GM Brinjal Objective: Pest Resistance
The development of genetically modified (GM) brinjal, specifically Bt brinjal, aimed to address significant challenges faced by farmers due to insect pests.
Primary Objective Explained
The main objective for creating this GM brinjal was:
- To make it pest-resistant. This modification introduces a gene from the bacterium Bacillus thuringiensis (Bt) into the brinjal plant.
This Bt gene enables the plant to produce a protein toxic to specific insect larvae, particularly the destructive brinjal fruit and shoot borer. This reduces the need for chemical pesticides.
Evaluation of Other Options
- Increased shelf life: While desirable, this was not the primary goal of the Bt brinjal modification.
- Drought resistance: This trait requires different genetic modifications and was not the focus here.
- Improved taste: Taste improvement is subjective and was secondary to addressing the major pest problem.
Therefore, the core purpose of developing GM brinjal was to achieve resistance against damaging pests.
