Abstract
Introduction of new varieties to the cultivation is associated with the risk of failure in the production which increases with decreasing knowledge of their response to different environmental conditions and crop management factors. Thus, the implementation of each variety does not stop at the stage of preliminary tests and its registration, but next to the reproduction of the seed, it also includes an assessment of the economic value of variety in multiple series of post-registration trials. A steady supply to agriculture of newly registered varieties requires from the post-registration experimental variety testing, the efficient and reliable verification of the economic value of tested varieties. These field experiments allow to significantly reduce the risk of introducing the cultivation of varieties unsuitable for agriculture, i.e. those which do not provide high production and economic effects in different or only selected (specific) environmental conditions and systems of crops and agricultural techniques. Data from these series of experiments require the use of specialized and complementary statistical methodology. In this work, an overview of a series of varietal and agrotechnical experiments is presented and the statistical methodology described.
