Evaluation of black rice genotypes reveals reduced flowering and grain quality under water deficit, indicating sustainable production opportunities.

To assess the performance of black rice genotypes under water deficit conditions and evaluate genotype-environment interactions.
Evaluated nineteen black rice genotypes and one white cultivar over three years
Conducted trials under traditional flooding and non-flood irrigation conditions
Assessed agronomic traits, yield, and grain quality traits
Black rice genotypes showed reduced flowering and lower grain quality under non-flood irrigation
Average yield of black rice was 31% lower than the white cultivar
Strong genetic correlations found between grain yield and morphological traits

Brunet-Loredo et al. (2025) studied this question.
