“…Flowers of hybrids were smaller than those of the parental carnation but larger than those of the parental wild Dianthus. These morphological inheritances are the same as previous reports (Nimura et al, 2003;Nimura et al, 2006;Seo and Soichi, 1998). Round and double petals are preferred morphological traits of ornamental carnations as well as larger flower size.…”

Most modern carnation (Dianthus caryophyllus L.) cultivars have weak fragrances dominated by the scent of methyl benzoate. Wild Dianthus species with strong or unique scents may be useful gene resources for the improvement of carnation fragrances. We investigated the scents of interspecific hybrids between carnations and fragrant wild species by gas chromatography-mass spectrometry (GC-MS), and evaluated the usefulness of wild species for fragrant breeding in carnations. Dianthus hungaricus, which produced large amounts of various benzenoids, was crossed with a carnation with a floral scent dominated by methyl benzoate, but benzenoid diversity was not increased in the interspecific hybrid. We also analyzed some existing interspecific hybrids. Dianthus superbus var. longicalycinus had high amounts of β-ocimene and β-caryophyllene. These terpenoids were acquired as principal scent compounds by some interspecific hybrids between this species and a carnation lacking terpenoids. Three unidentified wild species (Dianthus sp. 4, 5, and 6) emitted high amounts of benzenoids, including eugenol, benzyl alcohol, methyl o-anisate, and methyl salicylate. These benzenoids were also detected in interspecific hybrids between carnations and the wild species, and the amounts were increased compared to the parental carnation. The emission of these scent compounds of wild Dianthus species was inherited by most hybrids lines; the variety and amounts of scent compounds tended to increase compared to parental carnations, although there was no general hereditary pattern. As we actually sensed the fragrances of the principal compounds from some hybrid flowers, the usefulness of interspecific hybridizations for the improvement of flower fragrances was confirmed. Dianthus superbus var. longicalycinus and Dianthus sp. 4, 5, and 6 seemed promising resources regarding the addition of terpenoids and the increase in benzenoid variation in the floral volatiles of carnations.

Thirteen SSR (simple sequence repeat) markers were successfully developed in carnation using an enriched genomic library method. All 13 primer pairs designed could successfully amplify target fragments of the expected size for the original variety 'Francesco' or 'Barbara'. Thirty-nine of 41 carnation varieties, except for mutant varieties, were successfully distinguishable using 32 putative alleles and 15 polymorphic bands produced from 13 SSR markers. 'U Conn Sim' and 'White Sim', which are bud mutants originated from 'William Sim', showed an identical genotype to 'William Sim'. Three (CB026a, CB057a, and CB060a) of 13 SSR markers were thought to be derived from multi-locus because the 3 SSR markers produced more than 3 discrete amplified fragments. The number of alleles per locus ranged from 1 (CB020a and CB041a) to 9 (CB003a), with an average value of 3.2. The values of the observed heterozygosity (H O ) and the expected heterozygosity (H E ) ranged from 0 to 0.59 (mean 0.30) and 0 to 0.68 (mean 0.34), respectively. The power of discrimination (PD) ranged from 0 (CB020a and CB041a) to 0.93 (CB026a) (mean 0.49). The parentage of 2 carnation varieties from intraspecific crosses was analyzed using 10 SSR markers, and the hybridity of the progenic varieties was confirmed. SSR markers were very effective for variety discrimination and determination of carnation parentage.

“…Another possible barrier regarding interspecific hybridization is related to the combination nucleuscytoplasm (Nimura et al 2003). Negative interactions may endanger the embryo or cause failure in the development of the endosperm.…”

-(Hybridization among wild passionflower species). Passion fruits are appreciated for their ornamental value, since their flowers are showy and display a wide variety of colors. In addition, many hybrids have been produced and used in other countries. The genotypes used in selection of plants with ornamental characteristics are hybrid progenies which are used in various crossing strategies. Thus, the aim of this work was to obtain interspecific hybrids, perform backcrossing and obtain progenies from crossings between hybrids, and to determine the reproductive compatibility between the progenitors involved. Key words -interspecific crossing, ornamental plants, Passiflora, seed germination RESUMO -(Hibridação entre espécies silvestres de passifloras). As passifloras são apreciadas por seu valor ornamental, pois suas flores são vistosas e com enorme diversidade de cores, e muitos híbridos têm sido produzidos e utilizados em outros países. As fontes para seleção de plantas com características ornamentais são progênies híbridas utilizadas em variadas estratégias de cruzamentos. Assim, os objetivos do trabalho foram obter híbridos interespecíficos, realizar retrocruzamentos e obter progênies de cruzamentos entre híbridos e, desta forma, verificar a compatibilidade reprodutiva entre os genitores envolvidos. Foram registrados o percentual de flores fertilizadas e de germinação, além do número de frutos, de sementes e de plantas obtidos por cruzamento. Realizaram-se 374 hibridações envolvendo sete espécies e dois híbridos. Cruzamentos como Passiflora gibertii N. E.
