Phenotype: stems lack all purple
Genotype: anl/anl

Non-Purple Stem, Hairless is a true-breeding Fast Plants stock that is homozygous recessive for a gene that inhibits expression of the purple pigment, anthocyanin. This stock shows no purple coloration in stem, leaves, or any other plant parts. Additionally, this stock has few to no hairs (known as trichomes) on stems or leaves.

Investigations

• Inheritance studies involving purple pigment (anthocyanin) production and expression in crosses with Purple Stem variety
• Investigating the inheritance of leaf hairs (trichomes)
