| Description |
The components of resistance to late leaf spot caused P. personata [Mycosphaerella berkeleyi] of five interspecific hybrid cultivars of groundnut, along with two susceptible cultivars, were determined during the rainy seasons of 1997-98 in greenhouse and field experiments conducted in Patancheru, Andhra Pradesh, India. All the interspecific hybrid cultivars showed significantly longer incubation and latent periods; lower lesion number and frequency; smaller lesion diameter; and less sporulation indices, leaf area damage and defoliation under both environments compared to the susceptible cultivars. Latent period, lesion diameter, sporulation index and defoliation were the major contributing components to the resistance of groundnuts to late leaf spot.
