Determination and Evaluation of Fruit Quality of Sweet Cherry Cultivars in Southern Xinjiang

11 sweet cherry cultivars introduced in Southern Xinjiang were evaluated with 13 fruit quality factors(L^*,a^*,b^*,single fruit weight,fruit shape index,fruit hardness,total soluble solid,total sugar,total acid,sugar acid ratio,protein content,V_C content,moisture),and comprehensively evaluated by their physical index,chemical index,sensory index and principal component analysis. The results showed that,in purple black sweet cherries,the single fruit weight of Early big and Tieton were 7.35 g and 6.88 g,significantly higher than other cultivars. The fruit hardness of Early big was higher than Tieton. The single fruit weight and fruit hardness of Lapins were 6.51 g and 0.79 kg/cm². The single fruit weight and fruit hardness of Sunburst were 11.70 g and 1.06 kg/cm² and 1.06 kg/cm².In the field of total soluble solid and sugar acid ratio,the Lapins and Sunburst were higher than the Early big and Tieton. The Early big and Tieton had fine pulp texture,thin skin and soft taste. The Sunburst and Lapins had tight pulp texture,thick skin and crisp taste. Analysis by synthesis,the comprehensive quality of the Early big and Tieton in purple black,the Lapins in scarlet,and the Sunburst in red were the best. They could be moderately planting in Southern Xinjiang.
