 note = {In order to produce new varieties of rugosa rose (Rosa rugosa Thunb.) with a labor-saving tree form, we conducted intraspecific hybridization of 19 combinations among 7 lines in 1997, and 13 of these combinations bore a total of 89 hips. In 1998, 2145 seedlings grown from 4836 achenes were planted in an open field. In 1999, 612 of these seedlings flowered ; their floral characteristics were investigated for subsequent selection. In 2002, we finally chose 2 out of 88 previously selected seedlings with an oblate spheroidal tree form and a recurrent flowering habit, and named these 'Kakiken Teisei No.1' and 'Kakiken Teisei No.2', and applied for registration in 2003. 'Kakiken Teisei No.1' blooms with vivid reddish-purple blossoms (JHS Color Chart No.9207) with 5 petals about 8 cm across, and blossoms continuously for the remainder of the growing season. The blossoms of 'Kakiken Teisei No.2' are bright reddish-purple (JHS Color Chart No. 8905), about 6 cm in diameter, and are double-flowered, with an average of 23 petals in total. The 5-year-old seedling of 'Kakiken Teisei No.1' was 0.4×1.5m (height×width) in size, versus 0.3×1.7m for 'Kakiken Teisei No.2' . Both the cultivars can be propagated by means of cuttings, and 'Kakiken Teisei No.1' can flower in the year of propagation.},
