 note = {In order to breed new allium varieties with blue flowers and sweet fragrance, we conducted interspecific hybridization between Allium caesium Schrenk and Allium caeruleum Pallas. We crossed 250 flowers of A. caesium with A. caeruleum in 1999. Ovaries were collected 20 days after pollination. A total of 590 ovules were excised, placed onto a 1/2 MS medium containing 3% saccharose, and cultured at 25℃ under a 16-hour light cycle. After 3 months of culture, 83 ovules had germinated. Plantlets that developed normally through the ovule culture were transplanted to pots containing vermiculite. In 2001, 53 of these seedlings flowered, and 5 plants were selected on the basis of flower color and fragrance. In 2004, we finally chose 2 of the 5 previously selected seedlings, and we named them 'Allium Sapporo No.1' and 'Allium Sapporo No.2' and applied for registration in 2005. The flowers of 'Allium Sapporo No.1' have a dark grayish blue midvine on a pale violet ground, and those of 'Allium Sapporo No.2' have a dull green midvine on a bluish white ground. The flowers of both varieties have a sweet fragrance like vanilla essence. Bulbils are absent in the inflorescence. Both varieties have a long and thick flower stem. The earliest flowering with good-quality flowers is obtained when the bulbs are chilled at 5℃ for 3 months for 'Allium Sapporo No.1' and for 2 months for 'Allium Sapporo No.2'.},
