Abstract
Common bunt is one of the most dangerous diseases of wheat, the causative agent of which is Tilletia caries (DC.) Tul. It turns the seeds of cereals into a mass of black dense trimethylamine, completely destroying them. Along with the reduction of damage from common bunt, the quality of the harvested grain decreases. To protect wheat from common bunt, it is important to create and grow sustainable varieties in agriculture.The most effective method of combating common bunt is genetic protection, which allows the introduction of wheat samples resistant to common bunt into production. The aim of the study is to determine the resistance of wheat samples to Tilletia caries (D.C.) Tul spores.For the study, 10 samples of Romanian wheat were taken and used as an unstable standard for common bunt Bogarnaya 56. As a result of the study, 9 wheat varieties were identified, which turned out to be highly resistant to diseases. These are: PARTENER, RETEZAT, F08126G1, F08245G1, F06659G-1, F06393GP10, F08347G8, F08034G1 and F07270G2. As a result of the calculation of the biomass index, the (NDVI) index of two genotypes was recognized as high. As a result of the analysis of structural traits, varieties PARTENER, F08245G1 and F08347G8 were rated as high in four identical traits.Wheat samples that have been identified as resistant as a result of the study can be submitted as donors against common buntTilletia caries (D.C.) Tul in the breeding program.
