Background: Foxtail millet cultivation inIndia’s North Eastern Hill regionholds promise due to its adaptation to diverse environments and high-quality grain. The objective of this study was to assess the amount of variability present among the genotypes, association of traits and find out foxtail millet genotypes that produce high yield in diverse environments. Methods: The investigation was carried out during July 2022 to May 2023 in four different dates of sowing. Two environments maintained under rainfed condition and the remaining two environments are maintained under irrigated condition. The experiment was conducted in randomized complete block design with three replications in all environments. Result: Analysis of variance revealed statistically significant differences (at 5%) among the 30 genotypes for all yield variables under evaluation. Genotype ‘G1’ exhibited superior performance for both yield and yield-related traits. The present study revealed considerable genetic variation among the yield traits, with all traits demonstrating high heritability except for harvest index.Traits such as fodder yield per plant, panicle length, biological yield, flag leaf width, peduncle length, panicle width and grain yield per plant show high heritability coupled with high genetic advance. A strong correlation was observed between grain yield per plant and several traits including days to 50% flowering, days to maturity, plant height, panicle length, flag leaf length, peduncle length, biological yield and fodder yield per plant. This correlation was consistent at both the genotypic and phenotypic levels. Biological yield exhibited the strongest direct influence on grain yield per plant, followed by harvest index, flag leaf width and number of base tillers on genotypic and phenotypic levels.
