An experiment was conducted to evaluate the genetic divergence in 93 inbreds of fodder maize through variability, D2 and principal component analysis. Observations were recorded on ten biometrical traits a quality trait. The variability analysis revealed higher GCV PCV for green yield per plant heritability coupled with high advance viz., height, leaf length plant. Hence, study indicated that direct selection above would be effective. Diversity sorted into eleven clusters. In case inter cluster distance, maximum distance obtained between clusters VIII X followed by VI XI indicating these pairs have more could utilized hybridization programme. D2analysis suggests GETM30, GETM84, GETM12, GETM81 distinct diversified classed as promising based mean divergence. These genotypes programme obtain heterotic hybrids apart from getting desired segregants later generations. According principle (PC) analysis, out 11 PC groups, four PCs than one Eigenvalue, which contributes 70.30% total variability. However, its attributing PC1, PC2, PC3 PC4 hence, scores components further enhance biomass maize.
