Seed traits are an important measure of the effects of endophytic fungi in Festuca genus. In this study, endophyte-infected (E+) and un-infected (E-) clones of the same tall fescue genotypes were used to investigate the effects of endophyte on the seed production and associated traits. Endophyte infection resulted in 32.8% increase of total seeds by weight, 34.6% seeds per plant, and 30.6% panicles per plant, but other seed components were not affected by endophyte. Significant phenotypic variances were observed for traits except for 1000 seed weight. Plant genotype×fungal status interactions occurred for seed per plant. These interactions occurred largely because of variation in different plant genotypes. Genetic variance for this trait in E+ was greater than E- for both years, suggesting that the endophyte can mask plant genotypic variance. The results indicated that endophyte had a positive effect on seed production but could result in overestimating of plant genetic variance for some traits. In conclusion, breeding strategies should consider presence or absence of endophyte and the possible effects on variances.
