In vitro regeneration of tomato cultivars

Petya K. Christova

Abstract: The potential for in vitro regeneration of three tomato cultivars using two types of culture media (Rm and Rtaz) was investigated. Two of selected tomato cultivars are cherry type (Aztec and Idul), whereas one of them is indeterminate variety (Buffalo heart). Results showed that the regeneration efficiency varied from 21% to 57%, depending on the cultivar and type of medium. The variety Buffalo heart demonstrated highest potential for regeneration on both cultivation media (50% on Rm and 57% on Rtaz). The lowest regeneration efficiency was counted for variety Idul (21% on Rm and 25% on Rtaz). The impact of the media used on regeneration potential is most significant for the variety Aztec (45% on Rm and 25% on Rtaz).
