A rose cultivar “Haedoji” developed at the Jeollanamdo Agricultural Research and Extention Services (JARES) is a standard type with deep Red flower. From 2000, two cultivars ‘Vital’ and Cardinal were examined for horticultural characteristics and were included in cross-combination in 2003. Cultivar ‘Vital’, a vigorous standard type, first preference with red flower, was used as a mother plant and cultivar ‘Cardinal’, a red flower standard type with light color, was used as a pollen-donor plant. seventeen six breeding lines were selected in 2004 based on flower shape, flower color and abundance of petal numbers on the first selection. two breeding lines were selected in 2004 based on powderly mildew and vigor on the second selection. For three years, from 2005 till 2007, one breeding lines were selected and examined for their productivity, and then cultivar “Haedoji” was developed because of distinctive characters such as light red color flower, upright stem, long vase-life and Resistance to the Powderly Mildew. A standard type with intermediate sized flower, cultivar “Haedoji” shows in average 9.2 cm flower diameter, 62.0 cm flower stem length, and 9.5 days vase-life. The average productivity for three years was 167.3 stems ㆍm -2 per year and increased 2% compare to cultivar ‘Tiamo’ with 163.9 stemsㆍm -2 per year.
