The Genetic and Economic Impact of the University of Arkansas’s Rice Breeding Program: 1983–2007

This study estimates the proportion of rice yield increase in University of Arkansas Division of Agriculture’s (UofA) released rice cultivars that are attributable to genetic improvements through the University’s breeding program. Test plot data from eight UofA experiment stations were used to quantify the yield increases and potential yield growth decreases over time. In addition to quantifying the yield and yield variance evolution at the UofA, this study also calculates the economic benefits of the UofA rice breeding program. Results indicated that by releasing modern rice cultivars, the UofA rice breeding program increased average producer yield by 0.68 bu/ac annually. During the last decade, 1997–2007, the average annual economic benefits were 34.3 million (2007) dollars. When accounting for the spillover of UofA rice varieties to neighboring states the average annual economic benefit of the breeding program increases to 46.7 million (2007) dollars.
