    Milky Queen

    ミルキークイーン

    A low-amylose mutant of Koshihikari, selected after chemical mutagenesis and registered in 1995. Its amylose (9.1–12.2 %) is about 60 % of Koshihikari's, giving a dull, milky grain and a soft, sticky cooked rice.

    A pale polished rice grain, illustrated for Milky Queen.

    Koshihikari with less amylose

    Breeders treated Koshihikari with the chemical mutagen N-methyl-N-nitrosourea and selected low-amylose plants from the progeny. A line from the seventh generation, Kanto 168, was tested with 45 prefectural stations from 1992 to 1994 and registered as Paddy Rice Norin 332, Milky Queen, in 1995.

    Its amylose ranged from 9.1 to 12.2 % (mean 10.1 %), against a mean of 17.5 % for Koshihikari. The endosperm looks dull, between waxy glutinous rice and ordinary rice. In the field it behaves much like Koshihikari, including its weakness to lodging and blast; its brown-rice grains are slightly smaller (19.8 mg against 20.5 mg each).
