A new pink gerbera (Gerbera hybrida Hort.) cultivar 'Party Time' was developed from a cross between 'Hope' and 'Sunnyeo', followed by seedling and line selections at the Flower Research Institute of Gyeongnam Agricultural Research and Extension Services (GARES) in 2007. Detailed characteristics of the new cultivar were evaluated from 2005 to 2007. 'Party Time' has semi-double type large flowers in a good harmony with pink (RHS, 65-C) ray floret and brown center. It has a good, stable flower shape and strong peduncles, and its vase life was 12.7 days. The average flower yield of 'Party Time' was about 47.3 stems per plant a year in greenhouse yield trails carried out 2005 to 2007. 'Party Time' (Grant No. 2691) was registered to the Korea Seed and Variety Service (KSVS) for commercialization in 2009.

A new yellow gerbera (Gerbera hybrida Hort.) cultivar "Golden Time" was developed from a cross between '99-ga-2' and '99-na-7-6', followed by seedling and line selections at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) in 2007. Detailed characteristics of the new cultivar were evaluated from 2004 to 2007. "Golden Time" has semi-double type large flowers in a good harmony with yellow (RHS, 17-B) ray floret and brown center. It has good, stable flower shape and strong peduncles, and its vase life was 12.3 days. The average flower yield of "Golden Time" was about 49.5 stems per plant/year in greenhouse trails during 2004 and 2007. This cultivar was registered to the Korea Seed and Variety Service (KSVS) for commercialization in 2009. Year-round production of this cultivar is possible in the greenhouse condition throughout the Korean climate.

A new orange-colored, cut flower gerbera (Gerbera hybrida Hort.) cultivar 'Sweety' was developed from a cross between 'Grandeur' and 'Songsongee', followed by selections of seedlings and lines at the Flower Breeding Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 1999 to 2004. Three time evaluations were conducted from 2003 for the detailed characteristics of the new cultivar. 'Sweety' has semi-double type mini- or medium-sized flowers in good harmony with orange(RHS, 38-A) ray florets and a green center. It has good, stable flower shape and strong peduncle, and its vase life was 10.4 days. The average flower yield was about 51.0 stems per plant/year in greenhouse trails during 2003 and 2004. This cultivar was registered to the Korea Seed and Variety Service for commercialization in 2006. Year-round production of this cultivar is possible in the greenhouse condition in Korean climate.

A new orange mini gerbera (Gerbera hybrida Hort.) 'Yetty' was developed from a cross 'Haiti' and 'Nova Zembra' followed by seedling and line selections at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) from 2001 to 2006. Three times evaluations were conducted from 2004 for the detailed characteristics of the new cultivar, 'Yetty' has single type mini flower in good harmony with orange (RHS 25-A) ray floret and browen center. It has good stable flower shape and strong peduncle, and its vase life was 14.8 days. The average yield of 'Yerty' was 98.5 flowers per plant a year in greenhouse yield trials carried out from 2004 to 2006. This cultivar registered for commercialization in 2007. 'Yerty' would be cultured under greenhouse condition in Korea.

Chrysanthemum is one of the most popular ornamental plants worldwide. Recently, lots of new and novel chrysanthemum varieties have been developed using mutagenesis. However, there was no study for comparison of tissue culture condition among the mutant varieties derived from one original variety, until now. This study was conducted to compare the efficient regeneration condition of the two chrysanthemum mutant varieties, 'ARTI-purple' and 'ARTI-queen'. Two different flower parts (disk and ray florets) at the unopened and early blooming stages were used for comparison of regeneration condition on MS medium supplemented with combinations of three growth regulators (BA, NAA, and IAA). The highest regeneration rate was identified on the NAA and BA combination when the disk florets at unopened blooming stage are used. The best optimum combinations of growth regulators were identified as NAA $1.0mg{\cdot}L^{-1}$ and BA $0.5mg{\cdot}L^{-1}$ at 'ARTI-purple', which displayed 47.9% regeneration. However, regeneration of 'ARTI-queen' was the highest as 25.6% at NAA $2.0mg{\cdot}L^{-1}$ and BA $1.0mg{\cdot}L^{-1}$. There results indicate that there is a difference for the optimum regeneration condition between the mutant varieties derived from one original variety. These results will be useful for construction of efficient regeneration system of diverse chrysanthemum mutants developed by mutation breeding.
