THE IN VITRO MULTIPLICATION OF EBA POTATO CULTIVAR

Abstract

Solanum tuberosum cv. Eba was cultivated in vitro. The Regeneration capacity, organogenesis and multiplication of shoot tips and nodal explants have been studied on different culture media. The percent of regeneration was 60% after 2 weeks of in vitro culture. Shoot multiplication and complete organogenesis were obtained on all media containing cytokinins, but on the media supplemented with 2 mg/l Zeatine (V6) all the parameters showed superior values in the case of regeneration from shoot tip explants in comparison with nodal explants. In vitro microtuberization was also obtained on all media, the best results being obtained on V6 medium (in average 10-11 microtubers/explant).
