The present study aimed to assess the genetic variability, heritability, and genetic advance for nine yield and yield- attributing traits in 30 genotypes of brown top millet (Brachiaria ramosa (L.) Stapf.) maintained at Agricultural Research Station, Perumallapalle during Rabi 2024-25. Significant differences among genotypes were observed for all traits, indicating substantial genetic variability in the material studied. High genotypic and phenotypic coefficients of variation were recorded for number of productive tillers per plant and grain yield per plant, suggesting ample scope for improvement through selection. Traits such as test weight, number of productive tillers per plant, harvest index and grain yield per plant exhibited high heritability coupled with high genetic advance as a percentage of mean, indicating the predominance of additive gene action and the effectiveness of phenotypic selection for these traits. The findings highlight productive tillers per plant, grain yield, harvest index and test weight as ideal targets for genetic improvement in brown top millet breeding programmes. Integrating variability measures with heritability and genetic gain estimates is emphasized for formulating effective breeding strategies.
