In Korea, gladiolus is mostly used as cut flower. In many cases corms from foreign cultivars are imported. The initial development of our gladiolus research started with testing new cultivars from abroad on cut flower quality, environmental adaptability, etc. In 1986, a gladiolus breeding program was initiated. The first new cultivars were released in 1995 with the reddish ‘Hongkwang’, and the bright orange-based ‘Hongeun’. During the period of 1998-2003, mainly red and white cultivars have been developed. Later on other colors and both very early flowering or very late flowering cultivars were introduced into the market. In 2012, the yellow colored cultivars with a lot of florets ‘Yellow Rock’ and ‘Focus’ have been developed. During this period breeding and selection of garden types started. A total of 49 cultivars have been developed to date. Every year, on average two or three new cultivars which are adapted to the local environmental growing conditions are released. Since 2002 research on resistance to thrips, which damages gladiolus leaves and flowers, is carried out. By crossing resistant genotypes, two new cultivars with improved thrips resistance could been developed. Finally in 2013 ‘Pink Smile’ was selected which has a good resistance towards the flower stalk bending phenomena in the wet summer conditions. In future, hybrids between spring flowering cultivars and autumn flowering cultivars with many and small florets will be developed.
