The integration of plant breeding and plant transformation is needed because we have to create a homozygous genotype of great agronomic value by conventional breeding before the application of genetic technology with which we modify it by using a gene or genome sequence. The aim of integrated plant breeding is to trigger such advantegous changes by genetic technology which can not be achieved via conventional breeding or just with considerably weaker efficacy. By transformation, the plant’s agronomic performance, the efficiency and security of its production will improve and it will enable more versatile uses of the plant. Genetic technology is one sequence of a new plant variety’ breeding. To create a transgenic variety, the isolation of a gene or a sequence of a gene from the donor genome for tranformation, a homozygous plant or target genome that is suitable for transformation and is created via conventional breeding methods, an effective transformation technique and the establishment of the new variety from the transformed, fertile plant are needed. The transgenic plant should be made suitable for establishing a variety by conventional breeding so that it could be produced securely, its growing could contribute to the development of modern, sustainable agriculture, its seed could be produced profitably, it could meet the reqiurements of DUS and that the changes indicated by the transgene could provide such economic advantages compared to the original variety, which have real commercial value.
