Grain yield losses in maize due to Late Wilt and Turcicum Leaf Blight in Maize (up to 100%0 (Jain and Kothari, 1983), (29-91%) (UIIstrup, 1952) have been reported. Both these diseases are considered as the major diseases on maize crop in peninsular India including Andhra Pradesh (Anon, 1988). Hence and effort was made in the present study to collect information on the variability and heritability parameters for late wilt and turcicum leaf blight resistance in some of the selected maize parental lines known for their good combining ability and agronome characters under artificial maculated conditions.
