Not AvGenetic variation is prerequisite for any crop improvement program as it helps in development of superior recombinants. Forty eight genotypes were evaluated for agronomic traits, yield and characters related to Al tolerance. The components of variability revealed high magnitude and highly heritable nature of the variations. High heritability with high to moderate value of genetic advance over mean was exhibited by majority of morphological traits used in the study. Significant correlations were observed for aluminum tolerance related traits, agronomic and yield traits. Principal components analysis revealed that the first three most informative components accounted for 70 % of the variance. The clustering pattern as revealed by dendrogram, based on average distance, classified the accessions into five clusters. Several high performing genotypes namely, N-861, Khougjai Phou, Posimot, Aaha and Epyo were found in the study which can be used for future breeding purposes.ailable
