Selection of alfalfa genotypes for resistance to the foliar pathogen Curvularia geniculata

An. acad. bras. ciênc; 89 (3), 2017
ABSTRACT Foliar diseases impose severe restrictions on the persistence and productivity of Medicago sativa, both of which may be increased by developing disease resistant and more competitive genotypes that can improve pasture quality. We found Curvularia geniculata as the principal alfalfa foliar pathog...
