F1 Rosette-Dwarf, Non-Purple Stem

Phenotype: standard form and purple stems
Genotype: ROS/ros, anl/ANL

F1 Rosette-Dwarf, Non-Purple Stem is Fast Plants stock that is heterozygous for two genes, produced from a controlled dihybrid cross between standard form, Non-Purple Stem and Rosette-Dwarf, Purple-Stem parents (ROS/ROS, anl/anl x ros/ros, ANL/ANL). In this F1 (first) generation population, only the dominant phenotypes are expressed, so all are standard form with purple stems. Note: there may be occasional plants in this seed stock that have non-purple stems due to mutation or rare crossbreeding between sibling-plants. Should this occur, remove any non-purple seedlings when they are most noticeable at 5-7 days old.
