Abstract

Rust caused by Puccinia substriata var indica is one of the major diseases affecting both forage and grain production in pearl millet, particularly in the postrainy cool season (rabi) crop. The disease can be best managed through host plant resistance. In all, 214 advanced breeding lines, including 126 designated B-lines, 23 designated R-lines and 65 potential R-lines were evaluated for rust resistance in the disease nursery during the postrainy season 2008–09 under natural epiphytotic conditions. Eight lines (1 B-line, 7 R-lines) that showed resistance (≤10% rust severity) in the field screen were evaluated in the greenhouse by artificial inoculation of potted seedlings to confirm their resistance. One B-line (ICMB 96222) and three R-lines (ICMR 0699, ICMP 451-P8 and ICMP 451-P6) were resistant while the other four R-lines were susceptible. The four confirmed resistant lines could be useful resistance sources for breeding rust resistant hybrid parental lines and their hybrids.
