| Popis: | Tilletia caries Tul. is the main pathogen for common bunt in Ukraine. Most of the wheat varieties grown in the country are susceptible to the disease. Some of the varieties are very seriously affected by the disease that makes it necessary to treat the seed with fungicides. At Plant Breeding and Genetics Institute wheat breeding for resistance to diseases, including common bunt, has been carried out for a long time and especially intensively and purposefully it has been done during the last 12 years. It has been found that in Ukraine the population of Tilletia caries (DC.) Tul. consists of 12 races. Among domestic and foreign wheat varieties some varieties were found to be resistant. Complex resistance to phytopathogens was found to be the best in winter bread wheat lines derived from crosses with Aegilops ventricosa and Triticum erebuni. On the basis of these lines the initial breeding material and the first resistant wheat varieties have been developed. The varieties are being tested in an institute competitive trial. |
