transport capacity (MTC) etc.,. Various cultivars like Ranjit, IR 65598, IR 72, Ko-
shihikari, Pusa 169, IR 65600, KDML 105, PR-108 emit far less CH
4
than that of
other traditional varieties due to some variety-specific properties. Improved cultivar
'Ranjit' emits less CH
4
than 'Agni' due its better photosynthate allocation capacity,
high-yielding varieties like Pusa 169, Pusa basmati, Pusa 677 emit less methane due
to lower root exudation and low MTC.
Thus cultivar improvement in the line of developing new high-yielding variet-
ies having low MTC, lower methane emission through aerenchyma and nodes, low
amount of root exudates, can give the breakthrough in agricultural research system
for reducing CH
4
emission from rice fields on a regional and global level without
hampering the productivity.
