Title: Carnation plant named ‘CFPC Mahalo’

Description:
Botanical classification:  Dianthus caryophyllus.    
     Variety denomination: The new carnation variety denomination is ‘CFPC Mahalo’. 
     BACKGROUND OF THE INVENTION 
     The present invention comprises a new and distinct cultivar of hybrid carnation botanically known as  Dianthus caryophyllus,  and referred to by the cultivar name ‘CFPC Mahalo’. The new variety, identified as selection no. 090152, originated from a cross made by Oscar Hasegawa in a controlled breeding program in Salinas, Calif. 
     The female parent of the new variety is known as selection no. 080106 and the male parent is known as selection no. 080196. The new variety ‘CFPC Mahalo’ has been asexually reproduced by vegetative side shoot cuttings in Salinas, Calif. and the distinguishing characteristics are retained through successive generations of asexual reproduction. 
     BRIEF SUMMARY OF THE INVENTION 
     ‘CFPC Mahalo’ is a potted spray-type carnation plant variety having a compact form of plant with well presented pink flowers. 
     Comparison with Female Parent 
     Plants of the new carnation variety ‘CFPC Mahalo’ are similar to the female parent selection no. 080106 in plant habit and growth rate. Under similar growing conditions in Salinas, Calif., under commercial practice, plants of the new carnation variety ‘CFPC Mahalo’ differed from plants of the female parent in the following characteristic:
         1. The new variety ‘CFPC Mahalo’ produces pink flowers whereas the female parent selection no. 080106 produces lighter pink color flowers.       

     Comparison with Male Parent 
     Plants of the new carnation variety ‘CFPC Mahalo’ are similar to the male parent selection no. 080196 in plant habit and growth rate. Under similar growing conditions in Salinas, Calif., under commercial practice, plants of the new carnation variety ‘CFPC Mahalo’ differed from plants of the male parent selection no. 080196 in the following characteristic:
         1. The new variety ‘CFPC Mahalo’ produces pink flowers whereas the male parent selection no. 080196 produces darker pink flowers.       

     Comparison with Other Similar Varieties 
     Plants of the new carnation variety ‘CFPC Mahalo’ are similar to plants of the variety ‘CFPC Annette’ (U.S. Plant Pat. No. 17,596) in plant habitat and growth rate. Under similar growing conditions, however, in Salinas, Calif., under commercial practice, plants of the new carnation variety ‘CFPC Mahalo’ differed from plants of ‘CFPC Annette’ in the following characteristics:
         1. The flower color of the new variety ‘CFPC Mahalo’ is a darker pink than the flower color of ‘CFPC Annette’.

     DETAILED BOTANICAL DESCRIPTION 
     The following description of the new carnation variety ‘CFPC Mahalo’ is of plants 139 days from a planting date Dec. 6, 2009, grown in a commercial greenhouse in Salinas, Calif. The cultivar has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in the environment such as temperature, length of day and light intensity without any variance in genotype. 
     Plants of the new variety have been grown successfully under temperature conditions averaging about 18° C. at night and about 24° C. to 28° C. during the day under light conditions of about 14 hours. Plants are daylight neutral and flower throughout the year. Chemical growth regulators are not required for production. The new variety may be produced as a potted spray-type carnation. To produce a commercial product the plants may be pinched once with the center bud removed. Pinched plants are about 6 inches tall and about 8 inches in diameter. Flower diameter averages about 2¼ inches with a crown of about 1 inch. Foliage is generally about 3 inches long and about ¼ inch at the widest point. The typical container size for commercial growth is 4½ inches. 
     It has been observed that the shelf life of the new variety is about 21 days with a time to first bud opening of about 15-16 weeks. The commercial classification of the new carnation variety is a potted spray-type. The plant hardiness zone has not been determined. 
     The following description is with respect to a plant produced as a potted spray-type carnation. The plant and flower measurements and foliage size are established as an average using standard commercial cultural practices. In the description of this new carnation variety, color values have been taken from The Royal Horticultural Society Colour Chart (R.H.S.C.C.).
