Nowadays most parts of vegetable breeding in Korea have been conducted by private seed companies. However, in the beginning stages of breeding research, Horticulture Experiment Station played a crucial role. Major vegetable varieties that are distributed from Korea are produced as F1 hybrids. Korea has developed leading techniques and human infrastructure for vegetable breeding. Such brilliant developments have resulted from three major factors: changes in the composition of varieties, the establishment of year-round vegetable production, and the development of the seed export market. First, an F1 hybrid system increased seed performance more than traditional open pollinated (OP) varieties with respect to productivity, uniformity and disease resistance. Moreover, an F1 hybrid system required repetitive seed production and provision, which increased the economic growth of seed companies. Second, vegetables tend to be consumed fresh instead of dried or processed. Finally, vegetable seed exports have continuously increased with the aid of R&D projects such as the Golden Seed Project (GSP). Therefore, for further progress of the vegetable industry, new varieties that can meet consumers’ demands, as well as the stable provision of fresh vegetables, are required. Contrary to the past, the future focus must be concerned with productivity and cultivation stability, the development of high value, functional, eco-friendly vegetables, and high quality vegetables. To cope with this, every breeding subject, including industry, universities, and institutes, have to collaborate with the aim of advancing vegetable breeding in Korea.

We developed high-quality Korean pepper (Capsicum annuum L.) varieties to compete with imported chili peppers from China. The ‘OH95’ line, which was introduced from Hungary in 1997, was self-pollinated, and the resulting ‘62067L2’ was selected as a pigment-rich maternal line in 2003. However, RSS and LV2319, both developed in 1993, were cross-bred, after which the paternal line ‘62027R3’ was developed by consecutive selections and generation advancement. After the cross combinations were performed, their horticultural characteristics were evaluated for two years, and subsequently, regional adaptation trials were conducted for at three different sites over three years. Of these, a new pepper variety, ‘Jeockyoung’ exhibited an average ASTA value of 175, representing pigment content, which was approximately 43% higher than that of a commercial cultivar ‘Manitta’. In addition, the capsaicinoid content of ‘Jeockyoung’ was 114.4±11.6 mg/100 g, which was slightly higher than that (86.3±2.8 mg/100 g) of the control cultivar. Moreover, regional adaptation trials revealed that the new variety showed regional differences in annual yield| however, the yield was approximately 18% higher than that of the commercial cultivar. Fruit weight, length, and diameter of the new variety were approximately 21.8 g, 14.3 cm, and 2.2 cm, respectively. The flowering period was approximately 101 days after sowing, which was similar to that of the control cultivar. In addition, leaf length and plant height were also not different from those of the control cultivar.
