The Hass avocado is a large-sized fruit weighing 200 to 300 grams. When ripe, the skin becomes a dark purplish-black and yields to gentle pressure. When ready to serve, it becomes white-green in the middle part of the inner fruit.
Owing to its taste, size, shelf-life, high growing yield and in some areas, year-round harvesting, the Hass cultivar is the most commercially popular avocado worldwide.
Hass avocado trees, like some other cultivars, may only bear well every other year. After a year with low yield, often because of cold, for which the tree does not have much tolerance, yields may be very high the next year. However, the heavy crop can deplete stored carbohydrates, lowering the following season’s yield and this can set the tree into a lifelong alternate bearing pattern.
