Description

BRIEF DESCRIPTION OF THE DRAWING

[0007] The accompanying photographic illustration in FIG. 1 illustrates in full color IFG Cher-seven. 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 can be seen in the upper portion of the drawing. Typical mature fruit, fruit in cross section and cleaned and dried fruit pits are displayed in the lower half of the drawing.

DETAILED BOTANICAL DESCRIPTION OF THE INVENTION

[0008] 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.

[0009] 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.

[0010] The descriptive matter which follows pertains to IFG Cher-seven plants grown in the vicinity of Delano, Kern County, Calif. during 2016, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere:
