Abstract
In the forest–steppe agro-climatic zone of the Ryazan region, 25 genotypes of spring barley of different ecological and geographical origin were studied in the fields of the laboratory of breeding and primary seed production of the Institute of Seed Production and Agrotechnologies - a branch of the FSBI FNAC VIM in 2019-2023. The purpose of the research is to evaluate the parameters of adaptability and productivity of spring barley varieties in the conditions of the Ryazan region and to identify the most promising genotypes for further breeding work. All calculations are based on the "yield" attribute. It was revealed that 17 varieties (68.0%) exceed the standard Reliable variety in yield by 0.06–1.03 t/ha (101.0–116.9%). The Polish Stratus variety had the highest average yield – 7.12 t/ha. The maximum yields over the years of research (8.0 t/ha or more) were shown by the varieties Batka, Magutny, Fest (Belarus); Bambina, CWS Vermont, Chill (Germany); Cheerlo, Rapid, LG Nabucco (France); Crossway (Denmark); Stratus (Poland); Lenetah (USA); Duncan (Canada); Laureate (Switzerland). Of all the studied indicators, the coefficient of adaptability (KA) has a close (close to functional) relationship with yield (r= + 0.971), which indicates the importance of this indicator in increasing the further productivity of the crop. It was found that Jaromir, Znatny (RF), Batka, Gonar (Belarus), Ilek-16 (Kazakhstan), Prosa (Czech Republic), KWS Vermont, Rapid, LG Nabuco, Crossway, Stratus have a KA>1.0. To identify forms with a wide adaptive potential, the most valuable is a comprehensive rating of quantitative characteristics of adaptability, which identified the varieties Stratus, Yaromir and Crossway. The selected source material is recommended to be involved in breeding hybridization programs to increase the adaptive properties of the varieties being created.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
