test the power of the three species-specific RAPD primers and their corresponding SCAR primers, the six primers were
used to amplify a large seed lot composed of 50 individuals of each species. The percentage of seed-specific fragments
amplified by the SCAR primer SCB1/SCB2 was 92% in the seed lot of Larix gmelinii and 90% in the seed lot of L. olgensis. The
species-specific fragment amplified by the SCN1/SCN2 SCAR primer was found in 86% of the L. principis-rupprechtii seed
samples and that amplified by the SCX1/SCX2 SCAR primer was present in 88% of the Larix gmelinii seed samples. The speciesspecific
fragments amplified by the three SCAR primers were found in higher percentages of the populations than those
obtained with the RAPD primers
