- Abstract
- Rapid, accurate and non-subjective grain tests help growers and processors agree on a fair price and ensure that the grain is used for the most appropriate purpose. Common tests include protein, moisture, test (hectolitre) weight, screenings and dockages for pests, disease and foreign matter (Vicgrain, 2000). Each test contributes to a more comprehensive assessment of the grain. The tests assist breeders when selecting promising new cultivars. Plant breeders and maltsters also use the thousand kernel weight (TKW) test, which provides additional information on seed morphology. The test indicates the average kernel weight, with the units expressed as grams per thousand seeds. TKWs are valuable to maltsters and millers as high TKW kernels are plumper, malt and/or mill more evenly and have a higher proportion of endosperm than small kernels. The high TKW grains also produce more attractive malt (Stuart, 1998). TKWs assist breeders in selecting large kernel cultivars and permit growers to calculate their optimum sowing rates (Schwarz and Horsley, 1995).; E1
