Rezumat

The efficiency of application of different techniques to monitor the biologic purity of initial material designed for the
amelioration ensures the success of breeding programs. This means allow to estimate both, the homogeneity of inbred
lines and the polymorphism of in frame of populations. Field tests are much easier and exact, but are time consuming,
whereas laboratory tests provide fast results obtaining and reduce the expences for plant breeding programs. The utilization
of different existant methods are determined by the budget, developed by the breeders, for the analyses and by the level
of technical equipping of the laboratories. The most used method is based on the utilisation of storage protein electrophoretic
spectra, being relative cheap and sufficiently exact.
