Abstract
A susceptibility ratio for identifying and rating resistance is suggested and compared with the present method under natural conditions of infection in the field. This ratio brings out rolative resistance as susceptibility of a test variety; the advantage is that rating for each variety remains stable under varied conditions of natural infection. According to the suggested system susceptibility ratios of 0.14 and 0.35 are regarded as resistant and moderately resistant respectively. Four models of visual resistance scale are prepared to directly denote susceptible, resistant and moderately resistant reactions under different disease pressures
