The article covers the results of studying antioxidant activity (AOA) in 178 accessions belonging to seven corn subspecies in 2017-2019. The accessions come from 14 countries, including 120 from Ukraine, and have various pigmentation of kernels. It was found that the antioxidant activity of kernels varied within 22.6-82.7%; the chlorogenic acid equivalent (CGAE) varied within 0.97-2.41 µg/g. Antioxidant activity depends on different factors, including growing conditions, origin, subspecies and grain color. Valuable starting material was selected to create lines and hybrids combining elevated AOA with valuable economic characteristics: high grain yield (SS 390, SS 356, MS 11, SE 406, SE 409, SE 416, RK 540-1 KTs 207-1, KTs 42-3, UP 229, Blondynka (UKR), Blu Corn (MEX)); high weight of 1000 kernels (KTs 807-5, KTs 42-3, KTsS 814-2, KTs 602-2, VN 1 (UKR), Freed White, Z 03-004 (USA)); high kernel number per cob (SS 308, MS 233, KTs 27-5, KTs 11, SE 414, SE 397, UP 208 (UKR)); long cobs (Blu Hopi (MEX)); high cob number per plant (VN 1, KTs 502-1 (Ukraine), Butter and Sugar Corn (USA), TAIL P1 (MEX)). The studied accessions are in the collections of Ustymivka Experimental Station and the National Center for Plant Genetic Resources and can be used by breeders and other consumers in theoretical and practical studies.\u0000Conclusions. The presented characteristics of 178 corn accessions in terms of total antioxidant activity revealed variability across accessions belonging to different subspecies from 20% to 82%. AOA depends on different factors, including weather conditions during cultivation, subspecies, and grain color. We selected corn accessions combining high antioxidant activity with high grain productivity, 1000-kernel weight, high kernel number per cob, long cobs, and high cob number per plant. It is expedient to involve corn lines originated from these accessions in the breeding of heterotic hybrids, which will become potential sources of antioxidants in foods.","PeriodicalId":306712,"journal":{"name":"Genetičnì resursi roslin (Plant Genetic Resources)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127965866","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}

Expression of economically valuable traits and their environmental plasticity were studied in female maternal sunflower lines, including lines bred at NAAS institutions. Analyses of variance and regression showed that the lines were ranked according to the genotypic effect and the regression coefficient of these traits. Sunflower lines, which give relatively high yields and demonstrate optimal responses to the year conditions, are recommended to use in breeding for adaptability: short-season line Skh 1006 A (1.48 t/ha), early ripening line Skh 503 A (1.56 t/ha) and mid-early line Od 1042 A (1.60 t/ha). Early ripening line Skh 1002 A (50.4%) and mid-early line Od 1024 A (50.1%) are recommended to use in breeding programs as sources of high oil content and optimal expression of this trait across the years. Line Skh 51 A with a consistently high 1000-achene weight is a valuable source of large seeds. Mid-early line Od 1024 A is noticeable for a stable 1000-achene weight across the years and can serve as a valuable source in breeding programs to achieve a desirable level of this trait.

To evaluate the composition and breeding potential of a gene poolcollection of sweet cherry varieties of M.F.

Moench) varieties from the gene pool collection of MelitopolExperimental Station of Horticulturenamed after M.F. Sidorenko of the Institute of Horticulture of NAAS are presented. The history of the collection creation and the genealogy of modern Ukrainian varieties were analyzed. We found that they were the 1st and 2nd generations of traditional Western European varieties. Major sweet cherry varieties that had been most often used in developing modern Ukrainian assortment, were identified. Analysis of the collection showed that 111 accessions of 129 were varieties bred in Melitopol, 40 of which are officially registered.The other accessions are elite forms, which failed the state variety trials or are being tested according to the competitive design. Among the latter, promising forms (candidates for varieties and pre-breeding forms) were distinguished, as they are sources of valuable economic traits. It was determined that the morphogenic process had contributed to the diversity in fruit quality features, which enabled building up a trait collection of sweet cherries for 20 traits with 82 levels of their expression. However, morphogenesis almost did not affect the growth power, fructification nature, generative organs, fructification time and resistance to diseases, therefore there are no significant differences in these features between the collection accessions bred at Melitopol Experimental Station of Horticulture named after M.F. Sidorenko of the Institute of Horticulture of NAAS. Most of the varieties grown on Magalebian cherry plantlet have extensive crowns, bear fruit on \"May bouquets\" and, after one-year growth, are winter hardy, tolerant to drought, moderately and highly resistant to spur blight and leaf spot as well as self-infertile. On this parent stock, most of the varieties come into fruition after 5-6 years and quickly increase their yields. It was established that enrichment of the gene pool collection with valuable introduced accessions and their wide involvement in hybridization were currently the key objectives aimed at expansion of morphogenesis limits to obtain competitive varieties with high adaptability, productivity and marketability.\u0000\u0000Conclusions. Modern Ukrainian varieties are the 1st and 2nd generations of traditional Western European varieties. German variety Drogansgelbeknorpelkirsche (DroganaZhyoltaya) with its clone Napoleon Belaya and Russian-Ukrainian variety Valeriy Chkalov were the most actively used in their development. 86% of the gene pool collection of MelitopolExperimental Stationof Horticulture named after M.F.

To enrich the database of varieties – sources and donors of valuable traits via analysis of data on expression of adaptability and performance characteristics.\u0000Results and Discussion. At present, there are 736 varieties in the ampelographic collection of the V. Ye. Tairov Institute of Viticulture and Winemaking. The largest portion contains Ukrainian, Russian and Moldavian varieties. More than half (59 %) are table varieties; one third (31%) are wine ones; and 10 % are universal varieties and varieties that are still being studied. As to the ripening period, a group of early-ripening, mainly table varieties (23 %), stands out. The most numerous portions of the collection are mid- and late-ripening varieties (17 % each). The percentages of early-middle and mid-late varieties are similar (11 and 12 %, respectively). Among the berry colors, white and its variations (yellow, yellow-green, amber, etc.) account for 44 %; black – for 23 %; and pink – for 6 % of the collection accessions. There are varieties with red-violet, white-pink, yellow-pink, pale red or bright red berries. Significant diversity was also found in flavor characteristics of the collection accessions. Even in the largest group with so-called “simple taste” (86 % of the collection accessions), varieties with bright prune, solanum, flower, honey and other aromas were found. Varieties with muscat flavor remain in high demand on the market. It was found in 12.5 % of varieties, which can be used in further breeding process. The collection contains 7 % of seedless varieties. Among the collection accessions with their diverse genetic and geographical origin, 82 % have low winter hardiness and frost tolerance and are damaged even at –20 – 21oC. They are mainly European varieties without genetically determined mechanisms of protection against low temperatures and overwintering conditions. 17.9 % of the collection accessions vary from relatively frost tolerant (−22 – 24oC) to frost tolerant (−26–28oC). More than half of the collection accessions (64.5 % ) are susceptible to fungal diseases, since they derive from non-resistant varieties. They are mainly intraspecific Vitis vinifera L. varieties. They are used in crosses as donors of product quality characteristics. A third of varieties showed relative resistance to diseases (6–7 points on a 9-point scale (Bankovska, 2007)).
