Abstract:
Hundred groundnut genotypes were subjected to field screening during kharif 2016 and 2017 for rust and late leaf spot reaction using spreader row technique in which the disease susceptible genotype (SBXI) was sown at regular interval after 10 test genotypes in Augmented design manner. Response of genotypes on disease severity of leaf spots and rust were scored at 80 and 90 DAS using a modified 1-9 point scale (Subrahmanyam et al., 1995). None of the genotype except Phule Unnati was rust or late leaf spot resistant since high levels of resistance to late leaf spot and rust were often reported in wild peanut species and one of the parent which was used in development of Phule Unnati was wild species. ICG-4406, ICG-4494 and ICG-9064 were moderately resistant to both rust and late leaf spot diseases whereas, ICG-5001, ICG-5320, ICG-8062 and ICG-8353 were moderately resistant to only late leaf spot disease.
