Narrative
The extreme dwarf mutant (GSOR 23) was observed in 5 out of 11 plants in a single M2 row in 2003. In subsequent tests, the extreme dwarf plants averaged 24 cm tall compared to 80 cm for the homozygous tall sibs. In a sample of 100 or more grains, brown rice length, width and kernel weight from the mutant plants were 6 mm, 2.1 mm, and 16 mg, compared to 6.8 mm, 2.4 mm, and 22 mg for the parent genotype. Seeds of extreme dwarf plants were composited to form a genetic stock that is pure breeding for the extreme dwarf mutant phenotype.

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

Pedigree
Description:
Selected from a gamma-ray mutagenized indica (300 Gy) M2 population grown at Stuttgart in 2003. The mutagenized line was a sib to the previously released germplasm line indica-9 (PI 634583) derived from the cross ZHE733/IR64.
