Abstract :Avocado cultivation in the world and Turkey, especially Hass cultivar, increases rapidly in recent years. The fruit quality of avocado is directly related to harvest maturity and post-harvest ripening process and the identification of maturity index has a very large commercial importance. For this purpose; in the fruit samples of Hass cultivar taken at 15-20 days interval from October to June, some fruit quality traits insert ignore into journalissuearticles values(dry matter, flesh firmness, weight loss, taste, colour of fruit skin and flesh); during the harvest and ripening process and relationships between of these parameters were analysed. As a result, it was found that the most reliable maturity index was the dry matter insert ignore into journalissuearticles values(DM); content and that there was a direct relationship between its accumulation and the harvesting time. In cases these index values were insufficient, the other postharvest analyses insert ignore into journalissuearticles values(taste, fruit skin colour, fruit hardness and weight loss); made a contribution to determination of maturity. During the ripening process, very high levels of a positive correlation between harvest time and dry matter insert ignore into journalissuearticles values(r= 0.92 to 0.96); was observed. According to the fruit maturity of the Hass cultivar, three different harvest periods were defined as early, optimum insert ignore into journalissuearticles values(most suitable); and late harvests. It was determined that from early October to late December as early harvest insert ignore into journalissuearticles values(23-25% DM);, from January to late May as optimum harvest insert ignore into journalissuearticles values(26-37% DM);, and from beginning to end of June as late harvest insert ignore into journalissuearticles values(≥38% DM);.
