1. This study was conducted to breed new cut rose cultivar for the domestic and export market. Breeding goals were with resistance to crown gall and powdery mildew. To make cross combination, over 50 parent varieties have resistance to Crown gall and powery mildew were collecting from 1992 to 2015.

1. This study was conducted to breed new cut rose cultivar for the domestic and export market. Breeding goals were with resistance to crown gall and powdery mildew. To make cross combination, over 50 parent varieties have resistance to Crown gall and powery mildew were collecting from 1992 to 2015. The lines of rose were selected from 2006 to 2010 and their characteristics of growth, flower color, stalk weight, stalk length and resistance to Crown gall and powery mildew were investigated in the vinyl house and glass house. 15 rose cultivar were released by NIHHS from 2011 to 2015.
2. This study was conducted to breed new cut rose cultivar for the domestic and export market. Breeding goals were with long vase life. To make cross combination, over 250 parent varieties have high quality and long vase life were collecting from 1992 to 2015.The lines of rose were selected from 2011 to 2015 and their characteristics of growth, flower color, stalk weight, stalk length and vase life were investigated in the vinyl house and glass house. 14 rose cultivar were released by NIHHS from 2011 to 2015. These cultivars can be propagated by both cutting and grafting.
3. Mutant breeding is need to get the difficult characteristics to be introduced by cross breeding, or to make different color or shape family varieties. For mutant breeding, pink spray cultivar ‘Glory Heart’, developed at National Institute of Horticultural and Herbal Science (NHHS) in 2009, was generated by radiation cobalt ray at Korea Atomic Energy Research Institute in spring 2010. After cobalt-irradiation during 24 hour, bud mutation was selected from the pot roses in winter 2010. The mutation, ‘10RM-10’, was propagated vegetatively and grown for three years under natural conditions in a glass greenhouse in NHHS. ‘10RM-10’ was mixed ivory and apricot color. and showed vigorous growth.
4. Breeding goals were with good growth and high quality of cut flower under the low temperature. To make cross combination, we used over 100 parent varieties have low-temperature resistance and collected from 1997 to 2015. The lines of rose were selected from 2006 to 2010 and their characteristics of growth, flower color, stalk weight, stalk length and powery mildew under the low temperature in winter season were investigated in the vinyl house and glass house. 10 rose cultivar were released by GARES(Gyeonnggi-do Agriculture Research and Extension Services) from 2011 to 2015.These cultivars can be propagated by both cutting. The consumer's preference of these cultivars are relatively higher than that of control cultivar.
5. Development of rose(Rose hybrida Hort.) cultivars were developed by seeding and line selection at the Flower Research Institute, Gyeongnam ARES from 2006 to 2012.

This new cultivar can be planted in almost greenhouse production region of Korea and will be released to general farmers in 2011～2015.
6. This study was conducted to breed new aromatic cut rose variety for the domestic and export market. Breeding goals were had nice perfume as well as nice characteristics for production of cut rose flower. We had crossed 13,745 flowers in made 663 cross combination from 2011 to 2015, used over 80 parent varieties have both perfume and well characteristics were collecting from 2007 to 2014. Gained seeds were sowed lock-wool media for sowing after treatment of low temperature. And young plant of germination were transpotted in 3 inch vinyl pot for selected 1^st time. Selected new rose lines were investigated in JARES green house for rose cultivation. As a result we made 165 lines of rose, evaluated their characteristics of growth, flower and level of perfume from 2011 to 2015. Finally 7 rose varieties were released by JARES from 2011 to 2014. These cultivars can be propagated by both cutting and grafting.
7. Breeding of new rose cultivar with viable under low light intensity This study was conducted to develop new rose cultivar which has viable under low light intensity and can be used for multipurpose. A series of works, such as cross, pedigree selection, and characteristics and performance test were performed from 2011 to 2015. Also, 30 lines and 230 lines were selected in the second and the first trials, respectively. 34,323 flowers of 1,208 cross combinations. Seed setting percentage was 21.8%. The first and second, and the third characteristics and performance test were took an experiment on 120 lines and 30 lines, respectively. Through appraisal of breeding line and official breeding council of agricultural crop, ten new roses included 'Lovely Heart', 'Pink shy' were selected and applied for a patent at Korea seed & variety service. Those new rose cultivars would contribute to save royalty as supplying to farmers after registering variety protection.
8. Breeding goals were with good growth and big flower diameter of cut flower for european export. To make cross combination, we used about 70 parent varieties have big flower diameter and high height from 2010 to 2015. The lines of rose were selected from their characteristics of growth and flower. 6 rose cultivar were released by Kynoss from 2011 to 2015. The consumer's preference of these cultivars are relatively higher than that of control cultivar.
9. Breeding goals were with small and medium flower diameter of cut flower for Japanese export. To make cross combination, we used over 100 parent varieties from 2010 to 2015. The lines of rose were selected from their flower and growth characteristics. 7 rose cultivar were released by Dowon rose garden from 2011 to 2015.
