Abstract
SUMMARY: In two-way selection for growth rate in the fungusSchizophyllum communein two environments (20 °C and 30 °C) response for low growth rate was always greater than for high. This asymmetry was due to inbreeding depression combined with a greater selection differential associated with the low lines in the high temperature environment. Despite the high level of inbreeding applied, two low selection lines derived from the same source (parental isolate 2) showed no decrease in genetic variance during selection. This maintenance of genetic variance was associated with a decrease in stability of development relative to the corresponding high selection lines.Keywords
