In 2020–2023 seven winter wheat varieties were tested in comparison with the standard ‘Volzhskaya K’ and the variety ‘Moskovskaya 39’. The adaptability of the varieties was determined according to the method of A.V. Kilchevsky and L.V. Khotyleva (1985), S.A. Eberhart, W.A. Russell (1966). Weather conditions during the years of study (drought in 2021 and 2023, excessive moisture in 2022) made it possible to evaluate varieties for drought resistance, determine their resistance to lodging, and the ability to use favorable conditions to form high yields. It was revealed that the most adapted varieties were ‘Cheberina’ and ‘26.12/6’, in 2021–2023 they formed the highest yield (50.0–50.1 hwt/ha) and provided a significant increase of 5.5–5.6 hwt/ha to the standard variety ‘Volzhskaya K’. These varieties significantly exceeded the standard variety in general adaptive capacity (GAC). There was found that the varieties ‘Lyubava’, ‘2.05/3’ and ‘Cheberina’ were the most valuable breeding varieties that combined high productivity with a stable yield. The varieties ‘Cheberina’, ‘26.12/6’, ‘Volzhskaya K’, ‘A-332/2’ were highly responsive to improved environmental conditions (bi > 1). Based on the study results, the adaptable, highly productive variety ‘Cheberina’ was sent to the state variety testing. There has been established that the variety forms a strong elastic stem of medium height, resistant to lodging, and increases ear weight and length, and its grain content in favorable conditions of the spring-summer period. An estimation of disease infection during the spring-summer growing season in 2022 showed that the variety possesses complex resistance to powdery mildew, leaf rust, and blotch of an ear and leaves. The variety formed grain of the third class with such indicators as 66 % of kernel hardness, 779 g/l of grain nature weight, 28 % of gluten of the first quality group, 12.8 % of protein in grain.","PeriodicalId":508743,"journal":{"name":"Grain Economy of Russia","volume":" 32","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141832903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the strategy of doubling haploids induced in the culture of gametic cells and tissues in vitro, through androgenesis, gynogenesis and distant hybridization, it became possible to significantly reduce the time for developing new varieties. Using the technology of doubled haploids, within one or two generations, it is possible to obtain aligned homozygous lines, which can both help speed up the breeding process and study several scientific and practical issues. Another promising tool for developing lines and samples with specified traits within several generations is genome editing (engineering) using various nuclease-based engineering complexes. The CRISPR/Cas9 genome editing technology, which came into use ten years ago, allows solving a wide variety of problems in plant functional genomics, including engineering resistance to biotic and abiotic stresses, improving productivity and product quality. The technology is better than the most known methods for improving varieties for the traits which have mono- or polygenic control, since it allows changing several genes simultaneously, which is important for polyploid species. An integral part of plant genome editing, as well as haploidogenesis technologies, is cell and tissue culture in vitro, which gives possibility for their combination. The combination of technologies allows producing homozygous plants with new gene-specific mutations, which improves genetic diversity and accelerates the selection of linear material with new economically valuable traits. The current review has summarized the experience of combining haploidy and genome editing methods in spiked grains of the Triticeae family. In addition to analyzing the current state, there have been considered the prospects for further development of technologies for obtaining haploids of wheat, barley, triticale, and rye with an edited genome.","PeriodicalId":508743,"journal":{"name":"Grain Economy of Russia","volume":" 47","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141833186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objects of research were 12 pea samples developed by the ARC “Donskoy”. The zoned variety ‘Aksaisky Usatiy 5’ was used as a standard. Quality characteristics of peas, such as protein percentage in seeds and their ability to boil soft, are highly dependent on environmental conditions and often have a negative correlation with seed productivity. One of the goals in pea breeding is to change this inverse correlation between productivity and seed quality. The mean productivity of the varieties and lines in the Competitive Variety Testing through the years of study was 3.66 t/ha on average. The standard ‘Aksai Usatiy 5’ (3.46 t/ha) was reliably exceeded by such varieties and lines as ‘G-1181’ (4.17 t/ha), ‘Kazak’ (4.02 t/ha), ‘AKM’ (3.99 t/ha), ‘G-1313’ (3.80 t/ha).

The objects of the study were spring barley seeds selected in the Kemerovo region, growth-stimulating microorganisms isolated from them, and consortia formed on their basis. During the study, there were isolated and tested 9 bacterial isolates for their ability to synthesize growth-stimulating substances (kinetin and indolyl-3-acetic acid). There were selected three strains with the best indicators SHv-2, SHv-5, SHv-6 for further studies. There has been found that the strains are capable of fixing nitrogen (SHv-2 – 800 µg/ml; SHv-5 – 210 µg/ml; SHv-6 – 840 µg/ml). There was also seen an ability to solubilize phosphates (SHv-2 – 2.53; SHv-5 – 1.25; SHv-6 – 3.33). The study of cultural, morphological and biochemical properties made it possible to identify such strains as SHv-2 – Pantoea allii; SHv-5 – Raoultella ornithinolytica; SHv-6 – Pantoea ananatis. Based on these microorganisms, there were made various variants of microbial consortia, which were also valued for their ability to produce growth-promoting substances and fix nitrogen. Consortium MC-7 composed with Pantoea allii, Raoultella ornithinolytica, Pantoea ananatis in a ratio of 1:1:3, respectively, showed maximum activity in terms of the studied parameters. Field trials of this consortium have shown that it successfully improves spring barley productivity.

The variety ‘Antey’ was developed by individual selection from a hybrid combination (Varyag x Novosibirets) x Batrak. The species of the variety was ecaducum. On average, over the years of testing (2020–2022), the variety ‘Antey’ reliably differed from the standard variety ‘Batrak’ in terms of a set of breeding valuable traits. This variety has the most important economic and biological indicators, such as high productivity (2.75 t/ha), resistance to lodging (5 points), low susceptibility to diseases (4.5 points), high protein percentage (23.5 %). Based on phenological observations of pea crops, there have been identified some morphological features of this variety. The variety ‘Antey’ is a middle maturing one. The vegetation period lasts 70...75 days. The variety is determinate, plant height is 65 cm. The leafless type and compressed internodes of the new pea variety increase the resistance of shoots to lodging. The plants bear white flowers of medium size. Beans are shelled, straight. The number of seeds in a bean is 4–7. Our research has shown that over the course of three years in the Competitive Variety Testing, according to the above-mentioned traits, the variety ‘Antey’ significantly exceeds those of the standard variety ‘Batrak’, which made it possible to send this pea variety to the State Variety Testing in 2022.

Under the conditions of the Predkamsk zone, the prevailing contribution to the total variance of the traits \"drift from the sieve 2.8 x 20 mm\", \"coarseness\", \"weight of 1000 grains\", \"bulk grain weight\", \"drift from the sieve 2.5 x 20 mm\" was made by the factor \"year\", which accounted for (in descending order) 81.7...80.3...76.6...76.2. 68.7 %, respectively.","PeriodicalId":508743,"journal":{"name":"Grain Economy of Russia","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140258827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
