Comment	This allele is currently used to denote a large deletion of undetermined size that involves Pina-D1, Pinb-D1 and Gsp-D1 (Tranquilli et al. 2002) he deletion of both puroindolines is associated with harder kernel texture than other known puroindoline hardness alleles (Tranquilli et al. 2002; Ikeda et al. 2005; Tanaka et al. 2007) (Curator note, VCB Jul2021) Ths is a partial list of germplasm.
