Narrative
DR1 was induced in the tall Arkansas rice cultivar, 'Drew', in order to quickly obtain semidwarfism in adapted germplasm. This mutant, which at 97 cm is 22% shorter than its parent provides a breeding source of semidwarfism, nonallelic to the worldwide semidwarfing gene sd1, in tropical japonica germplasm adapted to the southern US and similar climactic areas. This mutant provides an alternative semidwarfing source should genetic vulnerability problems arise from widespread use of sd1.

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
