Title: Petunia plant named ‘SAKPET001’

Description:
Genus and species:  Petunia hybrida.    
     Variety denomination: ‘SAKPET001’. 
     BACKGROUND OF THE NEW PLANT 
     The present invention comprises a new and distinct cultivar of  Petunia , botanically known as  Petunia hybrida , and hereinafter referred to by the cultivar name ‘SAKPET001’. It is characterized by having a magenta flower with eye and a semi-creeping plant habit. The new cultivar originated from a hybridization made in Kakegawa, Japan in 2005. The male parent was a proprietary  Petunia  breeding line named ‘03BCR-14A’ (unpatented) and had magenta with white corolla throat flower color and a creeping plant growth habit. The female parent was a proprietary  Petunia  breeding line named ‘9S-351-3A’ (unpatented) and had a red morn flower color and a semi-dwarf plant growth habit. 
     In June 2005, an F1 generation from the initial hybridization was grown and approximately 500 seeds were obtained. In August 2005, 50 seeds out of the 500 total seeds were sown and 16 plants were cultivated in a greenhouse. Segregation in the F1 generation resulted in plants that had salmon, rose, or magenta flower color and either creeping or semi-creeping plant growth habit. In October 2005, a plant that exhibited magenta with eye-colored flowers and a semi-creeping plant growth habit was selected. 
     In February 2006, the selection was asexually propagated through plant cuttings in Kakegawa, Japan. Plants of the selection were cultivated and in May 2006, the selected line was observed to have its distinct characteristics remain stable. In July 2006, the selection was asexually propagated again and cultivated. In October 2006, it was confirmed that the line has been shown to reproduce true-to-type in successive generations of asexual propagation. The selection was subsequently named ‘SAKPET001’.

     DESCRIPTION OF THE NEW CULTIVAR 
     The following detailed description sets forth the distinctive characteristics of ‘SAKPET001’. The data which define these characteristics were collected from asexual reproductions carried out in Salinas, Calif. The detailed description was taken from plants grown under greenhouse conditions for approximately four months from transplanting of rooted cuttings into 6-inch pots. Plants were pinched once during growth. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 4 th  Edition.

         Environmental conditions for plant growth: The terminal 1.0 to 1.5 inches of an actively growing stem was excised. The vegetative cuttings were propagated in five to six weeks. The base of the cuttings were dipped for one to two seconds in a 1:9 solution of DIP &#39;N GROW (1 solution: 9 water) root inducing solution immediately prior to sticking into the cell trays. Cuttings were stuck into plastic cell trays having 98 cells, and containing a moistened peat moss-based growing medium. The cuttings were misted with water from overhead for 10 seconds every 30 minutes until sufficient roots were formed. Rooted cuttings were transplanted and grown in 20.0 cm diameter plastic pots in a glass greenhouse located in Salinas, Calif. Pots contained a peat moss-based growing medium. Soluble fertilizer containing 20% nitrogen, 10% phosphorus, and 20% potassium was applied once a day or every other day by overhead irrigation. Pots were top-dressed with a dry, slow release fertilizer containing 20% nitrogen, 10% phosphorus, and 18% potassium. The typical average air temperature was 24° C.

     COMPARISON WITH KNOWN CULTIVARS 
     ‘SAKPET001’ is a new and distinct cultivar of  Petunia  having magenta flowers with eye and a semi-creeping plant growth habit. ‘SAKPET001’ is most similar to the commercial  Petunia  variety ‘Kakegawa S36’ (U.S. Plant Pat. No. 14,037). Table 1 compares some traits of ‘SAKPET001’ to those of ‘Kakegawa S36’:
