The only statistically significant linkage is shown with T9-10b on 10S. This suggests that Les*-A7145 is on the short arm of chromosome 10 left of the breakpoint of T9-10(8630).

This mutant originated as a spontaneous dominant necrotic mutant found by Dr. Jack Beckett (his number was 9469C-3). It has been designated Les*-A7145 in our cultures because the necrosis appears first as leaf lesions which enlarge and coalesce to form necrotic streaks.
