Abstract
An Exacum hybrid, method to produce the hybrid plant, and progeny derived from the Exacum hybrid are disclosed. The Exacum hybrid is derived from an interspecific cross with Exacum taxa E. pedunculatum, E. macranthum, E. pallidum, E. trinervium and E. trinervium ssp. ritigalensis native to Sri Lanka. Also disclosed is a cell culture comprising regenerable cells obtained from the Exacum hybrid, a method of producing an Exacum hybrid from the regenerable cells, and an Exacum hybrid produced from the regenerable cells.

An Exacum hybrid derived from an interspecific cross with Exacum taxa E. pedunculatum, E. macranthum, E. pallidum, E. trinervium and E. trinervium ssp. ritigalensis native to Sri Lanka, the hybrids characterized as having a flowering time of about 80 to about 150 days, zinc efficient, a height of about 10 to about 30 cm, a leaf length of about 4 to about 13 cm, a leaf width of about 1.5 to about 4.0 cm, a flower size of about 2 to about 8 cm, a branching density of about 2 to 3 per 5 cm, over the length of the stem, and a vertical growth habit, and progeny derived therefrom.
A method for producing a hybrid Exacum by interspecific cross with Exacum taxa E. pedunculatum, E. macranthum, E. pallidum, E. trinervium and E. trinervium ssp. ritigalensis native to Sri Lanka, the hybrids characterized as having a flowering time of about 80 to about 150 days, zinc efficient, a height of about 10 to about 30 cm, a leaf length of about 4 to about 13 cm, a leaf width of about 1.5 to about 4.0 cm, a flower size of about 2 to about 8 cm, a branching density of about 2 to 3 per 5 cm over the length of the stem, and a vertical growth habit.
An Exacum hybrid characterized as comprising a stem shape that is cylindrical to quadrangular, with, or without wings or lines, with a height at anthesis of about 12 to about 36 cm, a leaf shape that is lanceolate to ovate or narrowly elliptic with a length from about 5.5 to about 11 cm, and a width from about 1.8 to about 3.7 cm width, a flower colour that is pale blue to dark violet and characterized with a Royal Horticultural Society of England (RHS) score of 89B-C through to 93A-C, a calyx lobe length of about 3 to about 24 mm, a petal apex arrangement that is rhomboidal to broadly obovate, overlapping or not, with a length of about 20 to about 28 cm and a width of about 16 to about 21 mm, and an anther length of about 8 to about 18 mm, and progeny derived therefrom.
