Abstract Following PEG and high pH induced fusion, intraspecific gametosomatic hybrid plants (pollen tetrad protoplasts of a normal purple flowered variety of P. hybrida fused with cell suspension protoplasts of a nuclear albino mutant of the variety Blue Lace) and interspecific gametosomatic hybrid plants (tetrad protoplasts (as above) fused with cell suspension protoplasts of a nuclear albino mutant of P. parviflora) were recovered. Hybrid plants of both combinations possessed an intermediate vegetative and floral morphology with chromosome numbers of 2n=3x=21 and 2n=3x=25 respectively. Hybrid cells were in both systems identified as green colonies against an albino background as a result of complementation to chlorophyll proficiency. Pollen tetrad protoplasts did not divide. The production of such plants at the intra- and interspecific level in Petunia has shown that the concept of gametosomatic hybridisation can be extended to genera other than Nicotiana. An alternative selection strategy is available to that as used earlier for Nicotiana.
