Field evaluation of quantitative resistance to anthracnose in Stylosanthes scabra.

A field study was conducted for two successive growing seasons at the Southedge Research Station, Queensland, Australia, to evaluate and characterize the expression of a quantitative resistance in seven accessions of the tropical pasture legume Stylosanthes scabra to anthracnose caused by Colletotrichum gloeosporioides. These accessions had shown moderate to high levels of resistance to four isolates of the pathogen in earlier glasshouse studies. Five of the seven accessions showed moderate to high levels of resistance in the field (...)
