The analysis of the collection after the vegetation period and the individual phases
of the development allowed to establish the variation of these characteristics on the
intraspecies and interspecies levels.
The results of the analysis are presented in Tables
2 and 3.
According to the duration of the growing season, three groups of ripeness are
singed out [6]: early ripening – up to 70 days, mid-ripening – 71-90 days, late ripening
– more than 90 days.
The collection studied by us was represented by genotypes of
three groups of ripeness: early ripening, mid-ripening and late- ripening specimens.

The shortest growing period, the average duration of which was 60 days, was in
Vigna aconitifolia.
During the years of research this species also showed the largest
variation in the length of the growing season (Cv = 4.5%) which varied from 54 days
in the sample UD1000033, to 65 days in populations UD1000019.
The longest growing period was characterized by the species Vigna unduiculata
(113 days).
At the same time, this species showed the greatest constancy of this feature
(Cv = 1,4%) compared with other species.
During the studies the length of the growing
season in specimens of the species Vigna unduiculata varied from 108 days in the
population UKR001:00048 to 117 days in the population UD1000045.
According to the results of the evaluation of the variability of the individual
phases of development the following is established.
The longest studied samples were
the phase of a massive shoots-flowering, the duration of which lasted 46 days on
average over the years of research and ranged from 28 (sample UD1000033, Vigna
aconitifolia) to 62 days (sample UD1000052, Vigna umbellta).
The level of variability
of this phase was maximum (Cv = 13.0%) among the evolutionary phases of vigna and
