In the white fl owering plants, for example, there were only light-green vegetative
organs, medium-sized and egg-shaped leaves, and erect bush form. The average plant
height was 105 cm, the number of the stems per plant is 10 pieces, and weight of the
seeds per plant is 22.1 g, weight of 1000 seeds was 7.3 g. Among other phenotypes,
blue fl owering and violet fl owering plants had the greatest variety of forms. As a re-
sult of the recombination of genes, they formed plants with green, dark-green and
violet-pigmented leaves small, medium, and large in size, ovate, lanceolate, and oval
in shape. As to the seed production, phenotypes with blue fl owering and violet fl ow-
ering with dark-green leaves were the best. They produced 62.6 and 62.7 g of seeds
per each plant. As a result of the evaluation in the nursery of the second-generation
hybrids, 82 plants with different manifestation of morphological and economically
useful traits have been found. In order to obtain constant variety samples of each type,
the best plants with white, lilac, light-blue, blue and violet fl owering having complex
of economically useful characteristics and properties were planted in isolated areas.
In isolation, as a result of self-pollination of each selected plant, they produced
full-grown, with high-sowing quality seeds, and should be noted that the seed ovary
in self-pollination was low, lot of beans were empty with no seeds, and the selected
qualitative seeds were used for further propagation of constant samples and their com-
parative evaluation in the selection process. To do this, seedlings were grown from the
seeds in the laboratory and they were planted in the fi elds. Each species was planted
individually with the nutritional space of 70 × 70 cm

. This has enabled us in the short
term to propagate them and get the required amount of the seeds.
The result of the further studies was the formation of constant variety samples
of
G. orientalis
with different combinations of morphological traits that have practi-
cal importance as standard variety samples for comparison of new varieties for their
identifi cation. Thus, by the color of fl owers and vegetative organs, we have isolated
and vegetatively propagated six standard variety samples (SEG) of different varieties.
Among them are SEG-1—white fl owers with light-green leaves and stems, SEG-2—
lilac fl owers with dark-green leaves and stems, SEG-3—with light-blue fl owers and
