Abstract

Goal. Selection of spring barley accessions of different geographical origin by economic traits (yield capacity, productivity, 1000-seed weight).

Results and Discussion. The article presents the results of a 2-year study of economic traits of 145 spring barley accessions originating from 14 countries. Spring barley accessions were categorized into three groups according to the yield capacity level. The moderate yield was observed for three accessions, which were included in group 4-5 (85.1-105.0% related to the standard). One spring barley accession, Nemchinovskiy 36 IR 08642 originating from Russia exhibited a deviation of 88.5% related to the standard. Group 2-3 (65.1-85.0% related to the standard) consisted of 23 accessions with low yields. Group 1 comprised 119 accessions with very low yields (by 65.1% lower than the standard). Based on plant productivity,  spring barley accessions were divided into five groups: Group 9 with very high of productivity included 24 accessions; Group 6-8 with high productivity (105.1-135.0% related to the standard) - 40 accessions; Group 4-5 with moderate productivity (85.1-105.0% related to the standard) - 40 accessions; Group 2-3 with low productivity (65.1-85.0% related to the standard) - 20 accessions. The last group, Group 1, with very low productivity (by 65.1% lower than the standard) consisted of 19 accessions. Of barley varieties bred in Ukraine, seven varieties exceeded the standard in terms of productivity by 136.4-184.8% - Stepovyk,  IR 08638, 08-696, IR 08451, Vіtrazh, IR 08667, 08-87, IR 08404, Galychanyn, IR 08553, Skhіdnyy, IR 08550, 08-2447, IR 08447. Six accessions from  Russia significantly exceeded the standard (by 139.4-190.9%) in terms of productivity - Yasnyy, IR 08507, Acha, IR 06825, T - 12, IR 08645, Buyan, IR 08644, Vladuk, IR 08594, Vladimir, IR 08482. Four accessions from Canada (Sedna, IR 08343, CDC Mindon, IR 08341, AC Ranger, IR 08338, Ascension, IR 08342) had 163.6-187.9 % higher productivity than the standard. Productivity of three accessions of Kazakhstan origin (Arna, IR 08577, Tselinnyy 2005, IR 08581, Turan 2, IR 08,573) and four accessions from the Czech Republic, Syria, Germany, Norway (one accession from each) was by 136.4-166.7% higher than the standard. We distinguished two spring barley accessions that were are characterized by moderate yield capacity and high productivity - Naran, IR 08243 and Oleniok, IR 08592 (Russia). Very high values ​​of 1000-seed weight were detected in four accessions from Ukraine - Skhіdnyy,  IR 08550, Krok, IR 08599, Dorіdnyy, IR 08601, 08-696, IR 08451 (56.0-58.3 g) and one accession from Russia - T -12, IR 08645 (55.5 g). Group with very high weight (over 50.0 g) was formed by 29 accessions originating from Ukraine (15 accessions), Russia (8), Syria (three) and three accessions from Kazakhstan, Canada and Germany (one accession from each). The bulks of the collection material, that is, 91 accessions had high 1000-seed weight and were assigned to Group 4 (42.1-50.0 g). The group with moderate weight (38.1-42.0 g) included 14 accessions: six - from Ukraine, three - from Russia, two - from Syria, and three - from Belarus, Canada, Kazakhstan (one accession from each). Group 2 with low weight (34.1-38.0 g) was formed by eight accessions, including those from Ukraine (five), Russia (two), Kazakhstan (one). Very low 1000-seed weight (lower than 34.1 g) was recorded for three accessions originating from Ukraine (two samples) and Canada (one), which were assigned to Group 1. The study highlighted the 24 best accessions from the collection spring barley material, basing on their  yield capacity (50.9-102.4% related to the standard), productivity (109.1-190.9% related to the standard), 1000-seed weight (40.8 -58.3 g). Among them, there are nine accessions from Russia, six - from Ukraine, four - from Canada, and 5 - from Syria, Kazakhstan, Czech Republic, Norway and Germany (one accession from each).

Conclusions. In 2014-2015, 24 valuable spring barley accessions of the NCPGRU were distinguished by economic traits (yield capacity, productivity, 1000-seed weight). Further research is needed to categorize the accessions as sources of valuable traits.
