| Abstract: | This study was performed in order to check the applicability of a protocol for somatic embryogenesis in Cyclamen persicum and to compare the in vitro response of cultivars belonging to different cyclamen growth types and flower colours obtained from two breeders. One hundred
ovules per plant were prepared from 32 tested F1 hybrid cultivars represented by five plants each. Callus induction monitored after 8 weeks varied between 42 and 85%. Variation
occurred between replications and single plants of a cultivar. Consistency and colour of the developing calluses were diverse.
Only in 1 cultivar out of the 32 tested no regeneration of somatic embryos was obtained. The regeneration rates varied from
0 to 65% among cultivars. In the group of midi-type cultivars the regeneration response was lower than that in mini and giganteum
types. High regeneration rates were observed in cultivars with flamed flowers. |
