GGE biplot analysis of fluted pumpkin (Telfairia occidentalis) landraces evaluated for marketable leaf yield in Southwest Nigeria

AbstractThe study was undertaken with the objective to examine the nature and to quantify the magnitude of genotype×environment interaction (GEI) effects on marketable leaf yield of fluted pumpkin, Telfairia occidentalis (Hook. F.) and to determine the winning genotype (s) for the test environments in Southwest Nigeria. The experiment was conducted using twenty-five landraces of fluted pumpkin in four environments [comprising two different locations (Abeokuta and Akure) for two consecutive years (2012 and 2013)]. Randomized complete block design with three replicates was employed. The combined analysis of variance over environments explained that fluted pumpkin marketable leaf yield was significantly (p
