Policy-makers, research managers, and donors are interested in knowing the outputs, outcomes,
and impacts of investment in agricultural research. Several institutions are engaged in rice research
and impact assessment of rice research requires area coverage information for rice varieties.
The area coverage information for individual varieties is not available at the national level in
many developing countries as the conventional household survey method is expensive and time consuming.
This article aims to find a cost-effective and quick method to estimate the area under
popular rice varieties in India and their spread in different states. Secondary data collected from
27 states and 1 union territory of India were used to estimate the area. The results of the new
method compared well with some of the studies conducted at the state level. The most important
varieties identified using the new method were Swarna, Cottondora Sannalu, Samba Mahsuri,
Vijetha, IR-64, and Ranjeet, which covered more than 1 million ha each in the country. On geographical
coverage, IR-64 has spread to 17 states followed by Swarna, Cottondora Sannalu,
Samba Mahsuri, Vijetha, IR-36, and Swarna Sub-1 which covered 14, 14, 12, 11, 11, and 10 states,
respectively. The area information can be used to compute returns to rice research by different research
institutions and study dynamics of varietal change over time. The popular varieties identified
should be used in future breeding programs and biotechnological studies for the development
of superior varieties.
