'Yowoodstock' has more ray florets and they are narrower than those of the reference variety. 'Yowoodstock' has a smaller disc than 'White Yograceland'. The mature disc florets of 'Yowoodstock' are yellow green at the apex, whereas those of 'White Yograceland' are yellow.

Description: 'Yowoodstock' is disbud type chrysanthemum variety which has plants that are medium in height with a medium number of primary lateral shoots. There is no anthocyanin on the stems. The leaves are long and broad. The base of the leaf is a broad wedge. The lower lobe of the leaf is medium to long, with a moderately deep sinus. The margins of the sinus between the lateral lobes are parallel.

'Yowoodstock' has anemone type flower heads, which are white. The flower heads are large to very large in diameter. There are no bracts among the florets. The ray florets are long, reflexing and have a short corolla tube. In cross section the ray florets are concave, and have an emarginate or dentate tip. The disc of 'Yowoodstock' is large to very large in diameter and green before anther dehiscence. The disc florets are tubular and enlarged, numerous and mostly massed at the centre. There are petaloids present.

Origin & Breeding History: 'Yowoodstock' is the product of a planned breeding program conducted by the breeder, an employee of Yoder Brothers, Inc. The variety originated from a cross made in June 1998, in Salinas, California. The female parent was a proprietary Chrysanthemum seedling identified as YB-5721. The proprietary seedling YB-4609 was the male parent. A single flowering plant was selected from within the progeny of the cross in March 1999, in a controlled environment in Fort Myers, Florida. The selection of this plant, which became the variety 'Yowoodstock', was based on uniform plant growth habit, desirable inflorescence form and floret colours, fast response time and excellent postproduction longevity. Asexual reproduction of 'Yowoodstock' was first conducted in Fort Myers, Florida, in June 1999.

Tests & Trials: Tests and trials for 'Yowoodstock' were conducted at Yoder Canada Ltd., Leamington, Ontario, in the fall of 2005. Flowering trials were performed under greenhouse conditions similar to those used in commercial production. On August 8, 2005, unrooted cuttings of the candidate and reference varieties were directly stuck into 15cm pots, with 4 cuttings per pot and 10 pots per variety. Plants were pinched once prior to short day treatment. All plants were disbudded. Pots were spaced 12 inches apart. Observations and measurements were taken from 10 plants of each variety on November 3, 2005. All colour measurements were made using the RHS Colour Chart 2001.
