The recessive mutant virescent26 was obtained by Neuffer and Beckett (MNL 61:50, 1987), who originally designated it as v-453A. They placed it on 2S since it was uncovered by TB-3La-2S(6270) but not by TB-3La.
Linkage tests with other 2S markers were made to map v26. The
source of our v26 stock was Coop. 89-582-1. Seedlings are strongly
yellowish-white, and green slowly from tip to base without becoming grainy.
Culms, leaf sheaths, and husks are whitish, although the MNL gene lists
and description in Mutants of Maize (Neuffer, Coe and Wessler, 1997) do
not mention this. Some variability in expression was noted among our progenies
for these traits at anthesis, however. Viability is normal and ears are
obtained if adjacent normal sibs are removed early. The F2 repulsion data
were as follows:

These data place v26 about 27 cM distal to gl2 and 12
cM distal to lg1, which is very near ws3. Because of this
location and the similarity of culm, sheath and husk phenotypes of v26
to ws3, we tested the two mutants for allelism. Surprisingly, the
ws3
stock obtained from the Maize Coop. also had virescent seedlings, although
this is not stated in the MNL gene lists or in Mutants of Maize. Crosses
between these two mutants proved them to be allelic. The symbol
ws3
has priority.
