An investigation was carried out to assess nature and magnitude of genetic diversity for grain quality traits and productivity traits in mini core collection of sorghum. Mini core accessions were grouped into 15 clusters, where in cluster III had largest with 21 accessions whereas cluster XIII had minimum with 5 accessions. Plant height contributed maximum divergence with . The inter cluster distance D2 value ranged widely with minimum values of (D2 =) and maximum value (D2 =) indicating high diversity among mini core and it was desirable to select mini core from clusters showing high inter cluster distance. | Genetic diversity and principal component analysis for grain quality and productivity traits in sorghum [Sorghum bicolor (L.)
