F2 Rosette-Dwarf, Non-Purple Stem Fast Plants seed packet

F2 Rosette-Dwarf, Non-Purple Stem Variety

F2 Rosette-Dwarf, Non-Purple Stem

Phenotypes: standard & rosette forms and purple & non-purple stems
Genotypes are variable combinations from the cross: ROS/ros, anl/ANL x ROS/ros, anl/ANL

F2 Rosette-Dwarf, Non-Purple Stem stock is produced from a cross between parents from the F1 Rosette-Dwarf, Non-Purple Stem stock, meaning both parents were heterozygous for two genes (ROS/ros, anl/ANL x ROS/ros, anl/ANL). This F2 (second) generation Fast Plants population exhibits the Mendelian-predicted 9:3:3:1 ratio of form and stem color phenotypes (see front envelope image). Note that an F2 population sample size must typically be sufficiently large (>100 plants) to demonstrate the 9:3:3:1 theoretical phenotype probability.

Fast Plants need 24 hour light, continuous moisture, and soil-free potting mix
