Abstract | ||||
Nine Fusarium species, isolated from cotton seedlings infected with damping-off, were compared by double diffusion (DO) technique to determine their serological relationships. On the basis of serological relationships, species were grouped by cluser analysis and the results were expressed as phenograms. Fusarium species were divided into two distinct groups. The first group included F. subglutinans. F. moni/dorme. F. semitectum, and F. so/ani, while the second group included F. semnucinum, F. oxysporum, F. sporotricholdes, and F. pose. The use of common antigens or common specific antigens gave the same taxonomic relationships. Regression analysis was used to quantify the relationship between the no. of common antigens (x) shared by Fusarium species and cotton cultivars and pathogenicity (Y) of these species on these cultivars. Coefficient of determination (R ) of the obtained models ranged from 0.81 to 0.90. These results Indicate that 00 test constituted a positive test to quantify pathogenicity of Fusarium species on cotton cutlivars. | ||||
