From 1998 to 2004, bulked populations were grown in Pembroke and plants were selected for a similar phenotype to the parental line. In each generation, seed was hand rouged and screened for a uniform black seed color. From 2005 to 2008, small scale field increases were grown and each generation was assessed for morphological stability and uniformity as part of the mass selection criteria during the vegetative, reproductive and seed phases.
