During the eight-year research period, we determined the peculiarities and regularities
of morphological (length and diameter) and anatomical (stem thickness) features of oilseed radish
pods considering their location within the generative part of plants for different types of spatial
structure of the inflorescence generated in agrocenosises of different densities. We carried out the
analysis and statistical grouping of morphological features of oil radish pod in the full range of
possible technological options of pre-sowing construction of its agrocenosises, as well as within
the selected three zones (tiers) of inflorescence by the nature of variation and variability of
morphoparameters pod, namely, lower, middle and upper. We described in detail the stages of
pod formation (microstages ВВСН 69-87) considering features of its linear and radial growth,
peculiarities of formation of general internal anatomical structure with analysis of mathematical
and statistical regularities of changes in these parameters in accordance as per order of its
placement within an inflorescence (separately main axis and system of lateral branches). We
determined the optimum technological intervals for the construction of oilseed radish
agrocenosises, which ensure the combination of appropriate levels of morphometry formation of
its fruit elements with the predicted level of reproductive effort and seed productivity. We made
a general assessment of the peculiarities of formation of pod technological effectiveness in terms
of ease of threshing and possible losses of seeds depending on the complex of factors under study.
