Sažetak
Svrha ove studije je da se ispita stabilnost broja zrna po klasu u kolekciji ozimih genotipova ovsa u različitim klimatskim uslovima. Analizirani biološki materijal sastojao se od 73 genotipa ovsa, ispitivanih tokom perioda od tri godine. Eksperimentalni podaci su dobijeni biometrijskim merenjima i naknadno obrađeni korišćenjem sledećih modela linearne regresije: Finlai-Vilkinson, Hardvick-Vood, Muir i Vrike. Broj zrna po dobijenim klasu varirao je u zavisnosti od godišnjih klimatskih uslova i po srednjoj vrednosti i kao intrapopulacijska varijabilnost. Sorte Jefferson, Carrie i Florina, kao i linije 4458, PA 725-4743 i PA 822-818, pokazale su visoku dinamičku stabilnost povezanu sa iznad-prosečnim vrednostima broja zrna po klasu. U odnosu na ovaj pokazatelj, ukupno 53,10% interakcije između genotipa x i okoline je rezultat heterogenosti varijanse.
