Delayed occurrence of mutant resembling wiry erroneously reported.<p>

Lesley, J. W.<p>

The absence of a Wiry-like mutant in R2 from X-ray-treated seeds followed by
its occurrence in R3 in nearly the expected proportion led to an erroneous
conclusion (TGC.4.1954: 14).  An additional sowing of the same R2 consisted of
23 normal and 3 wiry-like.  Reference to previous data shows that the ratio of
normal to wiry in F2 ranged from 271:87 to 153:3. The occurrence of the mutant
was only delayed because too few R2 seeds were planted! Pollen of dd\m\cluh+
on the mutant unexpectedly produced two viable seeds from which two fertile
d^+^d\m\^+^l^+^h^+ plants developed.  Despite this slight egg fertility and
the more syncarpous ovary, it seems probable that this mutant is the same as
the wiry previously described.  Another mutant again occurred in the R2, in
addition to wiry, which was semi-determinate, later -ripening., and had
narrower more purple leaves than normal sibs of First Early. It may of course
be due to an independent change caused by the X-rays.<p>
