Tobacco mosaic resistance.<p>

Soost, R. K.<p>

In TGC 8:35 my report on this resistance indicated a possible isolation of a
homozygous resistant line not containing the associated recessive virescent
mutant nv.  However, additional plantings have definitely demonstrated that
this line is segregating for nv as well as for tobacco mosaic resistance.
Letters from C. D. Clayberg and Arnulf R. Persson indicate that in all of
their plantings of material of this same resistant source, nv plants have been
present in all families with resistant, normal plants.  Thus the information
to date indicates either close linkage of nv with tobacco mosaic resistance or
pleiotropic effects of one gene.<p>
