The recessive, pleiotropic gene calf, artificially induced was described by Sharma in 1975. An identical mutant gene at the same locus was isolated in this research. Two lines were included in the Pisum gene bank - the type line for the gene calf - Wt 15873 and the representative line - Wt 16024. In linkage studies the representative line was crossed with tester lines bearing gene markers. Analyses of dihybrid segregation in F2 generations revealed linkages of the gene calf with chromosome 2 markers. Two isozymic markers helped to reveal the calf locus on chromosome 2 with the following order: Orp - Calf - K Pgm-p Fum. This is agriment with the current Pisum linkage map
