Thirty sorghum germplasms were evaluated to assess the pattern of morphological variation through metroglyph analysis, at Sorghum Research Station VNMKV Parbhani, during 2015–16. Genetic variability in the genotypes was evaluated for five characters viz., plant height, number of leaves, 100 seed weight, grain yield/plant and fodder yield/plant. Mean values were used for analysis. The germplasms were then categorized in eight groups. Group V consisted of maximum number of genotypes followed by group IV. Germplasms falling in one group were closely related, while lines belonging to different genotypes exhibited wide variability. The germplasms falling in different groups can thus be used as parents in sorghum improvement programme. Genotypes IS-26530 and IS-23345 from two different groups were identified as important for sorghum improvement programme.
