“…Interspecific hybridization is an effective way to transfer target traits to ornamental crop plants (Mii, 2009). One or several desirable traits, including flower type, color, flowering time and resistance to biotic and abiotic stresses, have been introduced to ornamental plants in the Allium, Chrysanthemum, and Dianthus genera (Cheng et al, 2011;Gatt et al, 1998;Nomura et al, 2002). Regarding the genus Paeonia, Itoh hybrids are the result of a successful interspecific hybridization of Paeonia species and present an improved flowering period and disease resistance (Page, 2005).…”

Insufficient light intensity inhibits the growth of cultivated herbaceous peony and decreases its economic value. Owing to the increased demand for shade-tolerant herbaceous peony, the selection of appropriate parents for hybridization is essential. Paeonia anomala, Paeonia intermedia and Paeonia veitchii can grow under shade conditions in their natural habitats; however, their photosynthetic capacities under shade have not been studied. In this study, we simulated low light intensity (30% sunlight) and evaluated the morphological, photosynthetic and chlorophyll fluorescence parameters of these three species. Moreover, the shade tolerance of these species as well as two common cultivars (Paeonia lactiflora ‘Da Fugui’, which is suitable for solar greenhouse cultivation, and P. lactiflora ‘Qiao Ling’, which is not suitable for solar greenhouse cultivation) was evaluated. The results showed that under shade, the leaf area of P. anomala and P. intermedia increased, the single flowering period of P. intermedia and P. veitchii was prolonged, and the flower color of P. veitchii faded. With respect to P. anomala, P. intermedia and P. veitchii, shade eliminated the photosynthetic ‘lunch break’ phenomenon and decreased photoinhibition at midday. Furthermore, the maximum photochemical efficiency (Fv/Fm) and maximum primary photochemical yield (Fv/Fo) of photosystem II (PSII) in the three species improved significantly, and their changes in light dissipation were different. The shade tolerance of the tested accessions was in the order P. veitchii > P. intermedia > P. anomala > ‘Da Fugui’ > ‘Qiao Ling’, showing that the three wild species were better adapted to low light intensity than the cultivars. Thus, P. anomala, P. intermedia and P. veitchii could potentially be used in the development of shade-tolerant herbaceous peony cultivars.

“…In a project to create ornamental Allium hybrids from fall-blooming and summer-blooming species, hybrids of Allium chinense x A. schubertii and of A. thunbergii x A. caeruleum bloomed at a time intermediate to both parents (Nomura et al, 2002). Moreover, the ornamental Allium hybrids created from these crosses bloomed by 2 years after pollination, more quickly than other ornamental Alliums (Nomura et al, 2002). Furthermore, rooting data .) had a rooting ability that was less than that of the easilyrooted mugwort parent but greater than that of the chrysanthemum parent (Deng et al, 2012).…”

“…Earlier blooming might indicate hybridity of these plants, as changes in flowering time are sometimes seen in hybrid plants. In a project to create ornamental Allium hybrids from fall-blooming and summer-blooming species, hybrids of Allium chinense x A. schubertii and of A. thunbergii x A. caeruleum bloomed at a time intermediate to both parents (Nomura et al, 2002).

Interspecific and intergeneric crosses were performed between species in the genera Baptisia and Thermopsis with the goal of creating hybrids with the best qualities of both parents. Baptisia australis (L.) R. Br. was used as both the male and female parent in intergeneric crosses. Thermopsis chinensis Benth. ex S. Moore, T. lupinoides (L.) Link, and T. villosa Fernald & B.G. Schub. were used as male and female parents in both interspecific and intergeneric crosses. Pollen was collected from B. alba (L.) Vent., B. bracteata Muhl. ex Elliott, and B. lanceolata (Walt.) Ell. and used to make interspecific and intergeneric crosses. Putative hybrids were obtained from both interspecific and intergeneric crosses. Interspecific crosses produced a higher percentage of pollinations resulting in seed set and the number of seeds per pollination than intergeneric crosses. Morphological differences between parent species and progeny were evident in putative hybrids resulting from intergeneric crosses between T. villosa and B. australis and T. villosa and B. alba. Most putative hybrids bloomed during the second year after germination. Because seedlings could be obtained from both interspecific and intergeneric crosses, hybrids within and between the genera Baptisia and Thermopsis are feasible. The Fabaceae family contains 670–750 genera and 18,000–19,000 species. Baptisia (commonly called false or wild indigo) and Thermopsis (commonly named false lupine) of the Fabaceae belong to the tribe Thermopsidae, which comprises 46 species in six genera. All species in Thermopsis and Baptisia are herbaceous; they are the only two genera in Thermopsidae that do not have woody species. Thermopsis contains 23 species and has a wide-spread distribution with species endemic to Asia and much of temperate North America. Although Thermopsis is considered to have originated in central Asia, T. chinensis Benth. ex S. Moore and T. fabacea (Pallas) Candole are thought to have originated in North America and migrated over the Bering Land Strait to Asia. Three Thermopsis species, T. fraxinifolia Nutt. ex M.A. Curtis, T. mollis (Michx.) M.A. Curtis ex A. Gray, and T. villosa Fernald & B.G. Schub., are native to the southeastern United States. Baptisia contains 15–17 species that are endemic to the southeastern and midwestern United States.

“…Advantageous expression of useful characters has been observed in other interspecific hybridizations conducted in various genera such as Cosmos ( Oku et al 2008 ), Primula ( Amano et al 2006 ), Allium ( Nomura et al 2002 ) and Kalanchoe ( Izumikawa et al 2008 ). In the present study, we have successfully created inter-sectional hybrids by reciprocal crosses between B. semperflorens and B.…”

Inter-sectional hybrids were successfully obtained by the reciprocal crosses between 11 cultivars (including 6 diploids and 5 tetraploids) of Begonia semperflorens (SS & SSSS genomes) and B. ‘Orange Rubra’ (RR genome) with the aid of in vitro culture of mature or immature seeds on MS medium containing 0.1 mg l−1 α-naphthylacetic acid, 0.1 mg l−1 6-benzyladenine, 10 mg l−1 gibberellic acid, 30 g l−1 sucrose and 2.5 g l−1 gellan gum. Embryo rescue as ovary culture with immature seeds 12th–16th day after pollination (DAP) generally gave higher efficiency of plantlet formation, but in some cross combinations, culture of mature seeds (30 DAP) resulted in higher yield of plantlets. Flow cytometric analysis revealed that they were consisted of the plants with various genomic combinations (RS, RR, RSS, RRS, RRSS and RRRRSS) as estimated by the DNA contents of both parents. Hybridity of these plants with various genomic combinations including RR was confirmed by random amplified polymorphic DNA analysis. These results suggested that unreduced gamete formation and spontaneous chromosome doubling were involved in the hybrid formation of various ploidy levels and genomic combinations. These hybrids showed various levels of intermediate traits between both parents according to the genomic compositions, and some of them had desirable characters of both parents.
