Avena sativa

WINTAROO is a hay variety developed by SARDI and commercialised by AEXCO in 2002. It was released as a replacement for Marloo.

WINTAROO is a tall, mid-season maturing hay oat with good early vigour. It resists brown leaf tipping by hot, northerly winds better than other varieties and is adapted to low, medium, and high rainfall locations. WINTAROO also has low grain hull lignin making it an option for feed grain.

WINTAROO maintains good colour longer than most varieties, so care is needed to assess the crop for optimum cutting time to ensure good quality.
