Abstract

The possibility of obtaining tetraploids from diploid yellow-flowered cyclamen 'Kage Yellow' through colchicine treatment and the effects of polyploidization on the characteristics of yellow-flowered cyclamen were investigated. A 4-day treatment of tuber segments with 100 mg l-1 colchicine in vitro yielded two tetraploid plants. The petals of the tetraploids were larger and had a greater ability to accumulate chalcone than those of their diploid relatives. Polyploidization may therefore represent a useful method for the commercial breeding of deeper yellow-flowered cyclamen.
