Description
Endophyte-infected (E+) tall fescue (Festuca arundinacea Schreb.) has enhanced fitness in some environments. The objectives were to measure the effects of the endophyte Acremonium coenophialum on seed yield traits and to determine the transmission rate of the endophyte from infected maternal plants into seed. Twenty infected and noninfected (E-) seedlings of each of three tall fescue cultivars were transplanted to the field in May, 1993. In 1994, there were significant differences between E+ and E- plants for panicle number and seed weight per panicle. In the second year, there were no differences between E+ and E- for the measured traits. Cultivar effects were larger than endophyte effects in both years. Endophyte transmission was very high in both years.
