Traits Analysis of the Gerbera jamesonii hybrids Cross-bred Seven New Cultivars for Cut Flower Cultivation
Abstract
This study was conducted to obtain the basic data to respond to the increasing cost for seeds and seedlings of Korean farms because of imposed royalty payment as Korea joined the UPOV in 2002 and the Seed Industry Act was implemented in 1997. The study was conducted for 10 years from 2000 to 2010 and bred seven cultivars of double flowered gerbera. Sowing was done promptly after obtaining seeds by cross pollination. A greenhouse owned by the Sangmyeong Seed Company was utilized for cultivation. During cultivation. they were observed and superior individuals were pedigree selected. The selected pedigrees were propagated by vegetative propagation using plant tissue culture techniques and the propagules were planted to investigate their stable expressions of characteristics. The selected cultivars were named and applied for official cultivar registration at the Korea Seed and Variety Service.
Through the processes as described above, cultivation goals could be set up before cross pollination. Therefore, this study results are expected to serve as the basic data for cultivation of the following cultivars.
1. 'White UFO'
The 'White UFO' is a white-colored (RHS 155B) semi-double flowered cultivar with black core. In 2004, a cross pollination of 'Himalaya' × 'Wonder King' was made and 89 seeds were obtained. The seeds were promptly sown and the resulting plants were cultivated and observed until 2007 when the selection was made. This cultivar has large-size flowers and is characterized to have 13 cm long peduncles and 60 cm long flower stalks. The outer ray flowers are regular and the color is white (RHS 155B). The longevity of cut flowers is 12.5 days. The number of days from seedling planting to the first florescence is 105 days. The number of collected flowers per year is 45. It was named in 2007, and a cultivar registration to the Korea Seed and Variety Service was applied and the cultivar was registered in 2009.
2. 'Asadal'
The 'Asadal' is a red-colored (RHS 40B) semi-double flowered cultivar with a black core. In 2004, a cross pollination of 'Sangria' × 'Beauty' was made and 217 seeds were obtained and the selection was made in 2007. The cultivar has large flowers with 12 cm long peduncles and 65 cm long flower stalks. It has a black core and its external ray flowers and internal ray flowers are regular. Overall, its outer ray flowers and inner ray flowers are slightly yellow-colored at the tips as a fringed flower. The longevity of cut flowers is 11.0 days. The number of days from seedling planting to the first florescence is 102 days. The number of cut flowers produced per year is 50. It was named in 2007, and a cultivar registration to the Korea Seed and Variety Service was applied and the cultivar was registered in 2009.
3. 'Au-79'
The 'Au-79' is a yellow-colored (RHS 15A) semi-double flowered cultivar without a black core. In 2003, a cross pollination of 'Onedin' × 'Soledo' was made and 135 seeds were obtained and the selection was made in 2007. The cultivar has large flowers with 12 cm long peduncles and 65 cm long flower stalks. Its outer ray flowers and inner ray flowers are regular. The longevity of cut flower is 12.0 days. The number of days from seedling planting to the first florescence is 107 days. The number of cut flowers produced per year is 47. It was named in 2006, and a cultivar registration to the Korea Seed and Variety Service was applied in 2007.
4. 'Jamboree'
The 'Jamboree' is a semi-double flowered cultivar with a pastel-toned pink color (RHS 68D) flowers, but without a black core. In 2001, a cross pollination of 'Estel' × 'First Love' were made and 170 seeds were obtained and the selection was made in 2007. The cultivar has large flowers with 12 cm long peduncles and 60 cm long flower stalks. Its outer ray flowers and inner ray flowers are regular. The longevity of cut flowers is 11.5 days. The number of days from seedling planting to the first florescence is 105. The number of cut flowers produced per year is 55. It was named in 2007, and a cultivar registration to the Korea Seed and Variety Service was applied and the cultivar was registered in 2009.
5. 'Geummaru'
The 'Geummaru' has semi-double, overall yellow colored (RHS 6A) flowers without any black core. A cross pollination of 'Soledo' × 'SM-04-87' was made in 2005 and 105 seeds were obtained. The selection was made in 2009. The cultivar has large flowers with 12 cm long peduncles and 60 cm long flower stalks. Its outer ray flowers and inner ray flowers are regular. The longevity of cut flower is 12.0 days. The number of days from seedling planting to the first florescence is 105 days. The number of cut flowers produced per year is 48. It was named in 2009 and a cultivar registration to the Korea Seed and Variety Service was applied in 2010.
6. 'Haenarae'
The 'Haenarae' is a semi-double flowered cultivar without a black core. It has a yellow color (RHS 169B) petals fading slightly toward tips. In 2005, a cross pollination of 'SM06-25' × 'Sunway' was made as a duplicate and 78 seeds were obtained. The selection was made in 2009.
