With the local major cultivar Leccino as the control, the fruit quality, yield and early maturing property of introduced olive cultivars (Koroneiki, Arbequina, Hojiblanca) from Spain were studied. The results showed that there were differences in fruit traits such as single fruit weight, ratio of flesh content, moisture content and oil content between different cultivars. The yield of early maturing property of the introduce cultivars were better than those of Leccino. The introduced varieties can fruit after 1-2a, showing early maturity and high yield. This can provide a theoretical reference for the cultivation of olive in Longnan.
