Description

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yodigit’.

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is co-pending with the following related applications: Title: Chrysanthemum Plant Named ‘Yoguide’. Applicant: Cornelis P. VandenBerg.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Yodigit’.

The new Chrysanthemum is a product of a planned breeding program conducted by the Inventor in Salinas, Calif. and Alva, Fla. The objective of the breeding program is to create new cut Chrysanthemum cultivars having inflorescences with desirable colors and good inflorescence form and substance.

The new Chrysanthemum originated from a cross-pollination made by the Inventor in May, 1995, in Salinas, Calif., of the Chrysanthemum×morifolium cultivar Alma, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum×morifolium identified as code number 1849, not patented, as the male, or pollen, parent.

The cultivar Yodigit was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Alva, Fla., in April, 1996. The selection of this plant was based on its desirable inflorescence color and good inflorescence form and substance.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in a controlled environment in Alva, Fla. since June, 1996, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Yodigit have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yodigit’. These characteristics in combination distinguish ‘Yodigit’ as a new and distinct cultivar:

• • 1. Upright cut Chrysanthemum that is usually grown as a natural spray.
  • 2. Dark green-colored foliage.
  • 3. Freely flowering habit, about ten inflorescences per flowering stem.
  • 4. Uniform inflorescence form and development.
  • 5. Small daisy-type inflorescences that are about 4.1 cm in diameter.
  • 6. Attractive white-colored ray florets.
  • 7. Response time about nine weeks.
  • 8. Strong peduncles.
  • 9. Good postproduction longevity with inflorescences and foliage maintaining good substance and color for about three weeks in an interior environment.

Compared to plants of the female parent, the cultivar Alma, plants of the new Chrysanthemum have slightly smaller inflorescences, are more freely and uniformly flowering and flower about three to four days later.

Compared to plants of the male parent selection, plants of the new Chrysanthemum have smaller inflorescences and are more freely flowering.

Compared to plants of the cultivar Yoguide, disclosed in U.S. Plant patent application Ser. No. 11/122,823, plants of the new Chrysanthemum differ primarily in ray floret coloration as plants of the cultivar Yoguide have bright yellow-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum×morifolium cultivar Vero, disclosed in U.S. Plant Pat. No. 6,399. In side-by-side comparisons conducted in Alva, Fla., plants of the new Chrysanthemum differed from plants of the cultivar Vero in the following characteristics:

• • 1. Plants of the new Chrysanthemum had smaller inflorescences than plants of the cultivar Vero.
  • 2. Plants of the new Chrysanthemum were more freely flowering than plants of the cultivar Vero.
  • 3. Plants of the new Chrysanthemum had shorter peduncles than plants of the cultivar Vero.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown in Salinas, Calif., under conditions which approximate commercial practice in a polyethylene-covered greenhouse. Two-week old rooted cuttings were planted on Dec. 30, 2004 and received about two weeks of long day/short nights followed by short day/long nights until flowering. Plants were grown as single-stem natural spray cut Chrysanthemums. During the production time, the following environmental conditions were measured: day temperatures, 24 to 27° C.; night temperatures, 10 to 16° C.; and light levels, 2,000 to 4,000 foot-candles. Measurements and numerical values represent averages for six to ten typical flowering stems and were taken about nine to ten weeks after the start of short days.
