The article describes the advantages of seed encapsulation over other types of pre-sowing treatment. The essence of the method and the technological process of making dragees are revealed. Modern technology of production of vegetable crops provides for a high yield with high quality products. Increasing the yield of table root crops is possible through the use of new high-yielding varieties and hybrids, and reduce the non-standard part of the crop. The use of encapsulation in pre-sowing seed treatment in the cultivation of table carrots and table beets, in comparison with traditional methods of seed treatment, provides better retention of drugs on the surface and give a more positive effect on the intensive growth and development of plants of table carrots and beets, which reduces the direct costs of additional processing of crops and reduce the pesticide load on the crop.

Keywords: seeds, seed encapsulation, resource-saving technologies, seed pelleting, advantages of encapsulation, capsule manufacturing process.

The studies were conducted in 2016–2018 in the laboratory of genetics, breeding and biotechnology of vegetable crops of the RSAU – MTAA. The aim of the research is to assess the efficiency of known molecular markers orfA501 и 5» cob to genotype a type of onion (Allium cepa L.) male sterility inducing cytoplasm’s, CMS- (S) and CMS- (T) and normal (N) cytoplasm, to genotype restorer fertility and maintainer sterility alleles Ms/ms of a nuclear gene, marker of onion downy mildew resistance gene. The use of these two marker systems (orfA501 и 5» cob) confirmed the type of cytoplasm of all screened male sterility onion plants. Six onion accessions had CMS-S type of cytoplasm, four accessions – CMS-T and two accessions had normal N-cytoplasm. The efficiency of recommended DNA-marker JnurF13 to genotype restorer fertility (Ms) allele and maintainer sterility (ms) allele of a nuclear gene was confirmed using a set of different onion accessions. The use of molecular marker Jnurf 13 helps to genotype the onion plant in relation to allelic state of the sterility maintainer allele (ms) in plants with N-cytoplasm and shortens the process of developing sterility maintainer lines. Allium roylei is completely resistant to downy mildew which is controlled by a single dominant Pd1 gene. Marker DMR1 of onion downy mildew resistance gene was studied using an accessions of Timofeev’s plant breeding station (RSAU – MTAA) involved in a breeding programs and commercial cultivars of foreign companies.

Keywords: onion (Allium cepa L.), cytoplasmic male sterility, DNA markers, downy mildew, resistance gene, restorer fertility, maintainer sterility.

Ecological and variety variability morphometric parameters of carrots seeds

The article is devoted to the study of the effect of varietal and environmental factors on the variability of morphometric (seed length, endosperm and germ) parameters of carrot seeds. The objects for the study were the original seeds of different varieties grown in 2015, 2016 and 2017. Seeds obtained from two varieties of carrots over the years of research differed significantly in the length of the seeds (P <0.001). The length of the endosperm varieties Boyarynya on average over the years of research was less (P <0.001) compared with Shantane 2461. The experiments were conducted in 2015-2017 at the West Siberian Vegetable Experimental Station in the southern part of the Pervomaisky district of the Altai region. The prevailing soils are leached and ordinary chernozems. Experiment replication is 3, each repeatability consists at least 20 seeds. The measurement of the length of the seed and the endosperm was carried out with Vernier caliper (GOST 166-89), the length of the embryo was determined using microscope Mikromed and video-ocular DCM 300 MD. Seeds were soaked in 14% aqueous sodium hypochlorite solution for 1 h, and then measured the length of the seed, the endosperm and the embryo, and calculated the ratio of the length of the embryo (E) to the length of the endosperm (S). Embryo length was also significantly different (P <0.001) depending on the variety. The environmental factor had a significant impact on the length of the seed (P = 0.005) and endosperm (P = 0.003). The length of the embryo was mainly affected by the factor of the variety (P <0.001). The ratio of the embryo length to the endosperm length was largely influenced by the factor of the variety (P = 0.006). Our studies have shown that the variability of the morphometric parameters of seeds is due to both the influence of the variety and the conditions of the year of reproduction. In comparison with other elements of the seed, the embryo length varies more and depends more on the influence of the hereditary factor. This allows us to conclude about the possibility of a selection change in linear as well as relative sizes of the morphological elements of the seed.

Keywords: Daucus carota, varieties, ecological factor, morphometry, seed, endosperm, embryo.
