Hereditary dwarfism in yellow lupin (Lupinus luteus L)

Tadeusz Kazimierski, Ewa M. Kazimierska

Abstract


A dwarf plant was found in the F4 generation of a hybrid between two yellow lupin subspecies. Genetic analysis demonstrated that the dwarf grwoth is conditioned by one recessive factor which was named nanus. This factor acts pleiotroipically since it reduces the height, changes the morphological structure and some anatomical traits and reduces fertility in the dwarf plants. It is believed that in the chromosome with translocation a gene block arose in the F4, plant. These genes acting as a compact system cause dwarfism, changes in the anatomical structure and reduce fertility.
