Instructions and tips for growing rapid-cycling brassica rapa variety “fpsc” brassica rapa fastplants sc (fpsc) is a plant variety specifically bred for educational use in classrooms and laboratories it is outwardly similar in gross phenotype and growth habit to the famous wisconsin fast plants (wfp) variety of rapid-cycling. Rapid-cycling brassicas, originally developed for plant breeding research, promise to be of value in school and college teaching within the family cruciferae, they are members of the same genus and species as the crop brassicas of great economic importance the crop brassicas are briefly reviewed as.

Paul williams, professor emeritus, department of plant pathology, uw-madison, describes the evolution of rapid cycling brassicas (scientific name: brassica rapa) which have been used for research and education for over 30 years at the university of wisconsin–madison these plants require little more.
A method using film pots (adapted from the traditional 4-pot technique), suitable for primary aged children, and useful to illustrate the whole life cycle in a short space of time and with plants that are small enough to keep in the classroom. Over the past 25 years, rapid-cycling brassica(rcbr) stocks developed from six species have become important model organisms for research and education researchers and educators turn to rcbr lines.

Wisconsin fast plants, rapid-cycling brassicas, are part of a large family of plants called crucifers (latin = cruciferae) crucifers are easily distinguished by the characteristic shape of their flowers—four petals in the shape of a cross or crucifix a section, or genus, of the crucifer family is the genus brassica brassicas have. We have developed experiments and materials to model human genetics using rapid cycling brassica rapa, also known as fast plants because of their self- incompatibility for pollination and the genetic diversity within strains, b rapa can serve as a relevant model for human genetics in teaching laboratory experiments.
