Resistance to Rust and Late Leafspot Diseases in Some Genotypes of Arachis hypogaea

Resistance to rust (Puminia arachidis Speg.) and late leafspot (Cercospridium personaturn (Berk. & Curt.) Deighton) in some peanut genotypes was studied under field conditions. Late leafspot development was also assessed in the glasshbuse 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 diseaseresistance in a breeding program
