- Patented Aug. 24, 1937 AVOCADO Joseph R. Byrum, Homestead, Fla., assignor to Redland Avocado Grove, Homestead, Fla.
- My discovery relates to a new and distinct variety of the avocado fruit, having certain desirable characteristics among which may be mentioned the following:
- the fruit is unusual in size compared with any other known winter variety of avocado
- the flesh is free from fiber, and of distinctive coloring
- the color and texture of the skin is distinctive and attractive in appearance
- the tree is an unusually vigorous upright grower, well branched with distinctive foliage.
- Fig. 1 is a side elevational view in color of the fruit when ripe
- Fig. 2 is a longitudinal section of the fruit of Fig. 1;
- Fig. 3 is a perspective view in color of the leaves with their petioles.
- Fig, 4 is a fragment taken from the exterior surface of the avocado, showing in black and white the slightly protuberant formations on the skin of the fruit.
- the original tree was found as a sapling which grew on a tract of land comprising part of the Redland Avocado Grove, located at Homestead, Florida.
- the sapling came up under a Waldin tree about two feet from the trunk, and was first discovered in January, 1935, being about three years old at that time.
- the tract in which the sapling was first discovered comprises about ten acres, and in this tract there were principally Waldins and a few saplings of West Indian race or type; of Guatemalan origin, there were a number of Schmidt variety, one Eagle Rock, also four of Taft variety.
- the new avocado is therefore probably a cross between the West Indian and Guatemalan types of avocado.
- the method of grafting is to saw a tree down, saw across the stump, open stump with a wedge, insert two grafts, remove wedge and cover with grafting wax, tie stiff paper around the stump, and then cover the stump with three inches of sand; getting close to one hundred per cent success.
- the parent tree has just been transplanted to where it can be better observed and to prevent it from killing the Waldin.
- the fruit weighs from twenty-six to thirty-six ounces when mature, varying in size from five and one-half to six inches in length and four to four and one-half inches in width.
- the skin is dark green in color (about 21L12 of Maerz and Paul) with a glossy speckled surface.
- the flesh is free from fiber and is of a clear bright yellow color (about L2), slightly green (about 19L2) near the skin.
- the seed is tight and generally round in shape.
- the oil content runs between 10 and 30%, and the flesh has an excellent nutty flavor.
- the tree is an unusually vigorous upright grower, and varies from a good to a heavy producer.
- the fruit matures during the months of December, January and February.
- the tree is of medium height, well branched and has distinctive foliage (upper side about L1underside about 131-11).
- the new avocado tree belongs in the A pollination group; it is decidedly resistant to scab, and in fact it has been found of a hardier and more robust growth than other known prior varieties of this general type.
- the winter variety of avocado substantially as herein disclosed, characterized by the trees Vigorous growth, fruits size, texture and color, and the distinctive foliage.
