“…In some cases, sweet potato yields are strongly influenced by GEIs due to the influence of environmental changes (Gruneberg et al, 2005;Gurmu, 2017;Mustamu et al, 2018;Ngailo et al, 2019). Studies have found that GEIs complicated the selection process for yellow passionfruit in Brazil (Oliveira et al, 2014), barley in Turkey (Kendal, E., 2016), finger millet in India (Sood et al, 2016) and cotton in China (Shahzad et al, 2019). Therefore, GEI analysis plays a major part in evaluating the increasing genetic resources that can further promote sweet potato genotypes.…”

Importance of the work:The yield is an important component when determining the probability of success of new high-yielding plant varieties. Objectives: To estimate the influence of genotype-by-environment interactions (GEIs) on sweet potato yields, to select stable genotypes using various methods in multi-environments and to estimate the relationship between environmental factors and sweet potato yields in West Java, Indonesia. Materials & Methods:The genetic materials used were eight new breeding genotypes and two commercial varieties as checks. Field experiments were conducted in five environments (Karawang, Garut, Jatinangor, Cileles and Bandung) in West Java, Indonesia, using a randomized completed block design. Data were analyzed using: combined analysis of variance, parametric and non-parametric stability measurements, genotype plus genotype-versus-environment interaction (GGE) biplots and Pearson's correlation. Results: The environments and GEIs had an effect on sweet potato yields at 37.89% and 45.09%, respectively. The GGE biplot analysis showed that of the five environments, Garut and Karawang were the most discriminative and representative. Therefore, these two environments are recommended as being ideal in West Java for the selection of optimal sweet potato genotypes. The numerical and graphical methods produced the same results, identifying genotypes 57/97(G2) and Rancing (G6) as the optimal genotypes in West Java. The correlation analysis showed that each genotype had a different correlation with the various environmental factors. Main finding: Information on GEIs can be used as a basis for research on sweet potato development in wider environments. The two genotypes have the potential to be developed into new sweet potato superior genotypes.
