摘要：
The genetic stability of Solanum tuberosurn L. cv. Desiree plantlets obtained from embryogenic cell suspension cultures that were induced from mixoploidy calli tissue with abundant bi-nucleated cells was analyzed. Plants regenerated from these tissues showed an euploid number of chromosomes (2n=4x=48). This result indicates that in this system, euploid cells were selected to go through a somatic embryogenesis process and plant regeneration. Genotype stability of the regenerated plants was screened by RAPD analysis. The results indicated that the new plant population was highly homogeneous.
