Although the seeds of pepino plants are fertile and produce vigorous offspring, this crop is primarily propagated by cuttings (Heiser, 1964; Anderson, 1979; Morley-Bunker, 1983), and as a consequence, its genetic structure could be different from that of seed-propagated crops.
Kuigi pepiino seemned on viljakad ja annavad elujõulist järelkasvu, paljundatakse taimi peamiselt pistikute abil (Heiser, 1964; Anderson, 1979; Morley-Bunker, 1983), mille tulemusel nende geneetilised omadused võivad olla erinevad seemnetest paljundatud kultuuridest.
