This is a description sheet (with illustration) for the standard rapid cycling ideotype (RCI) or ideal form for the anthocyaninless, or non-purple stem phenotype. In the anthocyaninless line, a recessive gene blocks the expression of purple, red, or pink pigment, also selected for few or no hairs. Plants lack any purple anthocyanin pigment, anl, however the genetic background of the stock is for high expression of purple anthocyanin, Pan (7), a quantitative trait. None or very few hairs on any plant part, Hir(1), a quantitative trait. Most plants, >80%, are male fertile, MST2/- . A few are male sterile, mst2.
