RESISTANCE TO Colletotrichum lindemuthianum IN INBRED COMMON BEAN LINES FROM THE OURO NEGRO X MEIA NOITE CROSS

摘要

Anthracnose, caused by the ftingus Colletotrichum lindemuthianum, is one of the most serious diseases of common bean {Phaseolus vulgaris L.). The main anthracnose control strategies include the use of healthy seeds, fiingicides and resistant cultivars. The use of resistant cultivars is the most efficient strategy, because it is environmentally safe and cost-effective in controlling the disease. However, this fungus has a large number of physiological races (Barcelos et al. 2011). Thus, resistant cultivars often become susceptible in a few years after being released, leading breeders to a constant search for new breeding lines with broad resistance to the fiingus. The aim of this study was to characterize the reaction of inbred lines from the Ouro Negro x Meia Noite cross derived from the common bean breeding program of the Federal University of Vigosa to races of C. lindemuthianum frequently found in the state of Minas Gerais, Brazil.
