the ammi and sreg gge   are among the models that effectively capture the additive and multiplicative components of genotype × environment interaction (gei) and provide meaningful interpretation of multi-environment trials’ data set in the breeding programs. the objective of this study was to assess the effect of gei on grain yield of barely advanced lines and exploit the positive gei effect us...

the objective of this research was to evaluate and to quantify the magnitude of the genotype environment interaction effects on mung bean grain yield and to determine the winning genotype for the test environments. seven mung bean genotypes were tested at three locations for over two years. the grain yield data for each environment (location year combination) was first subjected to analysis of ...

the diallel cross design is frequently utilized to obtain information on genetic effects, estimates of general and specific combining ability (gca and sca) and to identify promising heterotic combinations as well as heterotic patterns. in the present study, heterotic crosses were identified for specific alkaloids in opium poppy (papaver somniferum l.) following yan’s gge biplot model by use of ...

this research was investigated to analyze genotype × environment (ge) interaction for grain yield in durum wheat multi-environment trials (met) conducted in dryland agricultural research stations (dari) using gge (g + ge interaction) biplot methodology and joint regression analysis (b +  s2di). the environment, ge interaction and genotype effects were accounted for 84%, 7.7% and 2.3% of total s...

This paper proposes an alternative method for evaluating the stability and adaptability of maize hybrids using a genotype-ideotype distance index (GIDI) for selection. Data from seven variables were used, obtained through evaluation of 25 maize hybrids at six sites in southern Brazil. The GIDI was estimated by means of the generalized Mahalanobis distance for each plot of the test. We then proc...
