We have performed an analysis of the current state of
rice seed production in the Krasnodar region. It is
shown that over the last 10 years in Kuban a full
variety changing took place, which was caused by
State support of rice seed production on the federal
and the regional levels. Agricultural producers of the
Krasnodar region have completely stopped cultivation
of medium-ripening rice of Liman variety, increasing
acreage of new varieties such as Victoriya, Sonet,
Diamant, etc. which allowed to increase crop yield
from 47,1 centner/ha in 2006 to 63,0 centners/ha in
2015 and to improve the quality of commercial grain,
decreasing the content of red-grain forms average in
the Krasnodar region from 20,5% in 2006 to 1,8% in
2015. Legal basis of realization of state agrarian
policy in the field of seed production of agricultural
crops, including rice is reviewed, recent changes in
the legislation of the Krasnodar region concerning
seed production of agricultural crops are shown, as it
was reflected in the Law of the Krasnodar region â„–
3062-KZ dated 28.11.2014 "On the regulation of
certain relations in the field of seed production in the
Krasnodar region". Areas contributing to the
development of the rice seed production in the Kuban
region are identified for further conducting of variety
changing, introducing new high-yielding varieties into
production as well as varieties of special purpose for
import substitution
The article reviews four variants of laying nurseries of
primary branches of seed production of long-grained
rice varieties of the Kuban breeding taking into
account their biological features, plots area ranges
from 0,7 m2
to 1,1 m2
, seeding rate for one family –
from 100 pcs./m 2 to 170 pcs./m2 . We have studied
traits of long-grained rice varieties of the Kuban
breeding - Ivushka, Avstral, Kurazh, affecting the
yield and quality of seeds: yield, multiplication factor
and fractional composition of seeds depending on
laying multiplication nursery of first year progeny.
The differences between varieties by the type of
tillering, vigor, germination of seeds depending on
planting system are shown. Optimal way for laying
seed nurseries is found: for long-grained varieties with
medium tillering (Kurazh type) – row length – 3,3 m
and seeding rate – 120 caryopses/m2
; for those with
intensive tillering (Ivushka type) – row length – 3,8 m
and seeding rate - 120 caryopses/m2
. This will allow
using mechanical method of sowing using selective
cassette seeding-machine in the primary seed
production, reducing cost of seed production and
increasing efficiency of labor, increasing volume of
seed production of long-grained rice varieties in short
terms and accelerating their implementation in the
Kuban region for import substitution
An analysis of the state of contamination of rice crops
with red-grained forms was carried out, as well as
impurity was found both in the seed material and in
the soil. It was shown that there is a need to switch to
non-weeding seed growing technology when
conducting elite and reproductive seed production.
Various variants of soil cultivation in combating the
red rice forms are considered, both in the main and in
the pre-sowing treatment. It has been found that after
harvesting rice on heavily foul areas, it is better to
burn straw, and not to carry out autumn tillage of the
soil, the seeds of red-grained forms die mostly when
wintering on the soil surface. The most effective
method of soil cultivation for controlling of red rice
forms in seed crops has been identified, in which the
yield is increased, and the contamination of crops and
the resulting rice grain is significantly reduced. The
work carried out will allow reducing manual labor
costs in the production of seeds, improving their
quality and assortment, speed up variety changing and
variety updating
