A NEW MALE-STERILITY IN CHIVE (ALLIUM-SCHOENOPRASUM L)

In chive cv. 'Wilau' selected male sterile plants were characterized m olecularly and cytogenetically. A comparison with other male sterile t ypes of Allium schoenoprasum showed differences for microsporogenesis, the mt protein biosynthesis, and restriction enzyme analysis. The off spring in progenies of the male sterile types gives clear indications for a new male sterility. It is proposed to use the symbol (M) for its cytoplasm and W for the dominant restorer gene.
