Abstract
Abstract The effect of colchicine on the androgenic response of durum × bread wheat F 1 hybrids was studied. For this, three Greek durum wheat cultivars, exhibiting good yield and pasta quality, were crossed to two bread wheat cultivars with good response to anther culture. Spikes of the resulting hybrids, containing microspores in the mid to late uninucleate stage, were selected and cultured on two different media (W 14 and solid potato‐2) with and without colchicine. A negative effect on anther culture response was observed when colchicine was added to the W 14 induction medium. A similar effect was observed in two of the hybrids when they were cultured on to potato‐2 induction medium. In both induction media, green plant production was influenced negatively by colchicine treatment. The same was observed in albino plant production. The results of the present study support the view that anther culture response is strongly genotype dependent. Finally, potato‐2 induction medium was the most suitable one for the material studied.
