Abstract: A novel antibody that can be used as an anti-tumor agent and an anti-tumor agent that comprises, as an active ingredient, a molecule containing such an antibody.

Abstract: The present invention relates to the production of hybrid wheat and triticale plants and seeds via the employment of genetically-controlled cytoplasmic male sterility (CMS) and genetically-controlled fertility restoration. The genetically-controlled cytoplasmic sterility mechanism according to the present system and method utilizes genes conferring CMS in the presence of Aegilops squarrosa cytoplasm, and for restoring fertility to wheat and triticale plants having Aegilops species cytoplasm. The invention also relates to the use of specific, induced mutant sources of tolerance to herbicides for destroying the seed producing ability of the male fertility restorer parent after pollination has completed, to achieve essentially 100% hybrid seed reproduction from a mixture of a CMS male sterile line and a pollen fertility restorer line.

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.
