Genetic diversity among six cultivars of rabi sorghum was studied by using 10 random primers. The total number of amplified PCR bands was 44 of which 30(68.18%) were polymorphic displaying PIC values ranging from 0.07 to 0.40 with an average of 0.30. Similarity coefficients among the genotypes ranged from 0.43 to 0.94. The similarity coefficient was used to construct a UPGMA based dendrogram using average linkage between groups. The analysis illustrates considerable potential of RAPD markers for estimating genetic diversity among six genotypes of rabi sorghum. The maximum genetic distance was found between the M-35-1 and Phule Rewati (0.43) while the lowest genetic distance was between Phule Vasundhara and Phule Vasudha (0.94). Selecting parents of diverse genetic base with contrasting phenotypes of various biotic and abiotic stresses for developing mapping populations for quantitative trait loci (QTL) detection and marker-assisted selection. RAPD markers used to reveal genetic diversity and variations within and among them the improved cultivars through the diverse gene pool for future breeding program.
