Evaluation of Seed Transmission of Rhizoctonia solani and Seed Mycoflora of Ajwain

In vitro study was conducted Department of Plant Pathology, Rajasthan College of Agriculture, Udaipur (Rajasthan) and evaluated the seed transmission of R. solani from the seeds of eight popular cultivars of ajwain viz., Ajmer Ajwain-1, Ajmer Ajwain-2, Ajmer Ajwain-93, Pratap Ajwain, Lam selection-1, Gujarat Ajwain-1, Azad Ajwain and local cultivar. It was found that maximum recovery of the pathogens was from local cultivar and Ajmer Ajwain-93 exhibited lowest recovery of pathogens. It was also found in this study that there some differential results in recovery of R. solani from seeds of cv. Gujarat Ajwain-1 and cv. Azad Ajwain. Seed samples were collected and results revealed that in all seed mycoflora were detected in both blotter and agar plate test methods from almost all the seed samples and these fungi were Aspergillus niger, Aspergillus flavus, Aspergillus ochraceeous, Alternaria alternata, Rhizopus oryzae, Rhizoctonia solani, Dreschslera australiensis and Fusarium sporotrichioides.
