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
