Technical Abstract: Postharvest yellowing (PHY), or stackburn, reduces the value of rice. The identification of a low PHY rice cultivar would be desirable for breeding purposes, as well as for understanding of the PHY phenomenon. A laboratory method was used to survey different cultivars of rice for their ability to undergo PHY. Milled rice was placed in test tubes, the rice was rinsed with water, then heated to 70C for four days. Color was measured with a colorimeter. Two different cultivars, Terunishiki and Akinishiki, have low levels of PHY, consistent across two growing seasons and could be valuable for further studies and as breeding material.
