Form Diversity of Erysimum cheiranthoides L. in cultivated populations



The phenopool of natural populations is realized in the cultivated populations of Erysimum cheiranthoides L. Four morphological forms are distinguished: acro-, meso-, basiton and non-branching. The frequency of form occurrence varies in the populations of different years. The acroton form in the populations turned out to be the most stable one. With respect to the key features, the individuals of non-branching form turned out to be the most deviated from the typical acroton form. It was established on the basis of the analysis of correlation matrices and the construction of correlation pleiads that the longer does the cultivated population exist, the closer links are elaborated between the productive indices of the species.
