Carnation and gerbera are economically important cut flowers in Korea. Their cultivated area and production value are 142ha and 29.6 billion won in 2013, respectively. In spite of their economic importance, most of cultivars have been imported from European countries including the Netherlands and Spain. For substituting imported ones, breeding and distributing domestic carnation and gerbera cultivars should be needed. This study was carried out to enhance the market share of domestic carnation and gerbera cultivars. Field tests of twenty two carnation and thirteen gerbera cultivars had been done in major cultivated area in 2013 to 2014. Through these, carnation including ‘Garnet’, ‘Geumbyel’, ‘Lila’, etc. and gerbera including ‘Harmony’, ‘Purple Queen’, ‘May Queen’, etc. were evaluated as elite cultivars by growers. During this period, market share of domestic gerbera cultivars were increased to 18.0%.
In addition, for investigating the morphological characteristics of peduncle break phenomenon occurred during cultivation in cut gerbera, we also observed the relation between stem break phenomenon and temperature of greenhouse. Domestic bred gerbera cultivar ‘Pruple Queen’ showed higher peduncle break at 56.5% growing time of peduncle.
And occurring position of peduncle break was at 61.3% upper part of peduncle. Stem of ‘Purple Queen’ is very strong and did not have cavity inside of peduncle, while ‘Harmony’ showed lower peduncle break had cavity in peduncle. So we can expect there is relation between peduncle break and cavity in peduncle.
Finally, we investigated the resistance of carnation against Fusarium spp. Wilted carnation plants were collected from National Institute of Horticultural and Herbal Science (NIHHS) and the carnation greenhouses in Gimhae, Gyeongsangnam-do. A total of 27 Fusarium spp. were isolated from discolored vascular tissues and roots. Twenty isolates out of 27 were identified as F. oxysporum based on the mycological characteristics and the translation elongation factor 1-alpha gene analysis. Among them, ten isolates of F. oxysporum were inoculated on 17 dometic carnation cultivars and 11 foreign cultivars in January, 2014. And pathogenicity test of twenty isolates on 28 foreign carnation cultivars, from May to August in 2014, showed that the majority of foreign cultivars were susceptible to FOD2, FOD22, FOD23 and FOD24. Wilt occurred starting at 10 days after the inoculation, but diminished according to the decrease in air temperature. Some cultivars showed different reactions from those marked in the previous pathogenicity test; therefore, screening of resistance of those cultivars is needed under temperature favorable to disease occurrence. From the results that Fusarium wilt does not develop under 18°C of average air temperature, we propose that fungicide against Fusarium wilt should be applied when average air temperature sustains above 18°C for more than one week.
