V raziskavi je bil izveden poljski poskus za ovrednotenje in primerjavo učinkov sajenja s semeni in stebelnimi potakjenci dveh linij kitajske vinje (IT07K-243-1-2 and IT07K-298-15). Podatki ocene so bili podvrženi študentskemu t- testu, da bi ugotovili značilne učinke dveh metod razmnoževanja na ravni p < 0,05. Rezultati so pokazali, da so bili rastni parametri kot so višina rastlin, število listov, listna površina, nadzemna suha masa, indeks listne površine, razmerje med listi in površino tal, relativna prirast, neto asimilacija in rast pridelka značilno večji pri razmnoževanju s semeni v primerjavi s stebelnimi potakjenci. Komponente pridelka kot so število zrelih strokov na rastlino, masa strokov na rastlino, dolžina strokov, obseg strokov, polnjenje strokov, masa 100 semen, masa semen na rastlino, poprečno število semen na strok, žetveni indeks in pridelek strokov na kvadratni meter so imele podoben vzorec kot je bil zabeležen pri rastnih parametrih. Potencial kalitve pridobljenih semen kot tudi njihova vitalnost sta bila boljša pri semenih sejanih rastlin kot pri tistih iz potaknjencev. Razlika v različicah je pokazala, da je imela linija IT07K-298-15 večjo rast, večji pridelek in potencial kalitve kot linija IT07K-243-1-2, a je bila vsebnost beljakovin, maščob in ogljikovih hidratov pri slednji večja od normale. Na osnovi raziskave lahko zaključimo, da so imele rastline vzogojene iz semen večjo produktivnost. Kljub temu pa lahko vzpodbujamo vzgojo rastlin iz stebelnih potakjencev zaradi neznačilnih razlik med nekaterimi zgoraj naštetimi parametri in s tem zmanjšamo odvisnost od semen kot glavnega vira razmnoževalnega materiala kitajske vinje.
