It is strong aromatic basmati type rice variety (according to GCMS system the value of volatile aromatic compound is 2.12 ppm), 29.2% amylose content with 8.9% protein content. Farmers can benefit financially from growing the premium quality enriched aromatic rice variety BRRI dhan104 and the total rice production will be increased along with possible to earn foreign currency by export this variety.
