ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Marguerite Daisy plant, botanically known as
Argyranthemum frutescens
and referred to by the cultivar name Lemon Delight.
The new cultivar is a product of a planned breeding program conducted by the Inventor in Emerald, Victoris, Australia. The objective of the breeding program was to develop new Marguerite Daisies that are heat-tolerant.
The new cultivar originated from a cross made by the Inventor in 1994 of the
Argyranthemum frutescens
cultivar Frosty, not patented, as the male or pollen parent, with the
Argyranthemum frutescens
cultivar Harvest Snow, not patented, as the female or seed parent. The cultivar Lemon Delight was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Emerald, Victoria, Australia.
Plants of the new Marguerite Daisy are different from plants of the male parent, the cultivar Frosty, in growth habit, inflorescence color and size and tolerance to high temperatures and humidity.
Plants of the new Marguerite Daisy are different from plants of the female parent, the cultivar Harvest Snow, in growth habit, leaf color and size, and inflorescence color and size.
Asexual propagation of the new cultivar by terminal cuttings in Emerald, Victoria, Australia, has shown that the unique features of this new Marguerite Daisy are stable and are reproduced true to type in successive propagations.
SUMMARY OF THE INVENTION
The new Marguerite Daisy has 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 characteristics have been repeatedly observed and are determined to be basic characteristics of ‘Lemon Delight’ which distinguish ‘Lemon Delight’ as a new and distinct cultivar:
1. Rounded, spreading and mounding plant habit; compact; freely branching, dense and bushy plants with short internodes and numerous leaves.
2. Freely flowering with numerous inflorescences per plant held beyond the foliage.
3. Large single-type inflorescences.
4. Lemon yellow ray florets and dark yellow disc florets.
5. High temperature and humidity tolerance.
Plants of the new Marguerite Daisy can be compared to plants of the nonpatented commercial cultivar Harvest Gold. In side-by-side comparisons conducted in Emerald, Victoria, Australia, plants of the new Marguerite Daisy have lighter green leaves, lighter yellow ray florets and are more high temperature and humidity tolerant than plants of the cultivar Harvest Gold.
Plants of the new Marguerite Daisy can also be compared to plants of the cultivar Midas Gold (U.S. Plant patent application Ser. No. 09/263,151). In side-by-side comparisons conducted in Emerald, Victoria, Australia, plants of the new Marguerite Daisy are different from plants of the cultivar Midas Gold in ray and disc floret color and leaf shape.
