Benefits of technology

It was found that the new variety of the present invention exhibits the following combination of characteristics: (a) exhibits a vigorous moderately-spreading upright growth habit, (b) is less alternate bearing than the `Hass` variety (non-patented in the United States) and fruits well every year, (c) forms ellipsoid-shaped generally black-skinned fruit that is well distributed around the tree which lacks shoulders, commonly is larger than that of the `Hass` variety, and matures at approximately the same time as the fruit of the `Hass` variety having yellow-green flesh of excellent eating quality that is free of obvious fibers, (d) forms leaves in greater quantity than the `Hass` variety that are similar in appearance to those of the `Hass` variety, and (e) displays moderate resistance to the Persea mite.

Problems solved by technology

Had the new variety not been discovered and carefully preserved it would have been lost to mankind.

Embodiment Construction

The following is a detailed description of the new `3-29-5` variety. The trees were being grown at experimental orchards of the University of California located at Irvine, Calif., were approximately six years of age, and had been grafted on Persea americana seedling understock. When reference to other varieties appears for comparative purposes, such varieties were approximately six years of age with the possible exception of the `Gwen` variety. The comparative trees of `Gwen` variety were mature and their exact age was unknown. Color chart information is with reference to The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. Tree: Growth habit.--Vigorous upright with moderate spreading. This can be compared to spreading for the `Hass` variety, moderately-spreading for the `Gwen` variety, and open and spreading for the `N4(-)5` variety. Height.--Approximately 4.5 m on average. This can be compared to an average height of 4.6 m for the `Hass` variety, 3.5 m for ...

Abstract

A new and distinct variety of Persea americana tree is provided. A vigorous moderately-spreading upright growth habit is exhibited. The tree is less alternate bearing than the widely-grown `Hass` variety (non-patented in the United States). The fruit is ellipsoid-shaped, lacks shoulders, is generally black-skinned, is well distributed around the tree, and commonly is larger than that of the `Hass` variety. The leaves are displayed in a greater quantity than the `Hass` variety and are similar in appearance to those of the `Hass` variety. Moderate resistance to Persea mites is exhibited. The variety is suitable for the production of quality avocado crop under commercial growing conditions.

Description

Botanical / commercial classification: Persea americana Mill. / Avocado Tree.Varietal denomination: cv. `3-29-5`.SUMMARY OF THE INVENTIONThe invention relates to new and distinct variety of Avocado tree that is named `3-29-5`.The seed that produced the new variety of the present invention was collected in 1985 from open-pollinated avocado trees of the `Gwen` variety (U.S. Plant Pat. No. 5,298) growing at Riverside and Irvine, Calif. The exact pollen parent is unknown. Seeds were planted in a test planting area at Ventura County, Calif. to produce avocado seedings in the spring of 1986. The resulting seedling plants were observed and studied and a single plant of the new variety was discovered. Had the new variety not been discovered and carefully preserved it would have been lost to mankind. During about 1992 at the Southcoast Research and Extension Center of the University of California located at Irvine, Calif., the new variety was first top worked by grafting on Persea americana seed...
