[Objective] This paper aimed to provide reference for future introduction and trial planting by analyzing the fruit quality characters of different date palm cultivars and germplasms in Pakistan and Hainan to understand the difference of date palm fruit quality. [Method] The 4 date palm cultivars (D,H,M,A) collected from Pakistan and 2 germplasms (R,Y) collected from Hainan were used to study the difference on fruit characters. The fruit characters, sugar and acid content, essential nutrient elements were measured. [Result] The fresh weight of single fruit of date palm from Pakistan was significantly higher than that of Hainan. The fruit length and diameter of 2 Pakistan date palm were significantly longer than that of Hainan. The content of xylose, fructose, sorbose, fructose, mannose, sucrose of sugar and the niacin, serine, malic acid of the date palm fruits collected from Pakistan were relatively high. The Mg contents in the 2 Hainan date palms were significantly higher than that in the 4 Pakistan date palms. Although the contents of different nutrients in different date palms were different, but the K. contents of 4 cultivars and 2 germplasms were almost the highest. The germplasm 1) and A growing in Pakistan were closely related to R and Y in Hainan, but far from II and M. [Conclusion] It was concluded that the fruit characters, sugar and acid content of the date palms were different between Pakistan cultivars and Hainan germplasms. Through this study, the difference of fruit quality between the date palms grown in Pakistan and Hainan was understood, which provided a reference basis for the purpose of introduction and trial planting in the future.
