CURRENT STATE AND PROSPECTS OF RICE SEED PRODUCTION IN THE KRASNODAR REGION

abstract 1211607019 issue 121 pp. 459 – 474 30.09.2016 ru 1124
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 № 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

FEATURES OF LAYING SEED NURSERIES OF LONG-GRAINED RICE VARIETIES FOR INCREASING VOLUMES OF SEEDS PRODUCED IN THE RUSSIAN FEDERATION

abstract 1191605007 issue 119 pp. 117 – 133 31.05.2016 ru 511
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

ISSUE OF DEVELOPMENT OF NONWEEDING TECHNOLOGY OF GROWING RICE SEEDS

abstract 1341710058 issue 134 pp. 733 – 742 29.12.2017 ru 216
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
