USPP29049P3 - Cherry tree named ‘SMS-9CA 2014-9’ - Google Patents

Abstract

A new and distinct variety of sweet cherry tree, which is denominated varietally as ‘SMS-9CA 2014-9’, and which produces fruit having an early ripening fruit (‘Chelan’ timing), and which further has a large fruit, high production, self-fertility, a long stem, and strong fruit attachment, and which further has a very attractive appearance, and organoleptic qualities.

Description

Latin name: Prunus avium L.

Varietal denomination: SMS-9CA 2014-9.

BACKGROUND OF THE INVENTION

The new variety was discovered from an open pollination of seeds collected from a proprietary sweet cherry selection ‘SC3-35’ (unpatented), and which was located near Vina, Lodi, and Bakersfield, Calif. in 1998. The seeds stratified, testa removed, and then were germinated and planted in pots in 1999. After germination, the aforementioned seeds were grown in pots for 3 years until flowering. Fruit was first observed in 2002. A first asexual propagation took place when buds were taken in that same year and propagated on the Prunus mahaleb rootstock (unpatented) for further confidential trials, and which were conducted in Vina, Calif., and Spain starting in 2003. After two years of cropping in pots, buds were taken in a second asexual reproduction and grafted onto Prunus mahaleb rootstock for further evaluation in Stockton, Calif. in 2004. Additional confidential trials similar to that which are described, above, were conducted starting in 2006 in Stockton, Calif., and in 2009 in Roosevelt, Wash. In 2007, the first fruit from trial growing fields were then evaluated.

Throughout the aforementioned trials and various asexual propagations, the tree and fruit produced thereby were compared to the originally discovered plant. All characteristics of the original tree, and its fruit were established, and appears to have been transmitted to the aforementioned succeeding generations.

SUMMARY OF THE INVENTION

The variety ‘SMS-9CA 2014-9’ is an early ripening cherry tree selection which matures with or slightly after the ‘PC 7146-23’ cherry tree variety (U.S. Plant Pat. No. 8,545, hereinafter referred to by its trade name ‘Chelan’) in Washington State; and with or slightly later than the ‘Brooks’ Cherry Tree (U.S. Plant Pat. No. 6,676) which are growing in California. ‘SMS-9CA 2014-9’ is distinct from the aforementioned, well known varieties because the fruit it produces is larger, and the tree is more productive than either the ‘Chelan’ or ‘Brooks’ Cherry trees. It is believed that the self-fertile alleles S₁S_4′ help to insure regular cropping as compared with the self-infertile Cherry cultivars ‘Chelan’ and ‘Brooks’ which require cross-pollination. The organoleptic qualities of the fruit are superior to the fruit produced by ‘Chelan’ as well, and is highly appreciated by those consuming the fruit. The fruit size can average 25-28 mm in diameter as compared with 22-24 mm for the fruit produced by ‘Chelan’ Cherry Tree even though the crop is much larger. Many fruit of the new variety can be in the 32 to 36 mm size range. The fruit produced by the ‘Chelan’ Cherry tree reached harvest maturity in the first to second week of May under the ecological conditions prevailing near Stockton Calif. The cherry of the new variety is dark red (CTIFL, color codes 4 and 5) (Centre Technique Interprofessional des fruit et legumes) at harvest, and a deep purplish color (CTIFL 6 color code) at full maturity. The firmness of the fruit is comparable to the fruit of the ‘Chelan’ Cherry Tree with a tendency toward being slightly less firm because of the large cropping potential of the new variety.

The present, new variety is distinguishable from the ‘SC3-35’ cherry tree variety (the parent), in view of its higher and more regular fruit production per tree, when compared to the fruit production of the ‘SC3-35’ cherry tree. Further, the present, new variety is distinguishable from the ‘SC3-35’ cherry tree in view of the fruit it produces, which possesses a larger fruit size than the fruit produced by the ‘SC3-35’ cherry tree. Still further, the present, new variety is distinguishable from the ‘SC3-35’ cherry tree (the parent) in view of the fruit it produces, which possesses an earlier ripening date than the fruit produced by the ‘SC3-35’ cherry tree. Moreover, the present, new variety is distinguishable from the ‘SC3-35’ cherry tree (the parent) in view of the fruit it produces, which possesses longer stem length relative to the fruit produced by the ‘SC3-35’ cherry tree.

• Relative fruit size: At harvest maturity, and when grown under similar ecologic conditions, the new variety produces fruit having a mean size 27 mm, as compared to the fruit of the ‘Chelan’ Cherry Tree (21.9 mm); and the ‘Brooks’ Cherry Tree (24.1).
• Relative cracking: In comparison to the fruit produced by either the ‘Chelan’ or ‘Brooks’ Cherry Tree, the relative amount of cracking is lower, and is about 6%.

Although the new variety of cherry tree possesses the described characteristics when grown under the ecological conditions prevailing near Lodi and Stockton, Calif., it should be understood that variations of the usual magnitude, and characteristics incident to changes in growing conditions, fertilization, nutrition, pruning, pest control, frost, climate variables and changes in horticultural management are to be expected.
