Genetics of allozymes in Populus deltoides Marsh., P. nigra L., and P. maximowiczii Henry.

Progenies of 12 controlled crosses of Populus deltoides Marsh. with P. deltoides, P. nigra L., and P. maximowiczii Henry were analyzed by means of starch gel electrophoresis to examine the inheritance of isozymes of 34 to 36 loci that code for 12 enzymes in the roots of P. deltoides, P. nigra and P. maximowiczii
