Abstract

The floral biology of sesame, despite its autogamous nature, is favourably suited for developing hybrids. To produce hybrid seeds in sesame, different techniques are tried. In the present study, attempt were made to produce large quantities of hybrid seed by hand emasculation and pollination method. It was found that 98.64 per cent of the total cost of hybrid seed production was spent towards emasculation and crossing. On an average, one labour could attend 450 and 275 flower buds respectively for emasculation and pollination in an hour. Only 57 per cent capsule set was recorded and the number of seeds formed in the crossed capsule was also less. The production cost of hybrid seeds was worked out to be Rs. 534.00 per kg.
