Genome revealed by SRAP markers

New study on genetic diversity of dianthus plants

Dianthus is a valuable genetic resource for flower breeding. However, study on the genetic similarity of Dianthus plants is rare. In this work, 20 pairs of SRAP markers were used to analyze genetic diversity of 44 Dianthus plants, including 13 lines of wild Dianthus chinensis L., 7 lines of wild Dianthus superbus L. and 24 commercial varieties including Dianthus caryophyllus L., Dianthus plumarius L. and Dianthus barbatus L.

Results showed that precise interspecific and intraspecific genetic diversity was provided in Dianthus plants by using 20 pairs of SRAP molecular markers. The interspecific genetic diversity of Dianthus plants was much abundant and the intraspecific genetic difference of wild Dianthus species was related to their geographical distribution and habitats. In this work, theoretical basis and technical support were provided for crossbreeding and molecular mechanism research of Dianthus plants.
