<![CDATA[Recently, the development of oil palm varieties with diverse environmental adaptations and high oil productivity has become a critical priority. Analysis of genotype-by-environment (G × E) interactions and stability is a valuable tool for achieving these goals. This study aimed to gather information on the impact of G × E interactions and the stability of several test progenies grown in various environments on bunch component traits. Sixteen progenies were tested in North Sumatra Province and Riau Province. This study used a combined analysis of variance and six stability parameters. Four of the seven bunch component traits showed different responses based on their environment. However, this study did not reveal the influence of G × E interactions on bunch component traits. Nonetheless, a slight G × E variance was observed in the mesocarp-to-fruit (M/F), shell-to-fruit (S/F), kernel-to-fruit (K/F), and kernel-to-bunch (K/B) ratios. Furthermore, we successfully identified several progenies classified as stable with favorable bunch component traits. This shows the potential to produce superior palm oil varieties with good bunch components and the ability to adapt to various environmental conditions.]]>
