Plaza Durum

Plaza durum was released by the North Dakota Agricultural Experiment Station in 1999.  Plaza was selected from a cross between Plenty and an NDSU experimental line.

Plaza is a semi-dwarf with good resistance to lodging. It has high yield potential compared to other cultivars.  Plaza is particularly well suited for production under high yield conditions such as irrigation and high fertility. It is later maturing than most durum cultivars with test weight similar to Monroe and Munich but less than Ben and Maier.  Plaza has demonstrated better resistance to Fusarium head blight (scab) than Belzer and Rugby but its resistance to tan spot and septoria is somewhat less than other currently grown durum cultivars.

Plaza will be protected under Plant Variety Protection (PVP) with Title V restrictions.  It can be sold only as a class of certified seed.
