Sub Clover
Trifolium subterraneum ssp. brachycalycinum

ANTAS is a black seeded Sub clover. It was derived from elite Sardinian germplasm and therefore is well suited to Mediterranean and temperate climates.

ANTAS demonstrates a prostrate to semi-erect growth habit and persists well on various soil types. It has mid to late season maturity and is suited to medium to high rainfall environments, with a growing season of 7 months.

ANTAS has been developed as a superior alternative to Clare, with improved hard seed levels and excellent herbage production. These attributes combine to make ANTAS suited to either permanent pasture or medium-term cropping rotations. ANTAS will also provide the benefits of soil nitrogen as well as providing an effective disease break.
