A new bright yellow gerbera (Gerbera hybrida Hort.) cultivar, 'Joyful', was released by the Flower Research Institute of Gyeongsangnam-do Agricultural Research & Extension Service in 2013. 'Joyful' was developed in Changwon from 2005 to 2006 and is a cross between 'Chowoo', a semi-double type gerbera cultivar with yellow-orange colored flowers, and 'Focus', a semi-double type cultivar with yellow colored flowers. The characteristics trials for selection were conducted from 2007 to 2009. 'Joyful' has large, semi-double type flowers with yellow (RHS, 12-A) ray florets and a brown central part. It also has a stable flower shape, strong peduncles, and a vase life of 12.8 days. The average flower yield of 'Joyful' was determined in greenhouse trials carried out from 2008 to 2010 and is 49.2 stems per plant per year. 'Joyful' was demonstrated to be a new cultivar based on ploidy tests and RAPD analysis and was registered (Grant No. 4574) to the Korea Seed and Variety Service (KSVS) for commercialization in 2013.

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 gerbera (Gerbera hybrid Hort.) 'Azalin' was bred by the National Institute of Horticultural & Herbal Science in 2009. 'Basic' and 'Rosabella' which had pink color and semi-double flower were crossed in 2006. After investigation of the characteristics for four years (from 2006 to 2009), it was selected specially for the use of cut flower. The 'Azalin' had brilliant pink color (RHS RP68A) with green disc center. The flower was semi-double and 10.6 cm in diameter. It had a thick peduncle of which upper and lower width were 3.7 mm and 5.5 mm, respectively. The average days to first flowering of 'Azalin', 88.5 days, was approximately 8.7 days earlier than the control cultivar. And its average yield, 55.8 stems per plant, was also 7.4 stems per plants more than the control cultivar.

This study was conducted to obtain a basic information on the structural and histological characteristics of Gerbera hybrida Hort. leaf injured by american serpentine leafminer (ASL), Liriomyza trifolii, by using light and scanning electron microscope (SEM). Based on the anatomical observation of leaf blade injured by L. trifolii, the injury process could be divided into three stages. In the initial stage, the punctured tiny holes where ASL layed eggs after suction in the upperside of leaf were observed in the palisade parenchyma. In the middle stage, the hatched larvae made mines in the palisade parenchyma only. In the final stage, the mature larvae grew up making the mines bigger, and just before going out from the epidermis, it injured the inside of leaf containing one layer palisade parenchyma and two layers of spongy parenchyma.

A new bi-color mini gerbera (Gerbera hybrida Hort.) 'Sun Cap' was developed from a cross of '99-ga-2' and '99-na-3-1' followed by seedling and line selections at the Flower Research Institute, Gyeongnam Agricultural Research and Extension Services (ARES) in 2007. Characteristic tests were conducted three times from 2004 to 2007. 'Sun Cap' has single type in good harmony with bi-color (Red/Yellow, RHS 45-B/9-A) ray floret and green center. It has good stable flower shape and strong peduncle. Its vase life was 13.5 days. The average yield of 'Sun Cap' was 102.6 flowers per plant a year in greenhouse. Yield trials were carried out from 2004 to 2007. This cultivar was registered for commercialization in 2009. 'Sun Cap' would be cultured under greenhouse condition in Korea.

A new gerbera variety "Red Line" was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2008. A cross was made between "Mirage" with orange and double and "Rose" with red and semi-double in 2005. After investigation of the characteristics for four years (from 2005 to 2008), it was selected specially for the use of cut flower. "Red Line" is a vigorous cultivar with red (RHS R44B), black center and semi-double. The average flower diameter is 12.7 cm, large flower. And inner ray floret and disc diameter are 8.10 cm and 2.80 cm, respectively. It produces a large yield with continuous supply of flowers and has adequate peduncle height. We believe that "Red Line" has a great potential for expanding cultivated area of domestic gerbera cultivars and increasing farmers-income.

A new gerbera cultivar 'Lovely Moon' was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2008. A cross was made between 'Sever Line' and 'Angel' with yellow and semi-double flower in 2005. After investigation of the characteristics for four years (from 2005 to 2008), it was selected specially for the use of cut flowers. 'Lovely Moon' is a vigorous cultivar with yellow (RHS Y13B), yellow green center and semi-double flower. The average flower diameter is 12.7 cm, a large flower. And inner ray floret and disc diameter are 6.10 cm and 2.80 cm, respectively. It produces a large number of flowers with continuous supply of flowers and has a long peduncle height. We believe that 'Lovely Moon' has a great potential for expanding cultivated area of domestic gerbera cultivars and increasing farm income.

A new gerbera cultivar 'Sunny Lemon' was released by the National Institute of Horticultural and Herbal Science (NIHHS) in 2009. A cross was made between 'Pavlov' and 'Patrick' with pink and semi-double in 2006. After investigation of the characteristics for four years (from 2006 to 2009), it was selected for the use of cut flower. 'Sunny Lemon' is a vigorous cultivar with yellow flower color (RHS Y9C), brown center and semi-double. The average flower diameter is 11.0 cm. And inner ray floret and disc diameter are 7.63 cm and 2.59 cm, respectively. Days to first blooming are 84.5, approximately 2 weeks earlier than the standard cultivar. It produces a large yield with continuous supply of cut flowers and has adequate peduncle height. We believe that 'Sunny Lemon' has a great potential for expanding cultivated area of domestic gerbera cultivars and increasing farmers' income.

A new gerbera cultivar 'Whiteny' was released by the National Institute of Horticultural & Herbal Science in 2009. A cross was made between 'Wonder King' with white semi-double and 'Ever Green' with pale greenish white and semi-double in 2007. After evaluation of the characteristics for four years (from 2007 to 2010), it was selected specially for the use of cut flower. The 'Whiteny' cultivar has pure white color (RHS W155D) with black disc center and semi-double flower. The average flower diameter is 11.5 cm, large-sized flower. And inner ray floret and disc diameter are 7.8 cm and 2.2 cm, respectively. It has a long peduncle height, 52.2 cm, and longer vase life, 12.1 days. And it is also adaptable to the local cultural environment of Korea. It is expected that if the 'Whiteny' cultivar is planted, the royalty paid to foreign varieties can be saved. And the local growers will also be benefitted since the cost of cultivars will be lower than the imported ones.
