Grain quality of rices grown in irrigated and upland cultures

Upland culture of nine varieties at Ivory Coast resulted in decreases in grain weight, brown and milled rice translucency, Chroma meter L* of rough rice, Chroma meter L* and b* of milled rice, milled rice protein, and Amylograph peak viscosity, and in increases in total phenolics of hull and brown rice, and Chroma meter a* of rough, brown, and milled rice of 5 to 8 of the varieties as compared with irrigated culture. Upland culture had no consistent effect on grain resistance to Angoumois grain moth (Sitotraga cerealella).
