Provided is a method for screening a population of plants for the presence
therein of individuals that show a reduced susceptibility to ethylene and
physiological disorders, in particular Russet Spotting and Yellowing, as
compared to a control plant, wherein a population of seeds is germinated
in darkness and in the presence of ethylene to obtain seedlings that,
when having a longer hypocotyl as compared to the original
ethylene-sensitive control under ethylene, are selected as plants showing
a reduced susceptibility to ethylene and physiological disorders, in
particular Russet Spotting or Yellowing. Also provided are plants thus
selected.
