The existence of a mutant form of one or more minor alleles in the endosperm that contributes in starch synthesis distinguished modern sweet corn from other maize. Current study was performed to identify diverse genotypes for developing good hybrid and exploit heterosis. This study also aimed to identify diverse material for prebreeding as an objective of maize improvement. In this experiment Mahalanobis D2 multivariate technique was used to calculate diversity. Highest distance of 1546.34 was observed between 1820197/T1 and 1820196/T2 while lowest distance of 28.66 was observed between 1820193/T2 and 1820195/20 genotypes. Similarly, Cluster V had greater intra cluster distance indicated the highest diversity. Cluster II and Cluster VII had highest distance provide the genotypes for pre breeding and help to improve sweet corn.
