INTERSPECIFIC HYBRIDIZATION IN THE GENUS GLOBBA USING IN VITRO EMBRYO CULTURE
An interspecific hybridization had been carried out among four species of Globba, G. schomburgkii, G. magnifica, G. rosea and G. globulifera. Direct and reciprocal crosses were made. Two crosses, G. rosea × G. globulifera and G. rosea × G. magnifica, produced fruits in both direct and reciprocal crosses, whereas the other crosses produced fruits only in the direct crosses. An embryo rescue technique was used to obtain interspecific hybrids. Twenty days after pollination (DAP), embryos showed high percentage of germination for all crosses. A total of 71 interspecific hybrid plants were produced in 12 combinations. All hybrid seedlings obtained were successfully transplanted to soil and these seedlings grew normally. Interspeciﬁc hybrids showed distinct developmental potentials and characteristics.
