Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This report investigates the optimization of callus induction and transformation protocols for selected traditional Sri Lankan rice varieties using Agrobacterium mediated transformation. The study aims to enhance the efficiency of gene transfer and establish a reliable method for unlocking the valuable traits, such as pest resistance and nutritional value, inherent in these traditional varieties.

• Callus induction efficiency and its dependence on genotype.
• Optimal hormone concentrations for callus induction in various rice varieties.
• Evaluation of Agrobacterium-mediated transformation efficiency in diverse traditional rice varieties.
• The potential of Agrobacterium-mediated transformation for genetic modification in Sri Lankan rice varieties.
