Orchid named ‘HONEY MICHELL’

Abstract

A new and distinct variety of Oncidesa plant denominated ‘HONEY MICHELL’ which is with varied floral colors of white, whitish, yellow and yellowish, compared to the parent variety, i.e. HONEY ANGEL. HONEY ANGEL has yellow flowers. The height of HONEY MICHELL is about ⅔ to half to the height of the parent variety, HONEY ANGEL. Therefore, the generated new variety is suitable for the pot plant usage in the oncidium flower market. Compared to other similar dwarf oncidium hybrid orchids, which are planted and sold as ornamental pot orchids, such as Oncidium ‘Twinkle’ or Oncidium ‘Sepia’, they are only similar in plant height, around 50˜70 cm height. The floret size is tiny and floret number is crowded with Oncidium ‘Twinkle’. In contrast, the floret size of ‘HONEY MICHELL’ is bigger (3˜5 cm width), and floret number is relatively few.

Description

Botanical classification: Oncidesa Gower Ramsey.

Variety denomination: ‘HONEY MICHELL’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety from the parent orchid, Oncidesa Gower Ramsey ‘HONEY ANGEL’. The new variety has been given the variety denomination ‘HONEY MICHELL’. This orchid's offspring is variated with different floral colors of white, whitish, yellow and yellowish, even though by using asexual propagation. The ‘HONEY MICHELL’ is usually dwarf, compared to its parent variety, and this new derived variety of Oncidesa was stable and persistent growing.

ORIGIN OF THE VARIETY

The current novel variety, i.e. ‘HONEY MICHELL’ is derived from the parent variety, i.e. Oncidesa Gower Ramsey ‘Honey Angel’ during the asexual tissue culture propagation process. While the Oncidesa Gower Ramsey ‘Honey Angel’ was asexually propagated by protocorm-like body (PLB) tissue culture technology, the plant hormone concentrations of culture medium were changed to higher dose, and there are few varied morphological seedlings appearing in the cultural mediums. Among the aforesaid varied seedlings, some show dwarf size and paler green leaf color after a period growth than parent seedlings. Then, such varied seedlings were isolated and grew to mature, and their flowers display white or light yellow or yellowish, and dwarf (lower height). Herewith, it is named Oncidesa ‘HONEY MICHELL’. The tissue culture work was carried out from 2020 to 2021.

The somatoclonal variation of ‘HONEY MICHELL’ was caused by chemical-induced mutation, through the addition of the hormone NAA/BA at a dosage of 0.5˜2.5 ppm/0.1˜1 ppm to the conventional growth MS medium (½ Murashige and Skoog medium base, coconut juice 150 ml/L), MS medium contains major salts, minor salts and vitamins chemicals. Macronutrients per litre are composed of Ammonium nitrate (NH₄NO₃) 1650 mg/l, Calcium chloride (CaCl₂·2H₂O) 440 mg/l, Magnesium sulfate (MgSO₄·7H₂O) 370 mg/l, Monopotassium phosphate (KH₂PO₄) 170 mg/l and Potassium nitrate (KNO₃) 1900 mg/l. Minor salts are composed of Boric acid (H₃BO₃) 6.2 mg/l, Cobalt chloride (CoCl₂·6H₂O) 0.025 mg/l, Ferrous sulfate (FeSO₄·7H₂O) 27.8 mg/l, Manganese(II) sulfate (MnSO₄·4H₂O) 22.3 mg/l, Potassium iodide (Kl) 0.83 mg/l, Sodium molybdate (Na₂MoO₄·2H₂O) 0.25 mg/l, Zinc sulfate (ZnSO₄·7H₂O) 8.6 mg/l, Ethylenediaminetetraacetic acid ferric sodium (FeNaEDTA) 36.70 mg/l and Copper sulfate (CuSO₄·5H₂O) 0.025 mg/l. Vitamins and organic compounds per litre are composed of Myo-Inositol 100 mg/l, Nicotinic Acid 0.5 mg/l, Pyridoxine·HCl 0.5 mg/l, Thiamine·HCl 0.1 mg/l, Glycine 2 mg/l, Tryptone 1 g/l (optional). The generation of ‘HONEY ANGEL’-derived variety, ‘HONEY MICHELL’, was repeated for three times at least, and the outcome is reproducible.

After protocorm-like bodies (PLB) were cultivated, propagated and shooting in the supplemented medium for 2˜3 months in 8/16 hr (dark/light) at 22° C., approximately one third of the shoots appeared pale green. These shoots were selected, subcultured in fresh MS medium with the same concentration of NAA/BA as the previous medium recipe and grown up to seedlings. The mature seedlings were subsequently moved out to grow in pot and cultivated in a green house until mature plants growing-up.

The technology can generate variated progenies with different floral colors of white, whitish, yellow and yellowish, compared to the parent variety, ‘HONEY ANGEL’, which is bright yellow. In addition, the ‘HONEY ANGEL’-derived variety plants are usually dwarf, compared to the parent variety. This new Oncidesa ‘HONEY ANGEL’-derived variety, ‘HONEY MICHELLI’ is stable and persistent growing.

SUMMARY OF THE VARIETY

The new and distinct variety ‘HONEY MICHELL” orchid has the following outstanding and distinguishing characteristics. The major differences between the new Oncidesa ‘HONEY MICHELL’ compared with the parent variety include characteristics of flower color, plant height and early-flowering time. The mature plant height of the new Oncidesa ‘HONEY MICHELL’ variety is about ⅔ to half of the height of the parent variety, ‘Honey Angel’ and other Oncidesa varieties. Therefore, the ‘HONEY MICHELL’ is suitable for the ornamental pot orchids in the oncidium flower market.

DESCRIPTION OF THE DRAWINGS

This new Oncidesa plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds, and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken on August, 2021. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 1 and FIG. 2 show that the flower color of the Oncidesa ‘HONEY MICHELL’ is light yellow or yellowish.

FIG. 3(A) shows the mature plant height of this Oncidesa ‘HONEY MICHELL’.

The florescent tip of the new Oncidesa variety is round tip, while the florescent tip of the parent variety and other Oncidesa varieties are comparatively sharp.
