Abstract:

Mustard is one of the important oilseed crop in the country. It contributes 26.5 % to the total domestic edible oil production. Alternaria blight is one of the major factor in the reduction of yield and quality which ranges from 15-71 % depending upon the severity of the disease. The present study was undertaken to evaluate diversity among different isolates of Alternaria brassicicola collected from various regions of Bihar and adjoining parts. A total of sixteen isolates were collected from Saharsa, Supaul, Darbhanga, Khagaria, Samastipur, Bhagalpur, Gaya, Munger and Varanasi and its cultural, morphological, pathological, biochemical and genetic variability were studied. Isolates showed variability with respect to colony characters from olive gray to dark brown, radial growth rate ranged from 4.6 mm/day to 11 mm/day, and sporulation capacity showed variation from 33×104 spores/ml to 134×104 spores/ml. Substantial variation was found in spore morphology with respect to conidial length, width and number of septa. Incubation period of isolates varied from 48 hours to 96 hours. There was significant positive correlation between growth rate and sporulation (r=0.74).
