Abstract: The research was conducted during 2015 and 2016 of 11 oats genotypes in conditions of organic production. Three of the genotypes are domestic (Krivogastani, Trebenista and Kuceviste), 3 genotypes are from Serbia (Rajac, Slavuj and Lovken) and fi ve genotypes are from Croatia (Kupa, Baranja, Eksplorer, Sampionka and Istra). The genotypes showed different average values almost for all analyzed yield components and according to the signifi cance
of the differences they are divided in groups. Of all the genotypes cultivated in the Strumica region, the highest total grain yield had varieties Kupa (3 850 kg/ha and 2 866 kg/ha) and Istra (3 600 kg/ha and 3 666 kg/ha). The 11 varieties tested are divided into 3 clusters. The third cluster includes varieties Kupa and Istra, which are the most high-yielding compared with the rest of the group. The analysis of variance showed that the genotype has the highest infl uence to the yield components: number of spikelet in the tassel, the length of the tassel, the plant height and the grain yield in the tassel. There is a strong positive correlation between the grain yield per tassel and grain yield per 1ha (0.716). From the distribution of the components of the yield and yield of the grain in the factorial plane, we obtained that the yield can be increased only by selecting tassels with a high grain yield.
