High frequency direct shoot regeneration from Kazakh commercial potato cultivars (original) (raw)

Potato (Solanum tuberosum L.) is the third most economically important crop in the world and has a high nutritional value. In this study, the in vitro culture response of four widely grown in Kazakhstan potato cultivars, Astanalyk, Monument Kunaev, Tokhtar, and Aksor, was investigated using stem and leaf explants. Published protocols were evaluated and optimized to develop a more efficient protocol for the regeneration of plants from local potato cultivars in tissue culture, which is a prerequisite to facilitate potato genome modification. The explants were cultured on solid Murashige and Skoog medium supplemented with different concentrations and combinations of zeatin, 6-benzylaminopurine (BAP), gibberellic acid (GA3), 1-naphthaleneacetic acid (NAA) and indole-3-acetic acid (IAA). The maximum regeneration was induced from the stem internodal explants. A significant effect of the explant source on direct regeneration was confirmed with statistical analysis. The number of shoots obt...
