Description	Mitotic polyploidization in vitro was used in selected wild Solanum species and S.tuberosum dihaploids. Oryzalin was more effective than colchicine (P = 0.1). The rate of non-affected to mixoploid to tetraploid regenerants was 22 : 2.5 : 1 (colchicine) and 14 : 2 : 1 (oryzalin). Optimal concentrations and durations were 3.5 mm/24 h for colchicine and 25 or 30 mu m for 24 or 48 h for oryzalin (variations in concentration and duration are necessary owing to possible diversity of responses in selected genotypes). Tetraploids were obtained from S. berthaultii, S. bulbocastanum, S. pinnatisectum, S. verrucosum and eleven S. tuberosum dihaploids. The yield of tetraploids derived from tbr dihaploids was lower than that from the wild species (P = 0.01). Tetraploid regenerants were tested in intra- and inter-specific crosses. Three of 43 intra-specific combinations were successful and yielded 440 seeds. Inter-specific crosses yielded 48 seedless berries.
