Resistance evaluation of Dayecaoying to crown gall disease
摘要
Abstract
In order to evaluate the resistance of Dayecaoying to crown gall disease, pot seedlings were used as test materials via artificial inoculation, mainly to A. tumefaciens Conn and A. rhizogenes Conn. The results showed that Dayecaoying was excellent germplasm resource resisting to crown gall disease. At 60 days after inoculation, the disease index of Dayecaoying to A. tumefaciens Conn was 23.65,while it was 18.63 to A. rhizogenes Conn. According to the resistance evaluation standard to Crown gall disease, it moderately resisted to A. tumefaciens Conn and was separated into 5 types of disease resistance, including being immune, highly resistant, moderately resistant, low resistant and susceptible with corresponding percentages of 32. 69%, 31. 73%, 24. 04%, 7. 69% and 3. 85% respectively.And it was highly resisted to A. rhizogenes Conn and was divided into 3 types of disease resistance according to the evaluation standard with corresponding percentages of 16.67 % ,73.53% and 9.80% respectively.关键词
