Evaluation Adaptability of Some Sweet Cherry Cultivars for Meshkinshahr environmental Condition

Seven sweet cherry cultivars Stella, Sunburst, Germes dorfi clon3, Summit, Sabima and Siahmashad (Iranian cultivar) and Silegedelamarka (early ripen cultivar) were evaluated for some important fruit qualitative and quantitative traits and vegetative and reproductive characteristics, in RCBD design with three replications for three years (2007 - 2013). The cultivars were evaluated in two vegetative and reproductive phases in Meshinshahr Horticultural Research Station. High diversity was observed for flowering time, qualitative and quantitative traits. Based on the results, significant differences was observed for cultivars and fruit set percentage in open and artificial pollinations stages. The most spurs on two years old branches were belonged to Stella and Summit, as late flowering and leafing cultivars. The fruit set amount varied from 21% to 16% for Stella and Sunburst cultivars respectively, in self-fertility position. Silegedelamarka and summit cultivars had the least (5.5 g) and the highest (10.3g) fruit weight respectively. The highest vegetative growth were related to Siahmashhad, Sunburst, Germesdorfi3 and Sabima cultivars respectively. No significant differences were observed for titrable acidity, percent of TSS, the length of fruit tails and stone weight. The results showed that Stella, Sunburst and Summit cultivars can be recommended for Meshkinshahr region.
