Cherry tree named “B1218”

Abstract

A new and distinct sweet cherry tree (Prunus avium) named ‘B1218’ is disclosed. ‘B1218’ is characterized by early maturing, and a generally heart-shaped fruit that is dark in color.

Description

Genus and species: Prunus avium.

Variety denomination: ‘B1218’.

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

None

BACKGROUND AND ORIGIN OF THE NEW VARIETY

The new cherry cultivar that has been given the variety denomination ‘B1218’, was discovered in 2013 by inventor, as a whole tree cherry in an established orchard bloc of “Santina™” cultivar of cherry tree (not patented), on ‘Giesla 6’ rootstock (commonly referred to as ‘G6’) in a cultivated orchard, which was planted in 2010 and located at Zillah, Wash. The discovered mother tree of the naturally occurring sport ‘B1218’ is of unknown parentage, but assumed to be the ‘Santina’ cultivar.

Although the fruit of the ‘B1218’ mother tree was similar in color and shape to fruit from the ‘Santina’, the fruit on the ‘B1218’ mother tree matured five days to seven days after the ‘Santina’ cultivar's fruit. In 2016 this mother tree was genetically typed by the Foundation Plant Services of the University of California Davis, and discovered to be genetically different from ‘Santina’ and the forty-four other sweet cherry varieties on file. Second generation trees were grafted on ‘Giesla 12’ rootstock (commonly referred to as ‘G12’), and planted in 2017. Throughout several generations of asexual propagation, ‘B1218’ has been observed to retain its distinctive characteristics and to remain true to type.

SUMMARY OF THE NEW VARIETY

The present invention relates to a new a distinct variety of cherry tree Prunus avium, which has been given the variety denomination ‘B1218’. Specifically, ‘B1218’ is different from the “Santina™” cultivar of cherry tree (not patented) in that the bloom and the harvest maturity date of the ‘B1218’ is 5 days to 7 days later than the ‘Santina’ cultivar. Tree shape and bark of ‘B1218’ is similar to that of ‘Santina’. Most importantly, the genetic profile of ‘B1218’ does not match ‘Santina’, nor does it match other known sweet cherry genetic profiles. Fruit skin and flesh color is dark mahogany of ‘B1218’, as is ‘Santina’, but the fruit at harvest maturity of ‘B1218’ is firmer and sweeter than ‘Santana’ and has a slightly less acid level on average. Second generation trees of ‘B1218’ exhibit fruit identical that of the ‘B1218’ mother tree.

COMPARISON OF ‘B1218’ TO COMARISON CULTIVAR

Table 1., below, sets forth some of the distinguishing characteristics of ‘B1218’ as compared the ‘Santina’ cultivar, as a closely comparable cultivar. Firmness ratings listed in Table 1. were measured using a ‘Firm Tech 2’ brand of firmness tester, and the listed ratings are in milligrams needed to depress 1 millimeter. Measurements were taken at the same packing run date, as listed.

• Use: Desert. Excellent eating quality and premium fresh market.
• Resistance to insects and diseases: Susceptible to insects and diseases affecting cherries in the south central region of Washington State, where grown.
• Shipping and storage quality: Very good to excellent in conventional refrigeration.

Second generation trees of ‘B1218’ are uniform in all aspects. ‘B1218’ exhibits the herein above described characteristics as grown in Yakima County, in the south central region of Washington State. It is expected that differences may occur when grown in areas exhibiting different growing conditions.
