In order to study of variation and correlation between yields and yield components in Plantago ovate genotypes, an experiment was investigated through completely randomize design with 10 replications. Genotypes were evaluated for important traits of plant height, inflorescence height, spike height, number of fertile spikes, number of infertile spikes, total number of spikes, number of grains per spike, leaf height, leaf number, grain yield, biological yield and harvest index. On the basis of variance analysis results, the differences among genotypes were statistically significant for all traits. Cluster analysis based on the square Euclidean distance and Ward's method, classified génotypes in three clusters and the accuracy of the results of clustering using discriminant analysis was confirmed completely. According to the path analysis, biological yield had the highest direct effect on seed yield per plant.
