Hass is one of the most important avocado cultivars produced in the world and Turkey. The aim of this study was to determine the most suitable fruit maturity standards for Hass cultivar by analyzing some physical and chemical parameters. The study was conducted at the two harvest periods from October to June in 2010-11 and 2012-13 years with 15-20 days intervals. Fruit weights changed from 106.73 g to 196.50 g in 2010-11 and from 98.45 g to 157.81 g in 2012-13 harvest periods. Dry weight of fruits increased from 19.60% to 36.45% and from 19.23% to 38.28% and oil content increased from 6.43% to 22.06% and from 6.47% to 24.86% depending on the harvest period in 2010-11 and 2012-13 respectively. There was a very high positive relationship between dry weight and oil content of fruit, but a significant negative correlation was found between fruit flesh and seed weight. As a result of this study; the optimal harvest period of Hass cultivar was determined to be from January to June in terms of fruit dry weight and oil content in Antalya conditions.
