Pointed ear with the scientific name of Stachys Setifera belongs to the plant family Lamiaceae that has a relatively wide distribution in Iran and grows in humid areas with high morphological diversity in leaf shape, type of crack, flowers and inflorescence size. Because few studies were hold about genetic diversity and identifying superior genotypes of the plant in terms of morphology and crossability, the aim of this study was to investigate these cases and to evaluate plants in the production of seeds for the next generation of superior genotypes. For this purpose, 10 genotypes from Isfahan, Shahrekord, Hamedan, Tehran and Kelardasht were collected and evaluated in a randomized complete block design with 3 replicates. The results of self- and cross pollination of genotypes showed that genotypes collected from relatively humid and cold regions are more capable for seed production. Based on the results of analysis of variance, genotypes showed a high variation in most of the traits. The results of this study also showed a high positive correlation between some of the traits related to reproductive growth which may be effective on the type of pollination of the plant. In addition, there was a positive and high correlation between vegetative growth traits. Negative, low and nonsignificant correlation between vegetative growth and traits related to reproductive growth observed in this study could show no acceptable relationship between these two traits and also impossibility in improving both characteristics, simultaneously. The results of cluster analysis and principal components analysis also showed that the genotypes collected from cool and relatively cold areas of the country are more similar in terms of productive growth and might by crossing between them, a more variable population is produced. Investigating the diversity of this species and evaluating the offspring resulting from the crossing can increase the possibility of breeding this species and reaching a superior genotype.
