Aluminum limits wheat ( Triticum aestivum L.) yields on acid soils. An aluminum‐tolerant, N‐genome Triticum species was used to produce amphiploids, which were tested lor tolerance to 0.44 mM aluminum in solution, to assess the possibility of transferring tolerance to bread wheat. Two types of amphiploids, having the N‐genomc (Triticum uniaristatum) in common, were produced by treating three different Triticum ventricosum (DDNN) × Triticum turgidum (AABB) hybrids and a single Triticum ventricosun × Triticum timopheevii (AABB) hybrid with colchicine. It would appear that the N‐genome amphiploids can be utilized to transfer tolerance to aluminum to cultivated Triticum species and to study the genetics of tolerance in the N genome.
