 ABSTRACT

The seedborne nature of Botrytis ricini L. was tested using the component plating technique and transmission of B. ricini from castor (cv. DCS-9) seeds to seedlings was studied in laboratory as well as in glass house conditions. Component plating technique revealed that, B. ricini incidence was maximum in caruncle and seed coat in both naturally infected and artificially inoculated castor seeds. Whereas B. ricini incidence was totally absent in embryo in both naturally infected and artificially inoculated seeds. Studies on Transmission revealed that, seed rotting was maximum in naturally infected unsterilized seeds and germination percentage was higher in artificially inoculated sterilized seeds in paper towel. Seedling mortality and seedling infection were very low when compared to seed rotting. Whereas in sand and soil methods seedling infection was totally absent and seed rotting was maximum in naturally infected unsterilized seeds.    

Keywords: Component plating technique, transmission, seed rotting, seedling mortality.
