Abstract
A new and distinct cultivar of peach tree, denominated ‘Cardinal Joy’, has firm, melting, semi-freestone fruit with a high coverage of red blush, yellow flesh, normal acidity, rich flavor and pleasant eating quality at maturity. The fruit typically ripen about a week after ‘Flavorich’ (syn. ‘Rich May’) and a few days before ‘Carored’ in mid to late May at Byron, Ga. The tree has self-fertile showy pink flowers and is moderately vigorous and semi-spreading in growth habit. This cultivar has a winter chilling requirement of approximately 850 chill hours, crops well most years, and is suited for high chill areas.
Description
Latin name of the genus and species of the plant claimed: ‘Cardinal Joy’ is a new tree of peach with the Latin name of Prunus persica (L.) Batsch.
Cultivar denomination: The new peach tree is denominated ‘Cardinal Joy’.
The present invention relates to a new and distinct peach cultivar designated ‘Cardinal Joy’, botanically known as Prunus persica (L.) Batsch, and tested as BY02P3726 obtained from a hand-pollinated cross between BY93P3635 (an advanced selection, unpatented, the seed parent) and ‘Rich Joy’ (patented: U.S. Plant Pat. No. 31,081, the pollen parent) yellow peaches. Fruit of ‘Cardinal Joy’ ripen approximately 28 days before ‘BY93P3635’ and 54 days earlier than ‘Rich Joy’. This new peach tree is adapted to a Southeastern subtropical climate with high chill in winters. Its high chilling requirement (˜850 chill hours) and desired early ripening season make it worthy of commercial production trials for the fresh fruit market. Clonal plants were asexually propagated from the original ‘Cardinal Joy’ tree by grafting on ‘Guardian’® peach seedling rootstocks in Byron, Ga. These asexually propagated plants, along with all characteristics of the tree and the fruit, remained true-to-type to the original ‘Cardinal Joy’ tree. There are no known effects of the standard rootstock on the scion cultivar characteristics.
‘Cardinal Joy’ produces firm, melting, semi-freestone, yellow-flesh fruit with normal acidity, rich flavor, attractive red skin color (blush) and yellow background, which ripens in mid to late May in Byron, Ga. ‘Cardinal Joy’ is a promising candidate for commercial success in the early harvest season in that it has a high chilling requirement and crops very well with attractive, rich-Cardinal fruit.
Byron, Ga is under a subtropical climate. Winters are short, mild and with little snow; summers are long, hot and humid. The average January low temperature is about 1.2° Celsius (34.2° Fahrenheit) and the average July high temperature is about 33.2° Celsius (91.8° Fahrenheit). The hours with temperatures below 7.2° Celsius (45.0° Fahrenheit) vary between 600 and 1200 hours per year. There are about 67 rainy days per year. Average annual precipitation (rainfall) is 1182.9 millimeters (46.6 inches) with great monthly and yearly variabilities and frequent thunderstorms in summers.
The new and distinct cultivar ‘Cardinal Joy’ peach tree blooms mid to late March, approximately with ‘Elberta’ (unpatented) peach trees in Byron, Ga. The estimated chilling requirement, based on bloom time, is approximately 850 chill hours. The blooming period and the blooming date are dependent on climatic conditions. The flower anthers are yellow, and leaf glands are reniform, characteristic of many standard peach cultivars.
The first fruit of ‘Cardinal Joy’ ripen generally in mid to late May (the early season) in Byron, Ga., approximately a week after ‘Flavorich’ (syn. ‘Rich May’, patented: U.S. Plant Pat. No. 7,432) and a few days before ‘Carored’ (unpatented). ‘Cardinal Joy’ fruit tend to have rich flavor and approximately 90% red skin (more than ‘Flavorich’ fruit that have ˜60%). ‘Cardinal Joy’ trees are productive and crop reliably. The potential for commercial production of fresh ‘Cardinal Joy’ fruit is high because it is one reliable higher-chill alternative (˜850 chill hours) that ripens during the harvest seasons of ‘Flavorich’ (˜700 chill hours) and ‘Carored’ (˜650 chill hours) that bloom earlier and thus usually incur higher risk of crop loss to spring freeze.
The accompanying drawings are color photographs that are taken at Byron, Ga. and as nearly true as it is reasonably possible to make in a color illustration of this type:
Due to light, exposure, and other photographical parameters and technologies, the leaves and fruit depicted in these photographs may or may not be accurate when compared to the actual botanical specimen.
The tree, flowers, fruit, and other botanical parts may vary in slight detail due to variations in climatic conditions, cultural practices, development stages, growing seasons, soil types, and tree ages. Referring more specifically to the detailed botanical description of this new and distinct cultivar of yellow-flesh peach tree, the following was observed on 12-year-old trees of the cultivar grafted on ‘Guardian’® rootstock under the ecological conditions prevailing at the orchards located at the town of Byron, Ga., USA. All major color code designations are by reference to The Great Britain Royal Horticultural Society (R.H.S.) Colour Chart (Fourth Edition).
- Tree:
-
- Bearer.—Regular. The fruit must be thinned to obtain large fruit size and avoid limb breakage.

- Form.—Semi-spreading, but easily pruned to vase shape.
- Hardiness.—Hardy with respect to typical GA winters.
- Productivity.—Very productive and regular, every year. Fruit set is reduced by thinning to develop the remaining fruit into desired market size. The fruit number varies with the prevailing climatic conditions and cultural practices.
- Size.—Generally considered large when trained to an open vase form. The height and width of 12-year-old annually pruned tree are 3.2 meters and 4.5 meters, respectively, including current season shoots.
