A New Pot Plant Variety Bred by Interspecific Crossing between Tecoma stans (L.) H.B.K. and T. garrocha Hieron.

Confirmation of hybridity using GISH and determination of 18S rDNA copy number using FISH in interspecific F1hybrids ofTecoma(Bignoniaceae)

“…We successfully used T. stans as a staminate parent in crosses with T. garrocha, which differs from previous attempts to cross these two species. Kobayashi et al (2004) reported viable seed set when T. stans was used as the pistillate parent but observed set fruit with no viable seed in reciprocal crosses.…”

“…Smith (1894) reported that it flowered as early as 6 months from seed and produced flowers year round in South Australia. More recently, controlled crosses have resulted in an interspecific hybrid of T. stans × T. garrocha (Kobayashi et al 2004). Fruit set was observed when T. garrocha was used as the pistillate parent, but fertile seed were only obtained when T. stans was used as the pistillate parent (Kobayashi et al 2004).…”

Fruit set was observed when T. garrocha was used as the pistillate parent, but fertile seed were only obtained when T. stans was used as the pistillate parent (Kobayashi et al 2004). Also, Gentry (1990) reported successful hybridization between bee-pollinated (yellow) species and hummingbird-pollinated (orange to red-orange) species.…”

“…Identification of hybrids traditionally has been performed through morphological comparison, including in Tecoma spp. hybrids (Kobayashi et al 2004). However, this may sometimes be difficult when the morphology of the parental species overlaps.…”

Development of a New Hibiscus Cultivar ‘Daewangchun’ with Vigorous Growth and Unique Red Eye through Interspecific Hybridization

“…However, the number of possible genetic barriers is very high (Eeckhaut et al, 2006). The creation of interspecific hybrids, along with chromosome doubling technology, offers extended opportunities for ornamental breeders (Van Tuyl and Kim, 2003), as demonstrated in many genera (Sujatha and Prabakaran, 2003, Kobayashi et al, 2004, Van Huylenbroeck et al, 2004.…”
