Identify the Source of Resistant Against Collar Rot of
Groundnut Caused by Aspergillus niger Van Tiegham
Mahendra Kumar Saran
Cultivation of resistant varieties seems to be the most economical and sustainable control measure of collar rot disease of groundnut. Twelve groundnut varieties along with one susceptible check were screened against collar rot disease caused by Aspergillus niger under field condition. Among them none of entry was found immune or resistant to collar rot. Three cultivars TG-37A, HNG-69 and GJG-22 were shown 1-10 % disease incidence and considered as moderately resistant. Four cultivars GG-20, GG-7, GL-501 and GJG-9 were shown 11-20 % disease incidence and considered as moderately susceptible. However, TMV-2 was shown > 51 % disease incidence and considered as highly susceptible reaction.
