Abstract: The fruit quality of Fuji apple in various ecological regions of China and its major affecting meteorological factors were studied by investigation, laboratory analysis and multiple statistical analysis. Fuji apple fruits in the loesss plateau of Weibei and Longdong areas of northwest China, and in the Bohai Bay of Shandong Province had a high weight per fruit, and a glossy and gaily colored fruit skin; while those in mountainous region of southwest China had a dull red skin, in the former course of Yellow River had a rough and poor colored skin and in Ningxia Province had small sizes. The major meteorological factors affecting fruit quality were selected by canonical correlation analysis. The anthocyanidin content of fruits was affected mainly by annual total precipitation, and average temperature in October, maximum average temperature in July, and minimum average temperature and sunshine hours in September.
