Variety description

10 August 2026

The SJKK line was obtained by gene pyramiding using molecular markers. Its genotype includes four genes for resistance to rice blast: Pib, Piz, Pik, and Pita. The varieties Katy, Saber, Jefferson, and Kusabue were used as initial donors in the creation of the line.

This line possesses complete resistance to rice blast, confirmed in field and greenhouse trials. Information on morphological traits, such as plant height or maturity group, is not provided, as the object is a donor of genetic material, not a commercial variety for grain production.
