GGE biplot and AMMI model to evaluate spine gourd (Momordica dioica Roxb.) for genotype × environment interaction and seasonal adaptation

Abstract

A investigation was carried out to ascertain the GEI, the yield stability and adaptability of 12 advanced spine gourd genotypes (G) in one environments over three crop years (2013, 2014 and 2015). The AMMI and GGE biplot model were used to study the nature of GEI on the fruit yield. First and second component of AMMI model totally explained more than 99% of GEI variations. G7 having maximum trait value with specific adaptation while G2 and G3 were having general adoptability. AMMI 2 biplot revealed high stability of G5 and G2 across environments. Results of GGE biplot model showed that the G4 with the environment of E3 and G7 with the environment of E1 and E2, respectively showed a special adaptability. G7 could be recommended for Northern hill zone of Chhattisgarh. Considering both graphical analysis models of AMMI and GGE biplot could be recommended. The ideal environment, according to both the models, was E2. The results indicated that AMMI and GGE biplot are facilitated visual comparison and informative methods to detect genotypes stability and in the preferential genotypes recommendations.
