The Phenotypic change of wild-type blue or blue-violet to pink color in petal and stamen hair cells of Tradescantia is often used as a measure of genetic damage produced by physical and chemical mutagens. Although cytological analyses of Tradescantia are numerous due to the unusually large chromosomes of this genus, self incompatibility, low germination and the length of generation time have made classical genetic studies of flower color very difficult. However, the importance of the Tradescantia test system in detecting chemical mutagens at low concentrations has made it equally important to provide an adequate description of the genetic transmission and segregation of the genes controlling flower color. To date, three flower colors of Tradescantia have been investigated chiefly with chromatography and spectrophotometry techniques. The present work proposes a model for white flower color and provides further genetic information on three flower colors, namely violet, pink and plum.
