Comparison of Fruit Quality of Excellent Single Plant of Xinjiang Peach

Taking 7 Xinjiang peach germplasm resources as test materials, the fruit quality were compared in this study to clarify fruit quality of individual plant in Xinjiang, in order to provide new germplasm resources for the development of Xinjiang peach industry.The results showed that the single fruit weight of 7 Xinjiang peach germplasm ranged from 125.39 g to 198.89 g, and there were significant differences among germplasm.The single fruit weight of ‘Maotao No.4’,‘Maotao No.1’ and ‘Maotao No.3’ were significantly higher than that of other germplasms.The soluble solids content of 7 Xinjiang peach germplasm ranged from 9.88% to 13.95%.The soluble solids content of all germplasm except ‘Youtao No.2’ exceeded 12%.The soluble sugar content of 7 Xinjiang peach germplasms ranged from 3.05% to 13.91%,and there were significant differences among germplasms.The soluble sugar content of ‘Maotao No.4’ and ‘Maotao No.1’ were significantly higher than that of other germplasms, and the titratable acid content was between 0.57% and 1.74%.There were great differences among germplasms, and the titratable acid contents of ‘Maotao No.5’ and‘Youtao No.1’ were significantly higher than those of other germplasm.7 Xinjiang peach germplasms showed a variety of fruit shape, color and flavor.According to the comprehensive analysis of external quality and internal quality, it was found that the fruit quality of‘Maotao No.4’ was the best, which can be popularized and applied in Xinjiang.
