Variety description

10 August 2026

The variety is a well-known elite form of American breeding. In agronomic research, it often serves as the base genetic background for the introgression of beneficial genes from wild relatives of the species Oryza rufipogon for the purpose of developing lines with increased yield and improved performance metrics.

Morphologically, the variety belongs to the long-grain type. In scientific experiments, it is used as a standard for comparison when evaluating biomass, rate of phenological development, and grain quality. Studies also examine the variety in the context of investigating mechanisms of resistance to rice blast.
