Abstract

Abstract The hybrid between Cattleya forbesii x Cattleya bowringiana shows flowers of lilac coloration, labellum with a light yellow center and striated with purple stripes of the same tone of other floral whorls. The plant flourished four years after seeding and produced, on average, six flowers.

Highlights

  • The cultivation of species of the Orchidaceae family and its hybrids has increased in the last decades, representing around 8% of the ornamental plants global market (Chugh et al 2009)

  • Considering the great genetic diversity of native species in Brazil, one strategy to leverage the national sector and make it self-sufficient is to establish Brazilian plant breeding programs for flowers and ornamental plants (Cardoso 2013); which makes it possible to obtain hybrids that are more adapted to our climatic conditions (Faria and Colombo 2015) and reduces the dependence on importation of Asiatic hybrids

  • The objective of this work was to describe the orchid hybrid originated for a cross between Cattleya forbesii x Cattleya bowringiana

Summary

Introduction

The cultivation of species of the Orchidaceae family and its hybrids has increased in the last decades, representing around 8% of the ornamental plants global market (Chugh et al 2009). In the Brazilian floriculture (flower farming), the cultivation of flowers and potted plants have gained prominence in the emerging markets of orchids, bromeliads among others (Junqueira and Peetz 2014). Considering the great genetic diversity of native species in Brazil, one strategy to leverage the national sector and make it self-sufficient is to establish Brazilian plant breeding programs for flowers and ornamental plants (Cardoso 2013); which makes it possible to obtain hybrids that are more adapted to our climatic conditions (Faria and Colombo 2015) and reduces the dependence on importation of Asiatic hybrids. There have been few studies on breeding orchids due to the long cycle of plants in the Dendrobium genus i. e., which leads to an average flowering development of three to four years (Vichiato et al 2014). Faria et al (2009), Faria et al (2011), and Faria et al (2013), working with Dendrobium crosses, were successful in obtaining three new cultivars (UEL 6, UEL 7 and UEL 8), which expressed the desired characteristics of mother plants such as flower size, flower coloration, flourishing period, number of flowers, plant height, among others. Faria et al (2015) obtained a hybrid of Oncidiuns which, besides presenting desirable agronomic characteristics for a hybrid, gave more balance and symmetry to the flowers, between the floral whorls
