Large-scale phenotyping and multi-trait selection identify low-methane Napier grass (Cenchrus purpureus) accessions under contrasting environmental conditions

Abstract Napier grass (Cenchrus purpureus, NG) is an important forage in tropical and subtropical livestock systems, but the extent of naturally occurring variation in its methane (CH4) production and its potential for selecting low-CH4 emitting genotypes remains poorly characterised. This study evaluated variation in CH4 yield among NG accessions, examined the effects of season and water stress,…
