Abstract

The present invention relates to an almond tree, botanical classification Prunus dulcis cultivar ‘MARCHINI’, and more particularly to a new and distinct variety broadly characterized by a large size, vigorous, hardy, self-sterile, productive and regular bearing tree whose nuts mature under the ecological conditions described approximately the last week in August. The nut is medium in size and is enclosed by a soft, open shell that is easily removed by hand or by machanical shellers. The shelled nut may be marketed as a whole, blanched, sliced or diced product. The inshell nut is very suitable as a roasted and salted product.

Description

BOTANICAL CLASSIFICATION
Prunus dulcis cultivar ‘MARCHINI’.
BACKGROUND OF THE VARIETY
The present invention relates to a new and distinct variety of almond tree, Prunus dulcis, which has been denominated varietally as “MARCHINI”. The variety was discovered by me in 1962 as a chance seedling in a cultivated area of my property located at 1435 South Cook Street in the town of Le Grand, Calif., in Merced County (San Joaquin Valley). This seedling was one of many to sprout following the removal of a ‘Nonpareil’ (unpatented), ‘Davey’ (unpatented), and ‘Neplus’ (unpatented) planting. A row of these seedlings was purposely left along the edge of the property to form a natural barrier, and this particular tree stood out during the first few years for heavy production. Subsequent to the discovery of the present variety of almond tree, I asexually reproduced it by budding and grafting in my almond orchard located one mile from the discovery site, and such reproduction of plant and fruit characteristics were true to the original plant in all respects. Over the years further reproductions by budding were made in my orchard located at 11986 East Le Grand Road, Le Grand, Calif., for continued testing and evaluation purposes. These reproductions of the variety included the use of ‘Nemaguard’ (unpatented) and ‘Lovell’ (unpatented) rootstocks upon which the present variety was compatible and true to type.
I originally tested and selected the present variety because of its heavy production and its potential to pollinate ‘Nonpareil’ (unpatented), blooming about 3 days later than ‘Nonpareil’. With the emergence of the ‘Carmel’ (U.S. Plant Pat. No. 2,641) as a prominent commercial variety in California, the value of the present variety as a pollinator and co-planter with both ‘Nonpareil’ and ‘Carmel’ became substantial. During the last few years the demand for an almond suitable for marketing as a roasted, salted, inshell product has substantially increased. The present variety is perfectly suited for this purpose, as it has a very soft shell for easy hand removal and an open shell to facilitate the salting process.
The present almond variety is most similar to ‘Nonpareil’ (unpatented) by being a relatively early blooming variety that produces light colored nuts enclosed in a soft shell, but is distinguished therefrom and an improvement thereon by having a smaller nut, by harvesting one week later, by being more productive, by appearing to be free of bud-failure, and by being interfertile with both ‘Nonpareil’ and ‘Carmel’ (U.S. Plant Pat. No. 2,641).
DRAWING
The accompanying color photograph exhibits nuts in hull, nuts out of hull, kernels out of shell, and leaves, all typical of the instant variety.
POMOLOGICAL CHARACTERISTICS
Referring now more specifically to the pomological characteristics of this new and distinct variety of almond tree, the following has been observed under the ecological conditions prevaling near Le Grand, Merced County (San Joaquin Valley), Calif., and was developed at the harvest stage on Aug. 25, 2001. All major color code designations are by reference to the Inter-Society Color Council, National Bureau of Standards. Common color names are also used occasionally.
