초록
This study was carried out to develop new zoysiagrass (Zoysia japonica Steud.) cultivar ‘Halla Green 2’ (Grantnumber: No. 118). To develop a zoysiagrass cultivar with dwarfism by using the mutation breeding method, the wild type control"Gosan" plants were irradiated using a 30 Gy gamma ray source in 2010. Dwarf mutants were selected from the mutated grassesin successive generations. Dwarf mutant lines were identified and a new zoysiagrass variety Halla Green 2 was developed. Theplant height of Halla Green 2 was 3.4 and 1.8 times lower than that of Gosan and Zenith, respectively. This cultivar has dwarfcharacteristics such as shorter sheath, shorter leaf blade, shorter flag leaf, and shorter third internode of stolon compared to thoseof Gosan and Zenith. Additionally, the sheaths and leaf blades color of Gosan, Zenith and Halla Green 2 were all light green,whereas their stolons were purple, yellow-green and yellow green, respectively. Trichomes(hairs) were visible on both adaxialand abaxial surfaces of the Gosan leaves, whereas only on the adaxial side of the Zenith and Halla Green 2 leaves. The HallaGreen 2 grass showed distinguishable morphological traits compared to those of wild type Gosan and Zenith.
