A significant negative effect of the
6Ag
i
(
6D
) chromosome from
Agropyron intermedium
on the resistance of spring bread wheat
Triticum aestivum
to preharvesting sprouting has been demonstrated in redgrain and white-grain recombinant inbred lines (F7–F10 and older) and in near isogenic lines. The resistance of various red-grain recombinant inbred lines carrying this chromosome to preharvesting sprouting has been shown to vary considerably, this presumably being due to the effects of genetic background. The mechanism of the negative effect of the
6Ag
i
(
6D
) chromosome from
Agropyron intermedium
on the resistance of bread wheat to preharvesting sprouting remains unknown.
