This monograph presents the results of researches carried out in oats, grown in conditions of organic production, obtained by analysing the morphological properties of the plants and chemical properties of the oats.
The research was carried out in 2015 and 2016, on 11 oats genotypes, of foreign and domestic origin: Krivogashtani, Trebenishta, Kuchevishte, Rajac, Slavuj, Lovken, Kupa, Baranja, Eksplorer, Shampionka and Istra.
The results show that the variety Kupa has the lowest plant height among all examined genotypes, while the variety Krivogashtani has the highest plants with a height above 100 cm. Since the height of the plant is in a negative correlation with the resistance of the lodging, the varieties suitable for breeding are: Kupa, Eksplorer, Trebenishta and Istra, whose height is less than 100 cm.
The longest tassel in the period of the two years research have the varieties Lovken and Krivogashtani, with 21,5 cm and 26,8 cm respetively.
The average grain yield per tassel in the two-year research period ranged from 1,2 g in the Kuchevishte population to 2,8 g in the Istra variety.
The grain yield of oats per unit area, grown in conditions of organic production, in average, for the two-year research period, ranges from 1 833 kg/ha in the population Kuchevishte to 3 633 kg/ha in the Istra variety.
In our research, the factor genotype plays an important role in the formation of the yield, the number of spikelets in the tassel, the length of the tassel, the height of the plants, and the grain yield per tassel. The factor year, has a decisive role in the formation of the number of grains per spikelet and grains per tassel.
In terms of the chemical composition of the oat grains, the variety Shampionka, in both years of research was distinguished as a variety with the highest protein content: 14.3% in 2015 and 15.3% in 2016. The population Krivogashtani was singled out as the genotype with the highest content of fat in the grain in both years of the research, with values of 4.57% and 4.36%, respectively. The ash content in 2015 was the highest in varieties Shampionka and Baranja (4.2%), and in 2016 in the variety Baranja (4.5%). The population Kuchevishte was characterized by the highest cellulose content in the grains in 2015 (17.5%), while, the next year they were varieties Rajac (30.2%) and Baranja (30.6%).
The content of proteins, fats and ash are influenced by the interaction between the factors genotype and the conditions of the year, while the cellulose content is strongly influenced by the factor year.
