Evaluation of pomological traits of some new sweet cherry cultivars under Karaj condition

Evaluation of pomological characteristics can be useful in selection of best cultivars for commercial purposes. During this project, seven cultivars of sweet cherry including five cultivars from Hungary (‘Stella’, ‘Sunburst’, ‘Germesdorf’, ‘Summit’ and ‘Subima’) and two control cultivars (‘Cillage Blamarka’ and ‘Siahmashad’) were studied by Completely Rondomized Blocks design with three replications during two years in Kamal Shahr Horticulture Research Station. Comparison of average fruit weight showed that ‘Sunburst’ had the largest fruit size (7.21 g), fruit length (23.23 mm), fruit width (23.7 mm) and fruit volume (7.09 cc) whereas the Blamarka’ had the lowest values. Average of Total Soluble Solids (TTS) ranged from 22.59% in ‘Siahmashad’ to 18.29% in ‘Stella’ cultivar. Results of this study showed that ‘Sunburst’ had the best pomological characteristics in Karaj climatic conditions. Furthermore, the Sunburst displayed self-compatibility characteristic and, therefore, may be the preferred cultivar relative to incompatible cultivars such as Siahmashhad.
