Genotype-environment interaction in Gliricidia sepium: Phenotypic stability of provenances for leaf biomass yield

► Results of GxE study in Gliricidia sepium in the tropics and subtropics are presented. ► Significant GxE for dry matter (DM) leaf biomass was detected across the sites. ► Retalhuleu and Pedasi provenances were highly unstable for DM leaf yield. ► Retalhuleu provenance was highly productive on wetter sites only. ► Belen Rivas and Volcan combined high DM leaf biomass yield and wide stability.
