Genetics and propagation of Sobralia orchids

Abstract

Sobralia is a genus of terrestrial orchids native to the tropical regions of the Americas, distinguished by the fleeting yet striking beauty of its large and symmetrical flowers. Limited efforts have been made in plant breeding within this genus, resulting in most specimens being sourced from wild populations. Research conducted at Lankester Gardens indicates that in vitro seed germination rates are high, suggesting the potential for hybridizing and propagating species with advantageous traits such as extended flower longevity and fragrance. Future research may concentrate on the greenhouse acclimatization of tissue culture plants and polyploidization, aiming to establish a robust pipeline of hybrids exhibiting vibrant flower colors.
