Quantifying rice-leaf blast BI genetic relationship via the receptivity factor

, : Quantifying rice-leaf blast BI genetic relationship via the receptivity factor. International Rice Research Newsletter 17(2): 9

A study of the receptivity factor (RF; number of lesions produced on the plant divided by the number of Magnaporthe grisea spores deposited on the plant) in the susceptible lowland rice varieties IR50 and IR72, the moderately resistant upland variety UPLRi5 and the resistant Kinandang Patong showed that RF values were highest in IR50.
