| Popis: | Blast (Magnaporthe grisea) and rust (Puccinia substriata var. indica) are the two important foliar diseases of pearl millet (Pennisetum glaucum (L.) R. Br.) that can be best managed through host plant resistance. For identification of diverse sources of blast and rust resistance, 305 accessions of Pennisetum violaceum, a wild relative of pearl millet, were screened under greenhouse conditions against five pathotype-isolates of M. grisea and a local isolate of P. substriata var. indica collected from ICRISAT farm, Patancheru, India. Based on the mean blast score (1 to 9 scale), 17 accessions (IP 21525, 21531, 21536, 21540, 21594, 21610, 21640, 21706, 21711, 21716, 21719, 21720, 21721, 21724, 21987, 21988, and 22160) were found resistant (score ≤3.0) to all five pathotypes, and 24 accessions were resistant to four pathotypes of M. grisea. As there was variability for rust resistance within some accessions, individual rust-resistant ( |
