Abstract

This paper reports on the production of intergeneric somatic hybrid plants between two sexually incompatible legume species. Medicago sativa (alfalfa, lucerne) leaf protoplasts were inactivated by lethal doses of iodoacetamide. Onobrychis viciifolia (sainfoin) suspension-cell protoplasts were gamma-irradiated at lethal doses. Following electrofusion under optimized conditions about 50,000 viable heterokaryons were produced in each test. The fusion products were cultured with the help of alfalfa nurse protoplasts. Functional complementation permitted only the heterokaryons to survive. A total of 706 putative heterokaryon-derived plantlets were regenerated and 570 survived transplantation to s..
