Hagberg falling number (FN) is an important quality trait used for grain grading. The FN test can only be measured in the late stages of variety development when progeny are homogeneous. The FN is strongly influenced by environmental conditions during reproductive growth stages, including excess moisture, extreme temperature, and biotic stresses. Falling number, a procedure that indirectly characterizes germination enzyme activity in wheat grain by measuring the viscous behavior of a heated flour–water or meal–water mixture,. Fallic enables millers to influence the falling nr of their flour.
