The Use of Pollen Isoenzymes as an AId to the Breeding of Field Beans (Vicia Faba L.)

s ummary Non‐specific esterase and glutamate‐oxaloacetate transaminase isoenzymes, extracted from pollen and separated by electrophoresis on acrylamide gel, have been used to identify inbred lines and to measure crossing between them. Isoenzyme patterns were genotype‐specific and were not affected by a range of environmental variables or by prolonged storage of pollen at low temperature.
