 note = {Improvement of the vase life of cut flowers is an important breeding target. Therefore, we initiated a research breeding program in 1992 to improve the vase life of carnations. We used conventional cross-breeding techniques to develop many  lines with long vase life. Repeated selection and crossing based on vase life was effective. Three cycles of selection and crossing to improve vase life led to a 3.1-day increase in the population mean from parental to third generation. We developed two new carnation cultivars that will continue blooming for 17.7 to 20.7 days (3.2 to 3.6 times the vase life of a standard cultivar, 'White Sim') under standard conditions (23℃, 12-h photoperiod, 70% RH). We registered these cultivars with Japan's Ministry of Agriculture, Forestries and Fisheries and released them in 2005 as Carnation Norin No.1 'Miracle Rouge' and No.2 'Miracle Symphony'. Treatment with α-aminoisobutyric acid, an inhibitor of ethylene biosynthesis, or silver thiosulfate, an inhibitor of ethylene action, did not significantly prolong vase life in either cultivar. In addition, the petals and gynoecium of both cultivars produced only trace amounts of ethylene during natural senescence. These results indicate that their ethylene biosynthesis pathway was almost completely blocked during natural senescence, and that this change was responsible for improved vase life.},
