Atrazine Resistant Standard 1-156

Sold in packs of 100 seeds.

Plants of stock 1-156 grow normally under exposure of leaves or roots to concentrations of Atrazine herbicide that rapidly kills other rapid-cycling Brassica rapa lacking the (tzr) gene.  Tzr is conferred through a mutation in the chloroplastic genome and transmitted uniparentally through the cytoplasm of the egg.  

Plants of 1-156 appear clear green with no purple pigment (anthocyanin) on stems, leaves, or other plant parts including the seed coat.
