Abstract:

The present study entitled morphological characterizations of soybean genotypes in response to charcoal rot disease under sick plot conditions was carried out at Department of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the year 2018-19 to evaluate various genotypes of soybean for charcoal rot resistance. Charcoal rot disease caused by Macrophomina phaseolina is one of the most damaging diseases of soybean resulting to 70 % losses and till date no immune genotype is known for the same. Various limitations inherent in field experiments may have hindered progress toward identifying new source (s) of resistance and breeding resistance in soybean. Field testing under supervised conditions may compliment or help to overcome the losses caused by the disease.

The genotypes were screened under sick-plot during Kh-2018 having virulent colonies of M. phaseolina. Disease infection was observed and genotypes were categorized accordingly. Four genotypes including varieties viz., AMS MB 5 -18, AMS MB 5-19, AMS 77 and AMS 1001 were identified as resistant to M phaseolina while others ranged from moderately resistant to highly susceptible.
