Sunflower diseases have a major impact on sunflower yield and quality of seed. When conditions during vegetation are favorable, the intensity of damage can be very high. Therefore, surveys of economically important diseases are necessary. A survey of incidencesand severity of phomopsis stem canker was performed on 9 locations during 2007 and 2008. A total of 8 hybrids per location was examined. Lodging of plants as a symptom of stem canker disease was not detected. The mean disease incidence was less than 5%, depending on hybrid, location and year. Generally, higher deasease incidence was recorded in the first year of survey than in the second. The hybrids Velja, NS-H-111 and Baća demonstrated an elevated level of resistance. Despite significant differences in disease severitythat was found among the hybrids tested, all of them were highly resistant to phomopsis stem canker. |
