Abstract

The new variety of Cherry Tree, named `Brooks`, produces early-maturing fruit of very high quality which is very large, symmetrical and uniform in size. The fruit ripens about one week after `Early Burlat`, and about one week prior to `Bing`. The fruit is also characterized by having a fruit quality and firmness superior to `Early Burlat` and sweet, well balanced rich flavor which is exceptional for early season maturity.

Description

DESCRIPTION
This invention relates to a new variety of cherry tree, named `Brooks`, which is the result from the cross of the cherry cultivars known as `Ranier` and `Early Burlat` made in 1969.
Selection 12-28, a seedling of the cross, was planted in February of 1970 and the fruit of the selection was first obsserved in 1976. Selection 12-28 was then planted at the University of California. Wolfskill Ranch at Winters, Calif., and in 1978 was asexually reproduced by bud grafting. Selection 12-28, named `Brooks` has been tested in a number of locations and evaluated. The evaluation revealed the merit of this new variety of cherry tree and resulted in its selection as a promising cultivar.
The characteristics that distinguish `Brooks` are its very high quality, early maturing fruit and outstanding ability to develop uniformly and exceptionally large size fruit. The fruit is quite symmetrical and ripens evenly about one week prior to the popular `Bing` variety (unpatented). In comparison with `Early Burlat`, the fruit of `Brooks` is larger, of higher quality and superior firmness. `Brooks` has a flavor which is sweet, well-balanced and exceptional for early season maturity. The tree has demonstrated its ability to perform well in the warmer areas of the State of California.

FIG. 2 illustrates the flesh color and fibers of the fruit when cut in transfer section;
FIG. 3 illustrates a cluster of fruit and leaves typical of the new variety and
FIG. 4 illustrates mature leaves which are typical of the new variety.
The following specific description is of plant material obtained from a ten year old bearing cherry tree located in a test selection block at the University of California, Kearney Agricultural Center, Parlier, Calif. The fruit is described at firm maturity. Color definitions are from "Dictionary of Color" by Maerz and Paul, published in 1950.
