SF Rouse

Improved forage yields and regeneration

SF Rouse is a midseason to late flowerng ssp. yanninicum cultivar. It is a replacement for Gosse and Napier with a flowering time between them but superior field performance. It has higher forage yield, especially in autumn/winter, higher seed yields and higher seedling regeneration densities than Gosse. It also has higher resistance to both Races 1 and 2 of clover scorch disease and to leaf rust than Gosse.

SF Rouse is well adapted to moderately acidic (pH CaCl2 4.5-6.5) soils prone to waterlogging and 550- 900 mm annual rainfall and where the growing season extends to mid-late November.

Agronomic features:
  • Sub species yanninicum (cream seeded)
    • Tolerant of water-logging
    • Well suited to flood irrigated hay production

  • High seed yields
    • Higher seedling regeneration in years 2 and beyond
    • Higher autumn/winter yields from more plants

  • Mid-late flowering
    • Produces more feed in high rainfall zone
    • Will re-seed in early season finishes

  • Moderate hard seed levels
    • Protects against seedling losses with false breaks
