Unformatted text preview: on et al. (10) used a 25-year record of the occurrence of
potato late blight in commercial fields to develop a discriminant function relating rain variables and outbreaks of potato late blight
in the state of Washington. Similarly, Hennessy et al. (8) employed discriminant analysis to determine how climatic factors
(rainfall and minimum and maximum air temperature) influence
severity of sorghum leaf blight in South Africa. Noe and Barker
(14) used canonical discriminant analysis to determine which
edaphic factors contributed the most in delineating three levels of
nematode densities (low, medium, and high). Chakraborty et al.
(2) characterized and classified pathogenic races of isolates of
Colletotrichum gloeosporioides based on disease severity on
Stylosanthes scabra, a tropical pasture legume. Workneh et al.
(20) defined classes of corky root severity in tomatoes using
discriminant analysis to ascertain the distinction among severity
classes based on a set of soil and plant variables.
