- Observation Panicle type showed the lowest genetic diversity index (H′ = 1.383) among the traits.
- Observation Green panicle color was predominant (84.78%) among the accessions.
- Observation Long panicle branch length was predominant (63.04%) among the accessions.
- Observation Lateral panicle type was predominant (71.74%) among the accessions.
- Observation Yellow grain color was predominant (86.96%) among the accessions.
- Observation Grain yield had one of the highest coefficients of variation (15.00%) and substantial genetic diversity (H′ = 2.11).
- Observation Grain weight per panicle had one of the highest coefficients of variation (14.61%) and substantial genetic diversity (H′ = 2.12).
- Association Grain yield was significantly positively correlated with grain weight per panicle (r = 0.901, P < 0.01).
- Association Grain yield was significantly positively correlated with main panicle length (r = 0.863, P < 0.01).
- Observation Combined analysis of variance revealed highly significant genotypic effects for all agronomic traits.
- Observation Genotype by environment interaction effects were non-significant for all traits.
- Observation Broad-sense heritability of grain yield was very high (H² = 0.998).
- Observation Broad-sense heritability of grain weight per panicle was very high (H² = 0.996).
- Observation Stepwise regression identified grain weight per panicle and main panicle length as the primary yield predictors (R² = 0.91).
- Observation Cluster analysis identified three groups with distinct trait profiles suitable for dual-purpose breeding, early-maturing cultivar development, and forage breeding.
- Observation The evaluated proso millet germplasm possesses substantial genetic diversity useful for breeding parent selection.
