Narrative
Seeds of Drew were treated with 250 Gy of gamma rays in 1999. In the M2 generation, 8 random panicles were taken from each panicle row. In one row 7 plants with normal kernels and 1 plant with giant embryo kernels were observed. The mutant plant subsequently was crossed back to the parent Drew. Kernels on the F1 plants, grown in the greenhouse in 2004 appeared normal, while the F2 plants, grown in the field in 2005, segregated 135 normal:60 giant embryo, a satisfactory fit (0.05 less than P less than 0.10) to a single recessive gene ratio. Thousand brown rice kernel weight of the mutant was 13.75 grams compared 15.84 grams of the parent, Drew, a 13% decrease. The brown rice oil content of the mutant was 3.69%, compared to 2.70% for the parent.

Comment:
some seed lots of domesticated rice may contain contaminants of a noxious weed hybrid-form that are not distinguishable by seed visualization, which is responsible for the rice-growing state's noxious-weed seed regulations indicated below
