The total phenolic content, compositions, and antioxidant capacity in the grain of 40 purple wheat genotypes were studied. In this study, wheats investigated terms their composition free bound acids 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity. content ranged from 164.25 to 271.05 mg GAE/100 g DW was between 182.89–565.62 wheat. samples 352.65 771.83 Gallic acid, protocatechuic catechin, 4-hydroxybenzoic syringic ellagic m-coumaric o-coumaric chrysin, caffeic p-coumaric ferulic...
Stem rust in recent years has acquired an epiphytotic character, causing significant economic damage for wheat production some parts of Western Siberia. On the basis a race composition study stem populations collected 2016–2017 Omsk region and Altai Krai, 13 pathotypes population 10 were identified. The differentiation using tester set 20 North American Sr genes differentiator lines was carried out. are avirulent only to resistance gene Sr31, isolates not but also Sr24, Sr30. A low frequency...
Climate change is leading to increased occurrence of and yield losses wheat diseases. Managing these diseases by introducing new, effective diverse resistance genes into cultivars represents an important component sustainable production. In 2016 2017 a set primary hexaploid synthetic was studied under high disease pressure: powdery mildew, leaf stem rust in Omsk; Septoria tritici S. nodorum Moscow. A total 28 synthetics (19 CIMMYT 9 Japanese synthetics) were selected as having combined at...
Exploiting genetically diverse lines to identify genes for improving crop performance is needed ensure global food security. A genome-wide association study (GWAS) was conducted using 46,268 SNP markers on a panel of 143 hexaploid bread and synthetic wheat potential genes/genomic regions controlling agronomic (yield 26 yield-related traits), disease resistance, grain quality traits. From phenotypic evaluation, we found large genetic variation among the 35 traits recommended five having high...
The damage to wheat crops by stem rust poses a threat the food security of world’s population. species Thinopyrum ponticum (Podpěra, 1902) (Z.-W. Liu and R.-C. Wang, 1993) is non-host for fungus Puccinia graminis f. sp. tritici Eriks. Henn. (Pgt). Sr24, Sr25, Sr26 genes, transferred from Th. gene pool, protect cultivars disease in different regions world. study resistance (NHR) effects introgressed genes important breeding with durable rust. aim research interaction Pgt common lines addition...
The Septoria blotch is one of the most economically harmful diseases common wheat in Russia and world. disease mainly caused by two pathogen species: Zymoseptoria tritici that damages leaves, Parastagonospora nodorum strikes leaves ears. Resistance genes alien relatives are traditionally used for genetic defense cultivars. aims research were to study resistance tall wheatgrass Thinopyrum ponticum (Podp.) Z.-W. Liu R.-C. Wang perspective introgressive lines spring with its material blotch,...
Common wheat cultivars have been protected from stem rust for several decades worldwide by the Sr31 resistance gene transferred Secale cereale L. (cv. Petkus). In 1998, was overcome in Uganda Ug99 race of Puccinia graminis f. sp. tritici Eriks. & Henn. (Pgt). The and its derivatives spread widely Africa, neighboring regions Europe. However, remains effective other areas world, including Russia. To breed with durable resistance, it is promising to research mechanisms nonhost species...
The growth of the total wheat production and increase yield stability from year to are some priorities agriculture in Russia. commercial varieties significantly diversifies due huge losses their potential under influence negative biotic abiotic factors. Increase resistance stress factors emerging can be achieved by utilizing diversity genetic resources related wild species genera crosses. results a phenotypic evaluation synthetic hexaploid lines CIMMYT breeding created crossing durum...
Abstract Numerous samples with introgressions were obtained in bread wheat result of distant hybridization. However, only a small number them used for improvement modern cultivars such an important traits as protein and gluten content grain. The aim this study is to investigate the phenotypic impact transferred 5B chromosome from species T. durum Ae. speltoides on these grain quality traits. To end, two lines that carried different size developed genetic background cv. Saratovskaya 29 (S29)....
The article presents the results of wheat breeding for period 2019–2022 in and genetic center Omsk SAU. A brief description disease resistant varieties spring bread large-grained wheatgrass (as alternative to perennial wheat) suitable production environmentally friendly grain with minimal pesticide treatment, organic farming under conditions Western Siberia Ural regions is given
The paper highlights that genetic diversity of wheat is the basis for higher resistance plants to bad environmental conditions and crop yield, which can be achieved by including resources similar species varieties in hybridization. authors estimate basic criteria race non-specific leaf stem rust synthetic lines contain Ae. Tausсhii genome. Research was conducted at experimental field Omsk State Agrarian University 2016-2017. explores juvenile during inoculation seedlings 4 isolates Puccinia...
