Key Points

The aim is to develop a rice variety that is both high-yielding and has excellent eating quality suitable for export.
Developed 'Shine Pearl' by hybridizing 'Nishinan 136' and 'Etsunan 227'.
Registered the variety in April 2022.
Conducted taste tests and comparisons with 'Koshihikari' and 'Ikihikari'.
Evaluated resistance to lodging and diseases.
'Shine Pearl' shows a yield 23% higher than 'Koshihikari' and 4% higher than 'Ikihikari'.
Taste tests rated 'Shine Pearl' equivalent to 'Koshihikari'.
Expected production of approximately 880 tons in 2024, all for export.

Implication

Breeding of a high-yield, export-quality rice variety highlights agricultural sustainability in Japan.
