The genetic and cytogenetic analyses of the spring common wheat line L-592
with a waxless spike, obtained by crossing T. aestivum (cv. Rodina) x Aegil
ops speltoides (k-1316), were conducted. A new inhibitor gene of the develo
pment of waxy bloom on spikes, designated W4(I) was identified A possible l
ocation of this gene on chromosome 7S of Ae. speltoides was suggested.
