Estimation of the introgression level in Populus nigra L. populations by means of isozyme gene markers

Popis výsledku v původním jazyce

Enzyme systems 6-PGD;LAP;GPI were tested in the progeny of a controlled crossing of Populus x canadensis x P. nigra with the object of distinguishing hybrids in a population of P. nigra. Segregation ratios of 1:1 for 6-PGD and LAP were determined among phenotypes corresponding to P. nigra (homozygote) and P. x canadensis (heterozygote). The segregation ratio for GPI was 3:1 in favour of the homozygote Experimental results proved that it is possible to identify hybrids of the P. x canadensis x P. nigra type from spontaneous populations of P. nigra. These results enabled analyses of three populations of P. nigra. In the generative progeny of the female trees of P. nigra no hybrids were ascertained. In a population of trees 10-18 years of age 9,7 % were hybrids with P. x canadense yet not differend from P. nigra morphologically.
