Field and Greenhouse Evaluations of Pearl Millet for Partial Resistance toPuccinia substriatavar.indica

Pearl millet (Pennisetum glaucum) inbreds Tifs 383, 700481-21-8, and ICMP 501 were evaluated for partial rust resistance in comparison to susceptible inbreds Tift 23 DB. In field trials, area under the disease progress curves of the three inbreds were less than that of Tift 23 DB when disease pressure nerve. Uredinium dimensions on seedlings 10 days after inoculation were smaller for the three inbreds than for Tift 23 DB. Seedlings exhibited susceptible infection types when inoculated with four single-uredinium isolates except for a moderately resistant infection type 2 when ICMP 501 was inoculated with isolate PS89-775
