Reproduction is the most important reproductive system used to produce and maintain genotypes of plants, especially in fescue (festuca arundinacea schreb.), Which is used for grass and forage production. Reproduction is one of the ways in which plants are specifically produced. Plant breeding creates pure lines that increase the selectivity of the additive effect. This experiment was conducted to investigate the effect of self and cross pollination on quantitative and qualitative traits in different tall fescue genotypes. The genetic material of this experiment consisted of 10 genotypes, self and cross pollinated in a completely randomized block design with three replications. At the time of clustering and before flowering, 10 ears of each genotype were covered with paper bags, and compulsory selfing was carried out, and other ears of the plant were released for free pollination. Plant height, number of ears, percentage of selfing, 100 seeds of selfing weight, 100 seeds of free pollination weight, seed yield per plant, planting weight, plant dry weight, day to clustering, day To pollination was evaluated. The range of variations for all traits except the 100-seed weight had a wide range, indicating a high variation among the genotypes examined. The highest range of variations related to the fresh weight trait was 162 to 442 grams. But for the weight of 100 seeds had a low range. The highest genetic and phenotypic variation coefficient was related to the number of seeds per ear and then the number of ears. The lowest genetic and phenotypic coefficients were related to day to clustering. The values of genetic variation coefficients were lower than the coefficients of phenotypic variation, which is due to environmental impacts. The low differences between the phenotypic variation coefficients and the genetic variation coefficients show that most of the observed diversity has a genetic origin and suggests that these traits are less affected by the environment, which allows for the selection of desirable genotypes in selfing mode Correlation results showed that there was a significant positive correlation between fresh weight and dry weight (0.98). In cross pollinated mode correlation results showed that the highest positive and significant correlation was observed between fresh weight with dry weight (0.99) and day to clustering and day to pollening (0.94). The results of analysis of components showed that the first two components justify 72.83% of the varieties. The first component with the traits of fresh weight, dry weight, 100 seed weight and plant height had a strong relationship and proposed name for this component is performance indicator.
