The highest level of diversity in the total sample of the collection samples of vigna
is detected on the basis of a mass of 1000 seeds (H’= 0.98, H’max = 1.10, E = 0.89)
(Table 8).

Significant variability was noted by the type of pigmentation of the stem (H’=
1.17, H’max = 1.79, E = 0.66), colour of the bean, bean pigmentation and seed yield
(respectively, H’ = 1.17; 0 , 75, 0.70 and 0.7, H’max = 1.79 and 1.10, E = 0.66, 0.68,
0.64 and 0.89).
The minimum level of polymorphism is established on the basis of the
colour of the leaves (H’ = 0,20, H’max = 2,08, E = 0,09) (Table 8).
Also, some interspecific features of the level of genetic diversity of vigna have
been noted for morphological and economic characteristics (Fig. 1).
Among the species of vigna involved in the study, the maximum level of
variability was characterized by the species Vigna unduiculata (mean value H’ = 0.67,
E = 0.56). The lowest level of diversity was noted for specimens of the species Vigna
umbellta (mean value H’ = 0.40, E = 0.34).
The species of Vigna aconitifolia, Vigna radiata and Vigna angularis were
characterized by mean values of the indexes of the Shannon variety and Piel equation
(H’ = 0.51, 0.51 and 0.44, E = 0.43, 0.43 and 0.37).
The assessment of the diversity of vigna at the individual level made it possible
to establish that the varieties represented in the collection were less heterogeneous than
the local populations (Table 9).
Among the studied varieties, the maximum level of phenotypic polymorphism
was established for samples of Hybrid 7 (UD1000044), Vegetable Soy (UKR001:
00048) and Shan-li (UD1000005) (respectively, H’1 = 0.76, H’2 = 0.64, H’3 = 0.62;
