    Abstract : Med målet att utvärdera en mindre restriktiv teknik för genmodifiering i sötpotatis (Ipomoea batatas), både gällande ekonomiska begränsningar såväl som det tid och energi bemödande som ett sådant projekt oundvikligen påbrår, har vi arbetat flitigt med att etablera optimerade parameters för protoplast isolation och fortsättningsvis också utforskat lovande protokoll för transformation och regeneration av dessa protoplaster, för att slutligen framställa nya genotyper. Således har en extensiv litteraturundersökning av tidigare publicerade protokoll, varav explantor från sötpotatis men också relaterade arter inom Solanales ordningen har diskuterats, utfärdades varefter datan analyserades via diverse avancerade statistiska modeller.
