Abstarct: Sweet Cherry (Prunus avium L) is one of the most important fruits in the world's temperate regions. In order to study adaptability of five new introduced sweet cherry cultivars (Stella, Sunburst, Summit, Subima, Germesdorfi coln3) with two control cultivars (Siah Mashhad as the compatible native and non-native varieties adapted Sileg Belamarka), a compound experiment on the baxsed CRBD with three replications was conducted in Shahrood Agricultural Research Station in two consequensive years 2015-2016. The results showed that the highest and lowest tree height and tree canopy extension was observed in the Summit and Sunburst cultivars, respectively. Stella cultivar has largest annual growth and Germesdorfi coln3 has the lowest once. There are significant differences among cultivars in flowering phenology stages. The Siah Mashhad and Germesdorfi coln3 are early blooming and the Summit and Stella are late blooming varieties. The highest and lowest percentage of fruit set was respectively observed in sileg delamarka (60.93 %) and Stella (20.14 %) in 2015 and sileg Belamarka (65.16 %), Siah Mashhad (64.17 %) and Summit (61.56 %) have the highest percentage of fruit set in 2016. The highest yield was observed in Stella with 55 kg/tree and the lowest yield was 15 kg/tree in Sunburst. In artificial self pollination without emasculation, fruit set in Stella, Sunburst and Germesdorfi coln3 was 20.81, 19.9 and 6.7 percent, respectively and in artificial pollination with emasculation fruit set of Sunburst, Stella and Germesdorfi coln3 was 24.7, 14.87 and 6.2 percent, respectively which showed complete compellability in self pollination in Sunburst and stella and reletive complebility in Germesdorfi Coln3. The sunburt cultivar with 7.4 gr in fruit weight mean have largest fruit and Siah Mashhad with 4.25 gr in fruit weight has smallest fruit in compare other investigated sweet cherry cultivars. The highest percentage of fruit juice was observed in Stella and Sunburst and the lowest once was observed in Subima cultivar. The Germesdorfi coln3 fruits has maximum flesh firmness,2 kg/cm2, and Siah Mashhad has minimum flesh fimness,1.12 kg/cm2 . The Stella fruits selected for highest overall acceptability by customers in organoleptic panel test. The result of this research showed that Stella, Summit and Subima cultivars have good adaptability to Sharood climate (Bastam).
