Micro Sedimentation Test for Wheat

VIEW METHOD

Objective
This method is similar to Method 56-61A in principle, but it uses a 10-fold reduction in sample size. It is based on measuring volume of sediment that results from treating a water-flour mixture with lactic acid. The essential differences are: 1) a larger proportionate amount of reagent to overcome "ceiling effect" (see Note); 2) reduction in mill roll spacing to increase flour yield; and 3) adjustment of wheat moisture content to approximately 13% to avoid variations due to moisture. It is especially used as a screen method in early-generation selections in wheat breeding.
