Abstract:
The present investigation was carried out at laboratory of Department of Seed Science and Technology OUAT Bhubaneswar. To identify aromatic short grain rice varieties by using modified phenol. In the present study, among thirty aromatic short grain rice varieties twelve aromatic short grain varieties reacted positively whereas remaining eighteen aromatic short aromatic grain rice varieties reacted negatively to modified phenol test. Based on modified phenol test, the aromatic short grain rice varieties were classified in to five groups as no change in colour (V₃, V₄, V₆, V₇, V₁₁ V₁₃, V₁₅,V₁₆, V₁₇, V₁₈, V₂₀, V₂₁, V₂₄, V₂₅, V₂₆, V₂₇, V₂₈ and V₂₉) light brown (V₅ and V₁₄), brown (V₁₂), dark brown (V₁₀ & V₂₂) and Black (V₁, V₂, V₈, V₉, V₁₉, V₂₃ and V₃₀). Thus, based on the colour reaction of palea and lemma of seeds to Modified phenol test can be effectively distinguished.
