Immunological clustering of the spring barley gene pool in the conditions of the Ryazan region
Bibliographic record
Abstract
The article presents the results of field studies of the collection gene pool of spring barley in the conditions of the Ryazan branch of the Federal State Budgetary Scientific Institution "Federal Scientific Agroengineering Center VIM" in 2017-2021 against the natural background of the development of fungal diseases. The aim of the research was to carry out immunological clustering of the collection gene pool of spring barley in the conditions of the Ryazan region and to identify the most promising forms for inclusion in crosses as parental forms. It was revealed that the vast majority of the studied varieties belonged to the group of highly resistant varieties. It was found that more than half of the varieties (57.8%) of the studied collection possessed complex resistance to a group of pathogens (reticulated (Perenophora teres Drechs), dark brown mottling (Bipolaris sorokiniana Shoem), powdery mildew (Erisiphe gramminis D.C.f.sp. hordei Marchal), dusty smut (Usnilago nuda Jen.)). spring barley. The following varieties showed high complex stability: Nur, Reliable, Moskovsky 3, Moskovsky 2, Dvina, Kalita, Hopper, Clear, Griv, Miar, Risk, Choice (Russia); Timerkhan (Tatarstan); Divosny, Gonor, Yakub, Batka, Fest, Khago (Belarus); Hetman, Kharkiv 102, Vinnytsia 17 (Ukraine); Ilek-1, Ilek-34 (Kazakhstan); Delphin (France); Linga, Irbe (Latvia); Izotta, Graice (Germany); Prosa, Pejas (Czech Republic); Collie (UK); B-934 (Canada). The greatest approximate productivity over the years of research has been revealed in the following varieties: Notable (Russia), Gonar (Belarus), Vivaldi (Austria), Eufel, Pioneer (France), Stratus (Poland), which have an advantage over the Yaromir standard by 0.3 – 0.7 t/ha. Reliable variety (Russia) had the highest resistance to lodging out of the entire studied gene pool of spring barley – 8.6 points. The use of a comprehensive ranking assessment revealed the priority of varieties of the Belarusian selection Divosny, Gonar and Czech varieties Pegas, Prosa, which occupy leading positions on the rating scale in terms of resistance to lodging, disease damage and productivity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
