Description

Genus and species: Chaenomeles speciosa.

Variety denomination: ‘Scarlet Storm’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of flowering quince, botanically known as Chaenomeles speciosa, and hereinafter referred to by the cultivar name ‘Scarlet Storm’. This new flowering quince was developed through a breeding program at North Carolina State University, Mills River, N.C. ‘Scarlet Storm’ is an F1 hybrid between the female parent, Chaenomeles speciosa ‘Spitfire’ (unpatented) and the male parent, Chaenomeles speciosa ‘Dragons Blood’ (unpatented). The first asexual propagation of ‘Scarlet Storm’ was carried out in June 2003 by rooting stem cuttings at the North Carolina State University, Mountain Horticultural Crops Research Station, Mills River, N.C. and has been asexually reproduced repeatedly by vegetative cuttings in North Carolina over a five year period.

‘Scarlet Storm’ roots readily from softwood cuttings treated with a basal dip of 5,000 ppm indole butyric acid (potassium salt) in water. ‘Scarlet Storm’ has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this cultivar have not been applied for. ‘Scarlet Storm’ has not been made publicly available more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices at North Carolina State University, Mountain Horticultural Crops Research Station, Mills River, N.C.

    • 1. A medium-sized, upright, multi-stemmed, fruitless shrub;
    • 2. Large, double-flowers with scarlet-red petals; and
    • 3. Thornless stems.

DESCRIPTION OF THE PHOTOGRAPHS

This new quince plant is illustrated by the accompanying photographs which show the plant's form, foliage and inflorescences.

COMPARISON WITH PARENTAL LINES AND KNOWN CULTIVARS

‘Scarlet Storm’ is distinguished from the female parent, Chaenomeles speciosa ‘Spitfire’ (unpatented) in that ‘Scarlet Storm’ has 17–25 petals, flowers without pistils, is thornless and lacks fruit, while ‘Spitfire’ has 5 petals, flowers with pistils, has some thorns on the stems and produces fruit.

‘Scarlet Storm’ is distinguished from the male parent, Chaenomeles speciosa ‘Dragons Blood’ (unpatented) in that ‘Dragons Blood’ generally has fewer and smaller (less than 5 cm in diameter) flowers.

Table 1 shows the differences between ‘Scarlet Storm’ and commercial varieties ‘Jet Trail’ (unpatented) and ‘Toyo-Nishiki’ (unpatented).
