Abstract

During growing season of 2005, Potato tubers showing black scurf symptom were collected 1Tommajor growing areas in Khuzestan (Anjilack, Aghili, Sarbisheh, Jareah, Shoush, Shoushtar and Shams Abad). Collectively 130 isolates of Rhizoctonia were recovered by transferring sclerotia to the PDA plates. Morphological characteristics, nuclear number per cell of the young hyphae, ANASTOMOSIS GROUP, temperature requirement and pathogenicity of the isolates were studied. Nuclear staining with Sa1Tanin0 revealed that all isolates were multinucleate. ANASTOMOSIS GROUPs of the isolates were determined using glass slide, covered with water agar. Results indicated that 122 isolates were AG-3; 3 were AG-4; 3 were AG-5 and 2 were unknown. The effect of temperature on the activity of isolates was determined. Optimum temperature for the growth was 25oC. Effect of different temperatures on sclerotia production by the isolates was investigated. All the isolates belonging to the AG-3 produced the highest level of sclerotia at 25oC. Diversity in the pathogenecity of the isolates was assessed on potato seedlings in petri plates. To do so, germinated potato seeds were placed at the periphery of growing colony of isolates in water agar plates. Disease severity was assessed based on a scale of 0-5 according to the lesion size on the seedling roots after 15 days of incubation. Pathogenecity of the AG-3 isolates was the highest compared to the other isolates. In addition to the Petri plates, diversity in pathogenicity was studied under greenhouse condition. Eighty days after inoculation, there was significant difference in the treatments. Data analysis, according to Duncan's test, showed that control plants had the highest level of growth compared to the other treatments. There was no significant difference among the isolates in stem canker production, but there were significant difference between isolates in causing root rot. In general, AG-3 isolates had higher pathogenecity than the other two AGs and are considered as the principal cause of black scurf.
