Description

Two sets of durum samples were used to determine kernel characteristics and milling properties of durum genotypes grown in North Dakota, USA. Kernels were characterized for kernel size (length, width, and thickness), germ size (length and width), and shape (kernel width/kernel length, volume, sphericity, germ width/germ length, germ length/kernel length, and germ width/kernel width). Kernels were also characterized for their test weight, kernel weight, vitreousness and hardness. Milling properties evaluated were break release, milling rate, total extraction, semolina extraction, and semolina quality. All kernel characteristics and milling properties varied with genotype and growing location. First break release and milling rate were influenced by kernel shape and size. Larger, wider, and rounder kernels tended to result in better milling performance in the first break. Kernel hardness and vitreousness were strongly correlated and both were positively correlated to semolina extraction but not total extraction.
