Abstract

A total of 116 peanut (Arachis hypogaea L.) genotypes, which included all market types, were evaluated for resistance to late leafspot (Cercosporidium personatum Berk, and Curt. (Deighton)) in three tests during 1986. Two tests were conducted in greenhouses at Gainesville and Quincy, Florida. The third test was conducted in the field near Marianna, Florida. Lesion number per leaf, percent leaf necrotic area, lesion diameter, spore production, and latent period were evaluated. Correlations were calculated between greenhouse and field studies. Contributions of each component of resistance to an overall plant appearance score was also determined.
