Factors Associated with Resistance to Puccinia arachidis

Peanut rust infection frequency, uredial size, incubation period and latent period was studied on 47 genotypes. Seventeen genotypes namely NCAC 17133-RF, PI,259747, PI,393643, PI,381622, PI,390593, PI,390595, PI,393517, PI,405132, J-11, Jh-352, 39–2, J1–24, 2704, US-74 and MK-374 showed a lower infection frequency and smaller uredosori, longer incubation and latent periods.
