Abstract

This invention is a new and distinct sweet cherry tree denominated ‘IFG Cher-two’. The new sweet cherry tree is characterized by producing large dark red fruits having broad shoulders and flat to round base. Fruits ripen early, about Apr. 14, 2014 in Delano Calif. The ‘IFG Cher-two’ has medium firm, medium acid fruit with a good cherry flavor. The tree has a medium low chilling requirement of approximately 300 to 500 hours. Fruits are tolerant of high summer temperatures and produce few doubled or spurred fruits.

Description

Latin name of the genus and species claimed: Prunus avium.
Variety denomination: ‘IFG Cher-two’.
BACKGROUND OF THE INVENTION
The new and distinct sweet cherry tree described and claimed herein originated from open pollinated seeds collected in May 2001. The female parent is an unidentified sweet cherry tree growing in a commercial orchard located near Bakersfield, in Kern County, Calif. The male parent is unknown. The seeds were stratified, germinated and the resulting one seedling was planted in a field near Delano, Kern County, Calif. in April 2002. The present variety of sweet cherry tree was selected as a single plant in May 2005 and was first asexually propagated in February 2009 by grafting onto Prunus mahalab rootstock. It was found to reproduce true-to-type by asexual propagation. All propagation was done near Delano, Kern County Calif.
BRIEF SUMMARY OF THE INVENTION
Sweet cherries have traditionally been grown in climates with long cold winters and cool to moderately warm summers. Such climates provide enough cold winter temperatures to allow normal growth to resume in the spring and summer temperatures that are low enough not to induce production of unmarketable double or spurred fruit, but it limits the seasonality that cherries are available. The sweet cherry breeding program focuses on developing types of cherries that will grow in regions with low winter chilling and high summer temperatures so that the fruit will ripen before fruit in traditional growing regions.
The new sweet cherry tree ‘IFG Cher-two’ is characterized by producing large dark red fruits having broad shoulders and flat to round base. Fruits ripen early about three to five days ahead of the ‘Brooks’ variety (U.S. Plant Pat. No. 6,676). The ‘IFG Cher-two’ has medium firm, medium acid fruit with a good cherry flavor. The tree has a medium low chilling requirement slightly lower than the ‘Brooks’ variety. It produces fewer doubled and spurred fruits as compared to the ‘Brooks’ variety in high summer temperature regions such as the Southern San Joaquin Valley of Calif. Fruits of ‘IFG Cher-two’ have medium long, thick stems that remain attached and stay green during storage and shipping.
In comparison to the ‘Brooks’ variety, which is a major variety grown in warm regions, the present variety ripens about three to five days earlier and has more desirable darker red skin and flesh. It also has fewer undesirable doubled and spurred fruits as compared to ‘Brooks’ and has superior storage characteristics. In comparison to its female parent, the present variety has larger, firmer fruits. In comparison to the ‘Tulare’ variety (U.S. Plant Pat. No. 6,407), the ‘IFG Cher-two’ produces larger fruit that ripen approximately six to eight days before the ‘Tulare’ variety. The fruit shape of ‘IFG Cher-two’ has a more desirable flat-rounded shape with broad shoulders and flat stylar end compared to the more pointed, narrower shoulder shape of the ‘Tulare’ variety.
BRIEF DESCRIPTION OF THE DRAWING
The accompanying photographic illustration in FIG. 1 illustrates in full color ‘IFG Cher-two’, taken from a 12-year old tree. The photograph was taken outdoors with indirect lighting. The colors are as nearly true as is reasonably possible in a color representation of this type. An actively growing shoot tip collected at harvest can be seen in the upper portion of the drawing. Typical nature fruit and fruit in cross-section are displayed on the lower half of the drawing. Typical cleaned and dried fruit pits are displayed on the lower half of the drawing.
 DETAILED BOTANICAL DESCRIPTION OF THE INVENTION
Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. Color names beginning with a capital letter designate values based upon R.H.S. Colour Chart, published in 2001 by The Royal Horticultural Society, London, England.
Throughout this specification subjective description values conform to those set forth by the International Board for Plant Genetic Resources (IBPGR) ‘Cherry Descriptor List’ (Prunus spp.) (1985) which was developed with full support from the Commission of the European Communities (CEC) Programme Committee for Plant Disease Resistance Breeding and the Use of Genebanks.
The descriptive matter which follows pertains to an ‘IFG Cher-two’ plant growing on its own roots in the vicinity of Delano, Kern County, Calif. during 2013 to 2014, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere:
