1. Opaque grains caused by low amylose content in endosperm, similar to waxy (glutinous) rice phenotype. The top row is brown rice, the middle row is milled rice, and the bottom row is reaction to I2-KI solution. From left to right, the first is normal, the second is du-1, the third is du-2, the forth is du-3, the fifth is du-4, the sixth is du-5.
