AMMI analysis of genotype × environment interaction on grain yield of sesame (Sesamum indicum L.) genotypes in Iran

Abstract

In this study, we investigated the effect of genotype  environment interaction (GEI) on the grain yield of 15 different sesame genotypes on four test areas (Arak, Birjand, Karaj and Shiraz) in two years (2017-2018). We observed significant differences in all sources of combined variance analysis. The interaction items in AMMI (additive main effects and multiplicative interactions) analysis of variance were divided into three parts, in which the interaction principal components IPC1 and IPC2 items justified about 85% of interactions. Also, IPC2 and residual items were non-significant. Our experiments showed that the superior genotypes were G8 > G13 > G9 > G10 > G15 > G14 > G7. The labile locations were Karaj > Birjand > Arak > Shiraz. Furthermore, G4, G1, G13, G8 and G10 (G4 > G8 > G9 > G10 > G13 > G6, respectively) had the least GEI concerning IPC1 vs. grain yield (IPC1 vs. IPC2, respectively). The recommended genotypes for each region include G9, G2, G3 and G12 for Arak and Birjand; G7, G11 and G14 for Karaj; and G10, G8, G4 and G13 for Shiraz. According to the low environmental impact and the proximity of the IPC values of Shiraz, Arak and Birjand environments, Arak can be considered as the mega-environment for these three locations. The stable genotypes with higher general durability consisted of G4 > G6 > G1 > G2. Based on the AMMI stability value (ASV) and genotype selection index (GSI), Jirouf 13 (G4), Darab 14 (G8), Safi Abad 1 (G9), Ahwaz Local Cultivar (G10) and Isfahan Local Cultivar (G13) were superior genotypes about grain yield and GEI impact, and can be recommended for future investigations.

AMMI Analysis for Stability and Genotype by Environment Interaction on Common Bean (Phaseolus vulgaris L.) Genotypes in Mbeya Region, Tanzania

“…3), the superior genotypes were G5 > G1 and G, and where located on the right side of the graph and close to zero in terms of the IPC1 axis. These results are similar to the observation reported by Movahedi et al [16].…”

“…"AMMI is one of the best analyses for testing genotype stability. In this study, the analysis of 18 Common bean genotypes on three test locations in the grain yield trait gave similar Ftest results to the AMMI analysis performed" by Movahedi et al [17]. Yan et al, [18] pointed out that genotypes with IIPC scores near zero are more representative of an average environment.…”

Genotype-by-environment interaction and selection of superior Physalis peruviana L. genotypes

“…However, the eigenvalues of the first two principal components were greater than one, explaining the interaction in 67.5%. Thus, the analysis of AMMI with PC1 seems appropriate and can explain the effect of the interaction, as it has been shown in G×E interaction studies in tomato (Ceballos-Aguirre et al, 2020) and sesame (Movahedi et al, 2020). There are no studies on cape gooseberry in this regard.…”

“…According to Gauch et al (2008), this model has shown results with a clear agronomic meaning and has been effective due to its ability to capture the G×E interaction. At the same time, this model facilitates the identification of mega-environments and allows breeders to interpret the data and make reliable decisions in the selection of superior genotypes for each environment (Zobel et al, 1988;Gauch et al, 2008;Movahedi et al, 2020).…”
