the trunk circumference, which records between 14.9 cm in the ‘Caesar’ variety and 16.5 cm in the ‘Valery’ variety. The crown volume calculated at the surface unit and for a density of 2,857 trees/ha was of 8,200 mc/ha for the ‘Caesar’ and ‘Revidar’ and 8,900 mc/h for the ‘Valery’ variety. Productivity of trees in the ages of 7-10 years was between 35-40 t/ha in the ‘Caesar’ an ‘Valery’ varieties and 28.30 t/ha at the ‘Revidar’ variety. The fruit weight ranged from 160 to 190 g, smaller fruits being recorded in the ‘Revidar’ variety and higher in the ‘Caesar’ and ‘Valery’ varieties, which correspond to market requirements. The Remarkable quality of the varieties fruits recommends them for an increasingly demanding fruit market, meeting the current quality requirements and consumer’s needs.
