Genetical analyses were conducted to find linkages and the locus of the gene calf on the Pisum chromosome map. The recessive, pleiotropic gene calf (enlarged and undulated leaflets, stipules, flowers and pods, plant sterile), artificially induced (the initial line-Large Podded G-20, the mutagene-DES and NMU) was described by Sharma in 1975. An identical mutant gene at the same locus was isolated in our research (the initial line - cv. Pegro, the mutagene - fast neutrons). 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 gene order: Orp - Calf - K - Pgm-p - Fum. This is in agreement with the current Pisum linkage map.
