Abstract

Resistance to rust (Puccinia arachidis Speg.) and late leafspot (Cercosporidium personatum (Berk. & Curt.) Deighton) in some peanut genotypes was studied under field conditions. Late leafspot development was also assessed in the glasshouse and the parameters lesion diameter, defoliation percentage and sporulation gave highly significant correlations with the field disease scores. Several genotypes were found to be resistant to both rust and late leafspot and should be useful sources of multiple disease-resistance in a breeding program.
