Lychnis belongs to Caryophyllaceae and contains a number of horticulturally attractive species. In order to widen their variations in horticultural traits, interspecific cross-pollination and subsequent immature seed culture were carried out using 8 Lychnis species, L. chalcedonica, L. coronata, L. fulgens, L. gracillima, L. kiusiana, L. miqueliana, L. sieboldii, and L. wilfordii. Enlarged fruits containing immature seeds were obtained in the 26 cross-combinations 4 weeks after pollination. Immature seeds were isolated from the fruits and cultured on halfstrength Murashige and Skoog medium without plant growth regulators, on which germination occurred in 11 cross-combinations and seedlings were produced in 8 cross-combinations. However, green seedlings were obtained only in L. fulgens × L. sieboldii, and seedlings obtained from the other 7 cross-combinations,kiusiana, and L. wilfordii × L. sieboldii, were albino and died during acclimatization. The hybridity of all 55 green seedlings obtained from L. fulgens × L. sieboldii was confirmed by random amplified polymorphic DNA analysis. Although some morphological variations were observed among hybrids, hybrid plants generally showed intermediate morphologies between the parents. Hybrids showed high pollen fertility and their selfpollination yielded viable seeds. The present study shows the possibility of interspecific cross-breeding in Lychnis. Further studies are necessary to improve the culture conditions of immature seeds and to examine interspecific cross-compatibility using a wide range of Lychnis species.

“…Hybridization has been used to test the phylogeny relationship of Lychnis and Silene (Kruckeberg, 1962;Wilson et al, 1995). A number of cultivars are commercially available and were obtained from intraspecific breeding (Godo et al, 2009;Mayol and Rossello, 2006). An exceptional example is Lychnis •arkwrightii Heydt, which is a putative hybrid between Lychnis chalcedonica L. and Lychnis •haageana Lemoine.…”

Hybridization at intraspecific, interspecific, and intergeneric levels is a well-known breeding strategy to create variations with desirable traits for ornamental flowers. A total of 161 crossing combinations were made on three taxonomic levels, including 12 intraspecific crossing combinations within L. chalcedonica and L. ×haageana, 102 interspecific crossing combinations within Lychnis spp., and 47 intergeneric crossing combinations between Lychnis spp. and Silene spp. Intraspecific crosses showed high cross-compatibility, which yielded mature seeds and progeny plants. Most of the interspecific crossings in genus Lychnis produced limited seed set and germination percentages; however, L. cognate, L. ×arkwrightii, and L. ×haageana showed high cross-compatibility and might be more closely related than other species in Lychnis. As a result of cross-incompatibility, crossing combinations between Lychnis spp. and Silene spp. produced few flowers that set seeds. Significant differences occurred in seed set between crossing combinations and their reciprocal crosses for interspecific and intergeneric crosses. For these hybrids with immature seeds, embryo rescue techniques with immature seed culture would be the only way to produce seedlings.
