Abstract

Regeneration of plants by caulogenesis of anther derived callus of Streptocarpus X hybridus ‘Concorde’ was obtained on MS basal medium with 2.0 mg/l NAA and 0.5 mg/l BAP. All regenerated plants were diploid and of somatic cell origin as determined by chromosome counts, flower color and morphological similarity to the anther donor plant, and flower color segregation among progeny of anther-derived plants. Variation expressed as deformed and dwarfed transient morphology was observed in 2 anther-derived plants. Variation was also observed among progenies of 5 anther-derived plants from the same anther donor plant for days to flowering, flowers per peduncle, peduncle length, and leaf area. Additional morphological variation including transient leaf variegation among seedlings and twisted or inverted leaves on mature plants was also observed among progeny of anther-derived plants.
