The study was carried out to characterize 32 genotypes of oat based on morphological and quality characters. The data show thatthere isgeneticvariationfor almost all the traits. Thus, the lodgingin the early stageis the sameas thatinthe stage of maturity, butitis observedthat thegenotypesare differentabout thistrait. To distinguish variation in the studied genotypes, the assessment was based on the division into five categories; 46.86% resulting lodging resistant (upright), 6.25% intermediate, while genotypes minor lodging, lodged and extremely lodged (all plants) representing 15.63% of each of them.
To trait the hairiness of leaf sheath (lower leaves), all genotypes are hairless category. For trait lemma color, they appear different genotypes where white – coffee resulting 34.37%, yellow 25%, yellow – brown 8.75% and brown 21.88%. To trait the hairiness of lemma, most ofgenotypesresultinghairless(87.5%), slightly pubescent 3.12% and moderately pubescent 9,37%. This descriptor is important to differentiate the two different species and all traits studied, can be utilized to select superior genotypes related to agronomic values. Genotypes that have a growth habit erect, the nature ofpanicle is erect and the presence of wax should be selected for abiotic stress tolerance.
