Adaptability of high-protein barley genotypes under the conditions of the Volga-Vyatka region I. Yu. Zaytseva, I. N. Shchennikova, L. V. Panikhina, E. V. Dyagileva Proceedings on Applied Botany Genetics and Breeding, 2022 Background. Barley grain is unique raw material of versatile uses. More than 60% of the grain produced In the Volga-Vyatka region goes directly to fodder production purposes. One of the urgent tasks is to develop high-yielding cultivars with good grain quality, thus reducing protein deficiency in farm animal feeds and meeting the need for fodder grain that increases every year. Its successful solution requires a search for new high-yielding and high-protein source genotypes adapted to the conditions of the Volga-Vyatka region and their involvement in the breeding process.Materials and methods. Experimental work was carried out in 2018–2020 at the Federal Agricultural Research Center of the North-East named N.V. Rudnitsky, Kirov. Protein content in grain, yield, resistance to lodging, and duration of the growing season of 31 barley accessions were assessed. The barley collection was studied according to the International COMECON List of Descriptors for the Genus Hordeum L. and Methodological Guidelines. Protein content was measured using a universal rapid analyzer (INFRAMATIC 8620).Results and conclusions. Protein content had a strong correlation with Selyaninov’s hydrothermal coefficient in the interphase period from ear emergence to maturity (r = 0.85); the sum of effective temperatures during the entire growing season (r = 0.75); and precipitation in the period from seedling emergence to maturity (r = 0.67). Traits of breeding value (yield, lodging resistance, environmental plasticity, and stability) were observed in the following accessions: k-30574 (‘Filippa’, Sweden), k-30256 (‘Rodos’, Poland), ya-52 (‘Crusades’, Great Britain), k-35415 (NCL 95098, Argentina), k-30892 (‘Naran’, Russia), k-15619 (‘Polyarny 14’, Russia), ya-4 (752A, Switzerland), k-30349 (Landrace, Peru), k-5983 (Local, Afghanistan), k-3506 (Local, India), k-2929 (Local, China), k-2930 (Local, China), and k-5210 (‘Makbo’, Australia).
Initial material for breeding drought-resistant varieties of spring barley in the conditions of the Volga-Vyatka region I. Yu. Zaytseva, L.V. Mamaeva, I. N. Shchennikova, L. P. Kokina, E. V. Dyagileva E3s Web of Conferences, 2021 Water scarcity has a significant impact on plants, quality and quantity of crops. On the soils of the northeast of European Russia, instability of precipitation is one of the main factors negatively affecting barley productivity. To assess the drought tolerance level, we used the RSR (root-to-shoot ratio) indicator, which shows the relative redistribution of fluxes of plastic substances between root and aerial organs. Evaluation of 57 collection accessions of spring barley of various ecological and geographical origins was carried out. As a result of the research, sources of breeding of valuable traits were identified for further breeding work on the creation of barley varieties adaptive to the conditions of the Volga-Vyatka region. The accessions Bonita, Bionic, Cooper, Danuta, 752A, NCL 95098, local sample from India (k-3506), Odessky 115, Rodos, Kazminsky, Polarny 14, Adam, Bear, Medicum 11, Irbe (PR-3528), Mie, 121–13, and C-105 are characterized by resistance to osmotic stress at the early stages of organogenesis. For further breeding work drought-resistant varieties NCL 95098, Cooper, Bonita, Danuta, Mie, Rodos, Kazminsky, Adam, Bear, Medicum 11, Irbe (PR-3528), 752A, Polarny 14, and C-105, distinguished by the elements of plant productivity, are advisable to use taking into account their positive qualities. The rest of the drought-resistant accessions are recommended to be included in crosses with varieties having higher productivity.
