Evaluation of generative accomplishment of new apple cultivars in Hungary
International journal of horticultural science
In a two year study, 14 new apple cultivars (cvs 'Gala Venus Fengal', 'Gala Decarli-Fendeca', 'Galaval', 'Jugala', 'Gala Schnitzer (S) Schniga', 'Red Cap Valtod (S)', 'Early Red One', 'Jeromine', 'Crimson Crisp (Co-op 39)', 'Red Topaz', 'Wilton's Red Jonaprince', 'Red Idared', 'Fuji September Wonder' and club cultivar) were studied in Eastern Hungary at Nyírbátor. The following parameters were measured: trunk cross sectional area (cm2), harvest time with yield (date, kg/tree, number/tree),
... number/tree), fruit size (mm), fruit surface color (%), and color intensity of the fruit surface (1-5). According to our two year assessments regarding, the best generative accomplishment was achieved for the cvs 'Gala' sorts trained to slender spindle and the cv 'Red Jonaprince' trained to super spindle. According to the trunk cross sectional area the 'Gala' sport trained to slender spindle showed the strongest growth among the 4 years old trees, while the cv 'Fuji SW' and the cv 'Jeromine' presented lower vegetative accomplishment. The ripening time of the cultivars started at the end of August and finished at the beginning of October. 'Gala' mutants trained to slender spindle provided the highest yields. Fruit size of all cultivars reached the market required standard, however, cvs 'Red Jonaprince' and 'Red Idared' produced large fruits over 90 mm. The fruit size of the 'Gala' sort was 72–75 mm. Most of the cultivars showed high fruit surface color and color intensity.
