ABSTRACT:
Commercial hybrid wheat is produced by growing under a condition of, for example, not less than 14 hours day length (condition A) common wheat variety in which D.sup.2 -type cytoplasma from Aegilops species has been introduced until cytoplasmic male-sterility is induced, producing hybrid seeds by growing in alternating blocks with a pollinator parent with a good combining ability, maintaining the said male-sterile D.sup.2 -type alloplasmic lines by self pollination by growing under condition of, for example, less than 14 hours day length (condition B), and harvesting by growing the said hybrid under condition A or B.
