Phenotypic traits that potentially influence methane emissions
from rice production systems include:
•Tiller numbers
•Leaf area index
•Grain starch content
•Duration in the field
•Aerenchyma structure
In an on-going experiment in CIAT, Colombia, we are evaluating
four rice genotypes to determine differences in methane
emissions and the phenotypic traits listed above.
Introduction
Methodology
Results
Figure 2. Daily methane emissions from four different rice
genotypes (dates circled in blue indicate days when fertilizer was
applied).
Preliminary Findings
Methane emissions were quantified through static chamber
technique and gas chromatography.

Turning to rice cultivars for solving the methane puzzle
in irrigated rice systems

•Methane emissions increase with plant biomass
•Varieties showed lower CH4emissions compared to hybrids
•Yield data pending
•There is potential to exploit genotypic variation to achieve
low emission rice production systems
