Germplasm Phenotype:

• psy2l  — Plants are dwarf, and extremely slow growing. They grow into small bushy plants producing many flowering stems with poor silique development and very few seeds per plant. Plants easily developed purple colored leaves with high anthocyanin content. Defects in pollen germination and dehiscence, root meristem shape, seed germination.
