The investigation was undertaken to examine the genetic variability present in the 17 fieldpea genotypes, grown under protected irrigation at the marginal soils of foothills of Manipur. The significant variability was recorded for traits except days to 50% flowering. In PCA, there are two eigen values greater than 1 implied the choice of the two principal components (PCs) and the first and second PCs had 60% and 18% of the total variance, respectively. The 1ˢᵗ PC was strongly influenced by characters like plant height, days taken to attain 50% flowering, maturity and pods/plant, whereas 2ⁿᵈ PC was largely influenced by seed yield and 100 seed weight. Genotype “HFP 9426” was found superior based on both PC1 and PC2. The genotypes arranged in bipolar plane clearly exhibited that pods/plant, days to 50% flowering and maturity were with greatest length and directly helped to determine the level of Agro-morphological diversity. Cluster analysis generated three distinct groups of the genotypes studied here.
