The Hass avocado or Hass avocado are the common names of the Persea americana fruit belonging to the "Hass" variety, originated from a Guatemalan seed in an orchard of Rudolph Hass in the Habra, California in 1926, patented in 1935 and introduced globally in the market in 1960; It is the most cultivated variety in the world.
The Hass variety has an oil content that ranges between 8 and 12%. In addition, the proportion of water is low, of only 60-70%. Its content of B vitamins and vitamin E is considerable.
Both the fruit and the seed are relatively small, with a combined weight between 200 to 300 g. The skin is somewhat leathery, rough, green to slightly blackish when on the tree; once harvested, it becomes violaceous to black as the fruit softens when it ripens, so the consumer recognizes the optimum moment to consume it.
The fruit is of excellent quality, without fiber, high resistance to transport and long post-harvest life.
In general, the tree of this variety blooms only once a year, from early to mid-spring and, depending on the variety and thermal accumulation of the place, it can take between 6 and 11 months to mature. The Hass variety, especially in cool climates, can be maintained in the tree once mature, for several months without major apparent deterioration, which allows to extend the harvest period enormously.
