Sub Clover
Subterranean/Sub clover (ssp. yanninicum)

GOSSE is a large white seeded sub-clover variety that was developed as part of the National Subterranean Clover Improvement Program.

GOSSE demonstrates a prostrate to semi-erect growth habit and is particularly well suited to moderate to heavy soils and is able to tolerate short periods of waterlogging.

It has mid-season maturity which makes GOSSE suitable for medium to high rainfall zones. GOSSE was developed as a replacement for Trikkala and as an alternative to Larissa. It is suited to regions with a 7-month growth period. It was selected for improved seedling vigour, increased hard seed, disease resistance, and winter and spring herbage production. The superior hard seed levels of GOSSE makes it well suited to either permanent pasture or medium-term cropping rotations. GOSSE will provide the benefits of soil nitrogen along with an effective disease break.
