Golden rice is a transgenic crop of the future with the following improved trait -

  1. High lysine (essential amino acid) content
  2. High protein content
  3. Insect resistance
  4. High vitamin A content

Answer

(4) High vitamin A content

Solution

As per NCERT, genetically modified crops have been made with enhanced nutritional value of food, e.g. golden rice, i.e. Vitamin 'A' enriched rice.

⇒ Golden rice carries genes for the synthesis of β-carotene (provitamin A), which gives the grain its golden-yellow colour.

∴ The improved trait of golden rice is high vitamin A content.
