Thus, standard variety samples are characterized by a certain set of quantitative
and qualitative traits, making it possible for the identifi cation of varieties [12, 13].
Their further development will continue. The established standard variety samples
of
G. orientalis
have been used by us to develop a methodology for establishing the
criteria of novelty, DUS of the test varieties for patentability.
The project of private methodology to test
G. orientalis
for DUS was developed at
the Department of Breeding and Genetics at the Belarussian State Agricultural Acade-
my and was tested on standard variety samples at the GVTS “Gorki variety testing sta-
tion” and in 2013 was transferred to the state institution “State Inspection for Testing
and Protection of Plant Varieties” for implementation into practice of state testing va-
rieties of
G. orientalis
for identifi cation and patentability. In other countries, members
of the International Union of States on Protection of New Varieties up to date, there is
a lack of standard variety samples of
G. orientalis
and methodology determining the
criteria of novelty, DUS.
It allowed Belarus to contribute to the solution of this problem.
26.2 CONCLUSIONS
• The laws of manifestation of genetic variation in the hybrid generations of le-
gumes can be effectively used in breeding
G. orientalis
to accelerate the breed-
ing process and predict in hybrid populations planned genotypes differing in
morphological and economically valuable traits.
• Effective source for obtaining genotypic variation in
G. orientalis
can be mutant
white flowering plants obtained from perennial crops of the blue flowering pop-
ulation of the variety Nesterka as well as artificial hybrid populations derived
from the crosses between selected parental forms.
• The law of homologous series in hereditary variation and found in it parallelism
of the inheritance of traits in legumes served as a theoretical basis for acceler-
ating morphogenetic process in
G. orientalis
to expand its range of genotypic
variation.
• As a result of the selection work done by us in a short time constant variety
samples of
G. orientalis
were created with genotypic variability characterized
by differently colored flowers and vegetative organs. Among them are: SEG-
1—white flowers with light-green leaves and stems, SEG-2—lilac flowers with
dark-green leaves and stems, SEG-3—with light-blue flowers and dark-green
leaves and stems, SEG-4—with blue flowers and dark-green leaves and stems,
SEG-5—with violet flowers and purple pigmented leaves and stems, and SEG-
6—with cream-colored flowers and dark-green leaves and stems.
• Variety sample SEG-5 with violet flowers had the best indicators of seed pro-
duction. One plant produced 75.0 g of high-quality seeds.
• Variety sample SEG-1 with white flowers and light-green leaves and stems was
the best as to crude protein content. This parameter compared to the other types
was higher by 2.1-4.5 percent and made up 27.7 percent.
• The established variety samples of
G. orientalis
have been used as standard
variety samples for developing a project of private methodology on variety test-
ing for DUS.
