      Protoplasteilla tarkoitetaan soluja, joiden solunseinä on poistettu entsymaattisesti. Tällaisia soluja voidaan fuusioida yhteen, jolloin kahden eri perunalinjan yhdistelmästä muodostuu solujen kasvatuksen jälkeen somaattisia ...

    • Fluorescence in situ hybridization of potato somatohaploids and their somatic hybrid donors using two Solanum brevidens specific sequences
