The analysis of the character of the distribution at the interspecific level showed
a significant positive excess in Vigna angularis by the number of seeds from the plant
(Ex = 6,54; p≤0,05) and the number of beans per plant (Ex = 2,01; p≤0,05 ) and in
Vigna unduiculata for seed yield (Ex = 5.24; p≤0.05) (Table 7). Consequently, the
plants in the populations of these species of vigna are often characterized by average
values of the indicated signs.
The presence of a certain level of asymmetry and excess in the studied samples of
vigna show the peculiarities of the response of the relevant genotypes to the action of
the abiotic and biotic factors of the environment and can serve as a criterion for the
adaptability of the species as a whole and certain collections in particular.

The general assessment of the polymorphism of the collection samples of
vigna by morphological and economic characteristics.
Fery et al. [9] emphasize the
necessity of attracting various varieties of genetic material into vigna breeding as this
will contribute to the expansion of the cultural production and help meet the needs of
the national economy in varieties of various intended uses.
It is important to look for
forms to create idiotypes that meets the requirements of a particular region.
The analysis of the phenotypic diversity of the vigna collection allowed to
establish a significant variability of the investigated plant material for the
morphological and economic-valuable features studied.
