Ninety-eight percent of cotyledons of  Cucumis metuliferus  (PI 482439) regenerated shoot buds in 5 weeks on MS medium with 10 μ m  BA. Regeneration rates on agar gelled medium and liquid/membrane system were compared after weekly transfers of tissue from liquid/membrane to agar during the 5 weeks of regeneration culture. Number of shoots and buds increased from six (on agargelled medium) to nine per cotyledon when explant on liquid/membrane system for 3 or 4 weeks was transferred to agar gelled medium. Shoot development, rooting, and survival in greenhouse was adequate regardless of whether regeneration was initiated on agar or liquid/membrane system. Tetraploid regenerants were found to be about 9% of the almost 400 regenerants screened. Pollen morphology was a quick and definitive screening technique for tetraploid plants. Frequency of tetraploid plants was similar after 5 weeks of induction on either agar or liquid/membrane system. This frequency decreased by a factor of 10 following transfer of explants from membrane to agar after the first week of induction. Timing of this transfer plays a critical role in eliminating tetraploid variants.
