The genus Stylosanthes contains over 40 species of tropical and subtropical pasture legumes. Two cultivars, Mineirão and Reyan II, have been particularly successful due to their resistance to the fungal disease Colletotrichum gloesporioides. Research is ongoing to evaluate new Stylosanthes species for agronomic traits like yield, drought tolerance, and disease resistance in order to develop improved cultivars for sustainable pasture systems in tropical regions.

3. The genus Stylosanthes with about
forty-four species and sub-species is an
important source of pasture legumes for
tropical and subtropical environments

most of the available
cultivars, were devastated
by Colletotrichum
