Abstract

It is common knowledge that in rice, the short duration varieties readily germinate after harvest, while medium and long duration varieties possess varying periods of after ripening. This trait though advantageous to raise the second crop with the early varieties, cause severe damage, in those regions where the monsoon season synchronise with the time of harvest, by sprouting in the field itself. A period of dormancy, for a month or even 15 days in short duration varieties would help greatly to tide over this collosal waste. To achieve this end, a correct perspective on the extent of sprouting resistance, viability and their association with other characters would be necessary. In this paper 85 departmental strains were studied for their variation in the period of dormancy and viability.
