Expression of Useful Traits in Determinant Buckwheat Accessions in the East of Ukraine

2025-03-24T12:11:28+01:00

The article presents results of studying a collection of determinant buckwheat (Fagopyrum esculentum Moench) genotypes in the East of Ukraine. The purpose of the study was to select highly productive and stress-resistant genotypes for breeding. We noted a considerable variability of biometric and agronomic characteristics between genotypes. The highest productivity (3.2 g/plant) was recorded for accession UC0101058 (UA) and the highest thousand-kernel weight (37.4 g) was recorded for accession UC0100286 (BY). There was a strong positive correlation between the number of kernels per plant and productivity (r = 0.93). Using multivariate statistics methods, we distinguished major clusters of genotypes. Promising accessions (UC0100167 (UA), UC0101058 (UA), and UC0102186 (UA)) were selected for further breeding. Using principal component (PC) biplot analysis, we evaluated genetic relationships between the studied accessions and genetically distant genotypes (UC0101058 (UA), UC0100286 (BY), and UC0100963 (UA)) were identified as potential outliers.

The potential of Si and Se as biostimulants to enhance resistance to climatic conditions and improve yields in common and Tartary buckwheat

2025-03-24T12:22:42+01:00

Common buckwheat and Tartary buckwheat are pseudocereals and grow worldwide. Due to the high concentration of flavonoids, buckwheats are potential sources of smart food. Tartary and common buckwheat are traditionally grown in mountain regions of China, Korea, the northern parts of India, Bhutan, and Nepal. Plants that grow in high elevations are exposed to intense UV radiation, which can harm susceptible sites in the plants. Plants defend themselves against intense radiation by synthesising UV-absorbing compounds. Drought will probably become more frequent and intense due to climate change. UV radiation and drought are environmental parameters that present stress to the plants. These impacts can be synergistic or antagonistic. Selenium (Se) and silicon (Si) can protect plants exposed to UV radiation or drought since Se acts as an antioxidant. Silicon is an abundant element in Earth’s crust. It is present as a liquid or an amorphous or crystalline solid phase in the soil. Selenium and silicon are not essential elements for vascular plants, but they may positively affect plants. Thus, they can be added to the growth media to improve crop yield and quality, enhance resistance to biotic and biotic stress and improve plant growth.

History and Achievements of Buckwheat Breeding in the Republic of Tatarstan

2025-03-24T12:48:33+01:00

Common buckwheat (Fagopyrum esculentum) is an agricultural crop in the Russian Federation, which has been cultivated since the 15th century. Scientific breeding of buckwheat in the Republic of Tatarstan has a history of more than a century century. During this time, 20 varieties of Tatar breeding have been included in the State Register of Breeding Achievements of the Russian Federation in different years. The article presents the history of breeding school and retrospective analysis of methods and achievements in buckwheat breeding at the Tatar Research Institute of Agriculture (before 1969 Kazan Republican Breeding and Experimental Station) on the basis of scientific reports of the laboratory of cereal crops and archival data.

4th European Buckwheat Symposium

2025-03-24T13:03:03+01:00

University of Debrecen, IAREF Research Institute of Nyíregyháza and International Buckwheat Research Association (IBRA) are pleased to inform you that 4th European Buckwheat Symposium will be held on 3–5 September 2025 in Nyíregyháza, Hungary.

EuroIBRA provides opportunity for dialogue and exchange of ideas between European buckwheat experts, so we welcome all interested parties both inside and outside Europe to the event.

Conference participants will have the opportunity to present their professional work, scientific results and practical experiences.
