Analysis on fruit quality characteristics of Amygdalus ferganensis var nectarine

【Objective】 Objective to analyze and evaluate the fruit quality characteristics of Amygdalus ferganensis var nectarine germplasm resources in Aksu region of Xinjiang, so as to provide technical support for Xinjiang nectarine breeding.【Method】 Seven fruits of excellent germplasm resources of A. ferganensis var nectarine around Aksu City of Xinjiang in the northern margin of Tarim Basin were selected as the research objects. (two kinds of A. ferganensis were used as control). The sensory characteristics, flavor quality and functional nutritional quality of peach fruit were determined.【Results】 The single fruit weight of A. ferganensis var nectarine in Aksu area is 29.90-74.62 g, the minimum single fruit weight (29.90 g) is lower than the minimum value of 150 nectarine varieties in China (40.00 g), with an average of 50.08 g. The contents of soluble solid and soluble sugar were more than 12% and 9% respectively. However, the skin hardness of A. ferganensis var nectarine fruit is less than 3 kg/cm².【Conclusion】 The fruit of A. ferganensis var nectarine are quality excellent and tastes delicious, and its shape belongs to two grades: very small and small, and the content of soluble solids and soluble sugar belongs to high or very high grade. The storage and transportation intolerance is the key factor limiting the development of A. ferganensis var nectarine.
