Interpretive Summary:

Technical Abstract: Agriculture is recognized as a significant contributor to greenhouse gas emissions (GHGE) globally. Paddy rice is a significant source of methane emissions. Methane accounts for about 11% of all U.S. GHGE and it is ~25 times more potent in global warming potential than carbon dioxide. Research has shown that the amount of methane emitted from paddy rice can vary by cultivar indicating that genetics has the potential for mitigating the effects of GHGE. Our preliminary data indicate in situ variation among rice varieties for methane flux under paddy conditions. However, the physiological and morphological factors which are responsible for this are little known. We investigated genetic variation in CH4 emissions among 5 rice cultivars, and found that root and tiller production are largely linked with variation in CH4 emissions. We are further studying the detailed relationship of root and tiller production in CH4 emissions using a biparental mapping population segregating for these two traits.
