Pearl millet blast resistance disease

Blast (Magnaporthe grisea) is an important foliar disease of pearl millet (Pennisetum glaucum (L.) R. Br.). A total of 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 were found resistant (score #3.0) to all five pathotypes (Sharma et al. 2020). In another study, 238 accessions of mini core accessions pearl millet were screened for blast resistance, and identified three accessions (IP 7846, IP 11036, and IP 21187) exhibited resistance to four of the five pathotypes (Sharma et al. 2012).
