Callus induction and growth in transgenic potato genotypes

Abstract

The aim of this study was to establish an effective protocol for callus induction from the potato 
genotypes (Solanum tuberosum L.) used and to investigate whether the transferred oxalate oxidase 
enzyme or transformation procedure has any effect on callus induction of transgenic lines of cultivar 
Desiree and Maris Bard. The results showed that the effects of genotype and medium on measured 
characters were highly significant. In order to compare overall performance of transgenic lines of each 
cultivar with their parental cultivars (non-transgenic), orthogonal comparisons were used and indicated 
the significant differences between transgenic and non-transgenic genotypes. The significant 
differences between the cultivars and their transgenic lines expressing oxalate oxidase enzyme 
indicated that the transformation procedure had a significant effect on their callus induction and 
growth.
