Definitions

  • the original tree is a seedling planted about 1948 in an avocado grove owned by me at the corner of Magnolia and Valley Streets in Carlsbad, San Diego County, California.
  • This avocado has a very distinct leaf shape, the leaves being dark green relatively slender, slightly crescent shaped and generally terminating in a relatively slender point.
  • the veins in the leaves are not particularly pronounced and taken as a whole the leaf has a uniform appearance.
  • the surfaces of the leaves which normally face upward and outward from the trunk of the tree are of a high gloss while the under surface has a fiat appearance.
  • the tree is found to be extremely resistant to frost damage. It has been observed that it will resist an ordinary frost temperature as low as 28 Fahrenheit which will harm other avocados and seems little affected by a mild frost.
  • the trees of this invention show a marked resistance to salt burn which makes it of particular desirability in coastal areas where salt burn frequently is a serious problem with other varieties.
  • This tree has been observed in a grove of trees of other varieties at Carlsbad, California.
  • the leaves of this tree remain virtually entirely green, while the varieties such as Fuerte, Nabal, Anaheim, and the like have leaves which turn brown and become brittle over a great portion of their surface, commencing from the tips.
  • the trees as they grow, bear extremely large quantities of relativelysniall fruit. Fruit is'spheroid in shape, averaging about 3 inches long and 8 to 10 ounces weight for each fruit. The trees bear large quantities economically marketable the second year after grafting. This results in early production from any grove.
  • the branches have a tendency to hang generally downward from the trunk and main branches contrary to a rather upward tendency towards the point of juncture which is exhibited by certain other varieties, notably the Nabal. This characteristic is important in that the branches dot not break under heavy loads as readily as would other varieties since there is a straight downward pull in the direction of growth which, of course, is quite resistant to breaking.
  • the fruit is characterized by a very high oil content; the oil content averaging in the neighborhood of 20%.
  • the California Avocado Society of Los Angeles, California analyzed fruit of this tree and found oil content 18.9%.
  • the fruit has smooth, firm, buttery flesh with a nutty taste and is characterized by its ability to stay upon the tree for relatively long periods after having reached maturity. By this particular character, it is possible for a grower to maintain fruit for many weeks in order to take best advantage of price conditions as they occur.
  • avocados have a tendency to alternatethat is, to bear heavy one year and light another year, or heavy one year and light for two years.
  • the avocado of this invention has proven itself to have a strong tendency to bear consistantly year after year and to have a strong tendency to eliminate the strong alternation found in many other varieties.
  • the skin is medium smooth, medium green color when mature, and it peels easily from the fiesh.
  • the green color is not an unusual green, but the customary green of several varieties of avocados such as Fuerte and Nabal, as distinguished from the dark purple of certain varieties such as Dickerson and Hass.
  • this avocado also, keeps well after harvesting for long periods thus making it possible to ship for long distances without danger of excessive loss.
  • the seed remains tight in the fruit until removed and is relatively small, weighing approximately of an ounce on the average.
  • the seed is, in general appearance, the same as most avocado seeds and the seed coat adheres tightly to the seed itself so that when removed from the fruit it is not necessary to scrape out the seed coat prior to eating.
  • Hass grows in a general tree shape somewhat similar to the Hass, but has green fruit, whereas the Hass is dark p p Bears heavily on limbs that hang generally downwardly from the major limbs or trunk, thus eliminating the tendency to break 01f.
