Olives are native to China and can be eaten raw or processed. It is a famous subtropical fruit tree. Green fruit is a specialty of Fuzhou, which was listed as a tribute as early as the Tang Dynasty. The first time I ate Fuzhou olive, I felt bitter and astringent, and after the aftertaste, I felt fragrant and sweet. Fuzhou green fruits are mainly distributed in the lower reaches of Minjiang River, with Minhou and Minqing counties producing the most. Fujian is the province with the largest distribution of olive in China, and it is also cultivated in Guangdong, Guangxi, Taiwan Province, Sichuan, Zhejiang and other provinces. According to statistics, there are more than 200,000 mu of green fruit planting area, 50,000 mu of picking area and 20,000 tons of output in Fujian Province alone, with an average yield of less than 400 kg per mu, which is far behind citrus, loquat and longan.
Olives cultivated in China belong to the genus Olive. There are mainly two cultivated species, white olive and black olive, and a small number of wild species are distributed in Yunnan and other places. Olive has a cultivation history of more than 2000 years. After long-term natural and artificial selection and domestication, countless genetic resources have been formed. Most of the existing varieties are farm varieties bred by seedling groups, and their offspring have great variation, many intermediate characters and extremely rich variety resources.
The Fruit Tree Research Institute of Fujian Academy of Agricultural Sciences conducted a preliminary investigation on the germplasm resources of main olive producing areas such as Minqing, Minhou, Putian, Xianyou and Fuan, and found some important germplasm resources with specificity, such as "Four Seasons Olive".
