In order to evaluation new sweet cherry includes seven cultivars: Stella, Sunburst, Germesdorfi clon3, Summit and Sabima and Iranian national cultivar ”Siahmashad” and Silege delamarka as a early ripen cultivar cultured in RCBD design with 3 replication and 4 trees in each block. Evaluations that was achieved for 3 years (from 2007) include: vegetative traits (annual growth, stem diameter, canopy extension, tree height, flowering and leafing date and Number of spurs on 2 years old branches), bearing and some qualitative and quantitative traits. Analysis of variance on vegetative traits achieved in three years and compared of means. Results showed that Flowering date, qualitative and quantitative traits of cultivars are various. Cultivars had significant differences between percent of fruit set at 2 open and artificial status of pollination. Stella and Summit cultivars was late flowering, late leafing and showed abundant spurs on 2 years old branches. Stella and Sunburst have 21 and 16 percent self-feretility respectively. Silege delamarka and summit have lowest (5.5gr) and highest (10.3gr) fruit weight respectively. Siahmashhad, Sunburst, Germesdorfi3 and Sabima had the highest vegetative growth. These cultivars hadn’t any significant differences on stem diameter in 3 years that analyzed of variance.
