The present investigation was carried out to know the genetic diversity among the new inbred lines of maize during Kharif 2011. In this experiment, seventy nine inbred lines and three checks were evaluated and observations were recorded for thirteen quantitative traits. Analysis of variance revealed that highly significant difference among all inbred lines. Inbred lines were grouped into fourteen clusters, indicating the presence of genetic diversity. The cluster I is having highest number of genotypes (67). The maximum inter cluster distance was observed between clusters II and XII (22.41) and highest intra cluster distance was in cluster XII (5.46) and also wide range of variation was observed in cluster mean performance for the characters studied. These genetically diverse inbred lines can be further used for developing superior hybrids and can also be utilized in developing synthetics and composites.
