| Abstract | Disease screening of varieties in the
selection program is an important
part of the decision-making process
for advancement of clones through
the program and release of new
varieties to industry. For many years,
disease ratings were given on a 1-to-9 scale based on the recommended
International Society of Sugarcane
Technologists method for assigning
disease resistance ratings. This 1-to-9 scale can be further categorised as
Resistant (1-3), Intermediate (4-6)
and susceptible (7-9). However, this
system didn’t take into account the
precision of the rating for any given
clone or variety. |
