ABSTRACT

The objective of the study was classification of the experimental stations of the Post-registration Variety Testing (PDO) Programme in Lower Silesia into groups with notable similarity in the variation of the winter wheat cultivars performance. The analysis covered yields of the winter wheat obtained in seven PDO experiments in the years 2009–2011 carried out at high level of cultivation, comprising full chemical protection against pests and fungal diseases, application of an anti-lodging agent, and supplementary foliar nutrition. The research was based on the results of grain yields of 11 winter wheat cultivars; the experiments set up in the two-factor strip-plot design. The results obtained permitted identification within the experimental stations analyzed of three groups of localities differing significantly in the yield variability of the wheat cultivars studied. The first group includes Tomaszów and Naroczycze. The second group, composed of a single element, is made up by the experimental station of Pawłowice, which is characterized by lack of correlation with the other localities. The third group includes Zybiszów, Kobierzyce, Kondratowice and Tarnów. The significant changes taking place in the soil-climate environment indicate that micro-regionalization of the winter wheat cultivars under the diverse conditions of certain areas in the provinces of South Poland may contribute to an increase in yields of this cereal crop.

Key words: variability, factor analysis, matrix, correlation coefficients.
