Methane production potential of different varieties of maize grain was tested by in vitro gas production test. The seeds of four normal maize (HTHM 5101, DHM 117, HM 5 and Shaktiman/900 M Gold) and three high quality protein maize (HQPM 5, HQPM 7, HQPM 9/Vivek) varieties were tested for gas, methane production and digestibility using goat rumen fluid by in vitro gas production technique. Gas productions per g dry matter (ml/g DM) and per g digestible dry matter (ml/g DDM) did not show any significant difference among different varieties. Methane production was significantly (P<0.05) higher for HM 5 (11.55%) and lowest for DHM 117 (9.56%) variety. The net methane production per g dry matter (ml/g DM) and per g digestible dry matter (ml/g DDM) was significantly (P<0.05) highest for HTHM 5101 and lowest for DHM 117 variety. The in vitro dry matter digestibility (IVDMD %) and in vitro organic matter digestibility (IVOMD %) differed significantly (P<0.05) among the different varieties of maize grains. The results suggest that different maize grain varieties exhibited differences in their methane production potential and DHM 117 maize variety produced least methane.
