Variety description

10 August 2026

The Spanish rice variety Esperanza was bred with the goal of increasing productivity and lodging resistance in the conditions of the Ebro River delta. The main morphological features of the company's selection, which includes this variety, are aimed at creating plants with a lower height and a thicker stem capable of supporting a heavy panicle.

The Bolivian variety named Esperanza was derived from the synthetic population PCT-4 and is intended for rainfed farming conditions. Due to the presence of different varieties under the same name, differentiation of data by country of origin is required in agronomic literature.
