Introgression in black poplar (Populus nigra L. ssp. nigra) and its transmission
: Introgression was studied in the offspring of P. nigra and P. × canadensis female trees using 3 enzymatic patterns (6-PGD, LAP and GPI). Our investigations were aimed at the offspring from open pollination and controlled pollination by the pollen mixture from 3 clones of P. nigra and 3 clones of P...

| Abstract | : Introgression was studied in the offspring of P. nigra and P. × canadensis female trees using 3 enzymatic patterns (6-PGD, LAP and GPI). Our investigations were aimed at the offspring from open pollination and controlled pollination by the pollen mixture from 3 clones of P. nigra and 3 clones of P. × canadensis. The rate of introgression in P. nigra offspring from open pollination was 0.67%. Introgression in 3 offsprings of P. nigra from controlled pollination was 7.14%. In P. × canadensis the heterozygous: homozygous phenotype ratio in 2 offsprings from open pollination was 1:1; it documents prevailing fertilization by P. nigra pollen. After fertilization by the pollen mixture this segregation ratio was 1:1 (6-PGD; GPI) or 3:1 (LAP). The offspring of P. × canadensis maternal components are assumed to have a major share in introgression. |
