Vaccaria pyramidata belonging to Caryophyllaceaea family is generally known in Turkiye as a weed and host plant for chickpea green larva. However, it has been used in medicine and cut flower sector in the world because of its valuable proteins and esthetic flowers. Vaccaria pyramidata resembles to Gypsophylla due to its natural plant habitus. But, it has larger, striking, pink flowers and seems feasible to improve better varieties through breeding. Also, it is thought that it may be used in Gypsophylla breeding. In the preliminary studies made with the seeds of wild germplasm which was found at high elevations with cool climate conditions, it was realized that Vaccaria pyramidata adapted to low elevations with hot climate and has a very high regeneration capacity in vitro in regard to callus induction, multiplication and rooting. The objective of this study was to establish in vitro regeneration system of Vaccaria pyramidata. For this aim, initially immature seeds were used as explant. The most striking two improvements in the seedlings as soon as germination began were a dense hairy root development and in vitro flowering in the aging period. Additionally, a dense proliferation and rooting were observed when the shoot tips and single nods of these in vitro seedlings were cultured.
