An interploid cross (conventional breeding) of SugarBelle® ‘LB8-9-9’ mandarin hybrid with a somatic hybrid of [Nova mandarin hybrid+Succari sweet orange], followed by embryo rescue, led to the recovery of the seedless triploid hybrid known as ‘C4-15-19’. This is the first triploid citrus hybrid released by the University of Florida that was fathered by a somatic hybrid produced years before via protoplast fusion. Trees of ‘C4-15-19’ are productive, producing an attractive peelable tangerine fruit with robust sweet flavor, maturing in October/November under Florida conditions. Fruit size is small-to-medium, and quite uniform.
