Identification of new stock Matthiola incana

Garden stock [Matthiola incana (L.) R. Br.] is a commercially important horticultural crop thanks to its ornamental effect. Different stock cultivars vary in color and shape. An especially flowered phenotype is an essential index for evaluating its commercial value because double-flowered individuals have more brilliant flowers than single-flowered ones.

The present work aims:

  • to make superior cultivars with different colors, high fertility, being capable of early selecting only double-flowered seedlings by leaf color, and to investigate morphological characteristics
  • to select RAPD and ISSR primers for the cultivar certification and identification to culture and produce good commercial stock cultivars.

Here, in this study, new stock cultivars were obtained with different colors, including pink, pale pink, and white, through outcrossing between the “white” cultivar (high fertile but unable to select double flower phenotype) and “pink” cultivar (vice. versa).

Among newly obtained stock cultivars, single and double-flowered seedlings are distinguishable from single ones by leaf color, having about 70% of fertility. Moreover, RAPD and ISSR markers selected in this study can be applied to identify different stock cultivars in seed production, and culture and to establish a cultivar certification system.
